GlobalProtect Overview Whether checking email from home or updating corporate documents from the airport, the majority of today's employees work outside the physical corporate boundaries. This increased workforce mobility brings increased productivity and flexibility while simultaneously introducing significant security risks. Every time users leave the building with their laptops or mobile devices they are bypassing the corporate firewall and associated policies that are designed to protect both the user and the network. GlobalProtect™ solves the security challenges introduced by roaming users by extending the same next-generation firewall-based policies that are enforced within the physical perimeter to all users, no matter where they are located. The following sections provide conceptual information about the Palo Alto Networks GlobalProtect offering and describe the components of GlobalProtect and the various deployment scenarios: > > > > About the GlobalProtect Components What Client OS Versions are Supported with GlobalProtect? What Features Does GlobalProtect Support? About GlobalProtect Licenses 7 8 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Overview © 2017 Palo Alto Networks, Inc. About the GlobalProtect Components GlobalProtect provides a complete infrastructure for managing your mobile workforce to enable secure access for all your users, regardless of what devices they are using or where they are located. This infrastructure includes the following components: • GlobalProtect Portal • GlobalProtect Gateways • GlobalProtect Client GlobalProtect Portal The GlobalProtect portal provides the management functions for your GlobalProtect infrastructure. Every client system that participates in the GlobalProtect network receives configuration information from the portal, including information about available gateways as well as any client certificates that may be required to connect to the GlobalProtect gateway(s). In addition, the portal controls the behavior and distribution of the GlobalProtect agent software to both Mac and Windows laptops. (On mobile devices, the GlobalProtect app is distributed through the Apple App Store for iOS devices or through Google Play for Android devices.) If you are using the Host Information Profile (HIP) feature, the portal also defines what information to collect from the host, including any custom information you require. You Set Up Access to the GlobalProtect Portal on an interface on any Palo Alto Networks next-generation firewall. GlobalProtect Gateways GlobalProtect gateways provide security enforcement for traffic from GlobalProtect agents/apps. Additionally, if the HIP feature is enabled, the gateway generates a HIP report from the raw host data the clients submit and can use this information in policy enforcement. You can configure different Types of Gateways to provide security enforcement and/or virtual private network (VPN) access for your remote users, or to apply security policy for access to internal resources. You Configure a GlobalProtect Gateway on an interface on any Palo Alto Networks next-generation firewall. You can run both a gateway and a portal on the same firewall, or you can have multiple, distributed gateways throughout your enterprise. GlobalProtect Client The GlobalProtect client software runs on end user systems and enables access to your network resources via the GlobalProtect portals and gateways you have deployed. There are two types of GlobalProtect clients: • The GlobalProtect Agent—Runs on Windows and Mac OS systems and is deployed from the GlobalProtect portal. You configure the behavior of the agent—for example, which tabs the users can see, whether or not users can uninstall the agent—in the client configuration(s) you define on the portal. See Define the GlobalProtect Agent Configurations, Customize the GlobalProtect Agent, and Deploy the GlobalProtect Agent Software for details. • The GlobalProtect App—Runs on iOS, Android, Windows UWP, and Chromebook devices. Users must obtain the GlobalProtect app from the Apple App Store (for iOS), Google Play (for Android), Microsoft Store (for Windows UWP), or Chrome Web Store (for Chromebook). See What Client OS Versions are Supported with GlobalProtect? for more details. The following diagram illustrates how the GlobalProtect portals, gateways, and agents/apps work together to enable secure access for all your users, regardless of what devices they are using or where they are located. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Overview © 9 2017 Palo Alto Networks, Inc. 10 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Overview © 2017 Palo Alto Networks, Inc. What Client OS Versions are Supported with GlobalProtect? Palo Alto Networks supports the GlobalProtect app (also referred to as the GlobalProtect agent) on common desktop, laptop, and mobile devices. We recommend that you configure GlobalProtect on firewalls running PAN-OS 6.1 or a later release and that you install only supported releases of the GlobalProtect app on endpoints. The minimum GlobalProtect app release varies by operating system; to determine the minimum GlobalProtect app release for a specific operating system, refer to the following topics in the Palo Alto Networks® Compatibility Matrix: • Where Can I Install the GlobalProtect App? • What X-Auth IPSec Clients are Supported? Older versions of the GlobalProtect app (releases 1.0 through 2.1) are still supported on the operating systems and PAN-OS releases with which they were released. For minimum PAN-OS release support for GlobalProtect app 2.1 and older releases, refer to the GlobalProtect agent (app) release notes for your specific release on the Software Updates site. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Overview © 11 2017 Palo Alto Networks, Inc. About GlobalProtect Licenses If you simply want to use GlobalProtect to provide a secure, remote access or virtual private network (VPN) solution via single or multiple internal/external gateways, you do not need any GlobalProtect licenses. However, to use some of the more advanced features (such as HIP checks and associated content updates, support for the GlobalProtect mobile app, or IPv6 support) you need to purchase an annual GlobalProtect subscription. This license must be installed on each firewall running a gateway(s) that: • Performs HIP checks • Supports the GlobalProtect app on mobile devices • Provides IPv6 connections For GlobalProtect Clientless VPN, this feature also requires you to install a GlobalProtect subscription on the firewall that hosts the Clientless VPN from the GlobalProtect portal. You also need the GlobalProtect Clientless VPN dynamic updates to use this feature. Feature Subscription Required? Single, external gateway (Windows and Mac) Single or multiple internal gateways Multiple external gateways HIP Checks Mobile app for iOS endpoints, Android endpoints, Chromebooks, and Windows 10 UWP endpoints IPv6 support Clientless VPN See Activate Licenses for information on installing licenses on the firewall. 12 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Overview Get Started For GlobalProtect™ to work, you must set up the infrastructure that allows all of the components to communicate. At a basic level, this means setting up the interfaces and zones to which the GlobalProtect end users connect to access the portal and the gateways to the network. Because the GlobalProtect components communicate over secure channels, you must acquire and deploy the required SSL certificates to the various components. The following sections guide you through the steps to set up the GlobalProtect infrastructure: > Create Interfaces and Zones for GlobalProtect on page 15 > Enable SSL Between GlobalProtect Components on page 17 13 14 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started © 2017 Palo Alto Networks, Inc. Create Interfaces and Zones for GlobalProtect You must configure the following interfaces and zones for your GlobalProtect infrastructure: • GlobalProtect portal—Requires a Layer 3 or loopback interface for the GlobalProtect clients’ connection. If the portal and gateway are on the same firewall, they can use the same interface. The portal must be in a zone that is accessible from outside your network, for example: DMZ. • GlobalProtect gateways—The interface and zone requirements for the gateway depend on whether the gateway you are configuring is external or internal, as follows: • External gateways—Requires a Layer 3 or loopback interface and a logical tunnel interface for the client to establish a VPN tunnel. The Layer 3/loopback interface must be in an external zone, such as DMZ. A tunnel interface can be in the same zone as the interface connecting to your internal resources (for example trust). For added security and better visibility, you can create a separate zone, such as corpvpn. If you create a separate zone for your tunnel interface, you must create security policies that enable traffic to flow between the VPN zone and the trust zone. • Internal gateways—Requires a Layer 3 or loopback interface in your trust zone. You can also create a tunnel interface for access to your internal gateways, but this is not required. For tips on how to use a loopback interface to provide access to GlobalProtect on different ports and addresses, refer to Can GlobalProtect Portal Page be Configured to be Accessed on any Port? For more information about portals and gateways, see About the GlobalProtect Components. STEP 1 | Configure a Layer 3 interface for each portal and/or gateway you plan to deploy. If the gateway and portal are on the same firewall, you can use a single interface for both. As a best practice use static IP addresses for the portal and gateway. Do not attach an interface management profile that allows HTTP, HTTPS, Telnet, or SSH on the interface where you have configured a GlobalProtect portal or gateway because this enables access to your management interface from the Internet. Follow the Best Practices for Securing Administrative Access to ensure that you are securing administrative access to your firewalls in a way that will prevent successful attacks. 1. Select Network > Interfaces > Ethernet or Network > Interfaces > Loopback and then select the interface you want to configure for GlobalProtect. In this example, we are configuring ethernet1/1 as the portal interface. 2. (Ethernet only) Select Layer3 from the Interface Type drop-down. 3. On the Config tab, select the zone to which the portal or gateway interface belongs as follows: • Place portals and external gateways in an untrust zone for access by hosts outside your network, such as l3-untrust. • Place internal gateways in an internal zone, such as l3-trust. • If you have not yet created the zone, select New Zone from the Security Zone drop-down. In the Zone dialog, define a Name for the new zone and then click OK. 4. In the Virtual Router drop-down, select default. 5. Assign an IP address to the interface: GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started © 15 2017 Palo Alto Networks, Inc. • For an IPv4 address, select IPv4 and Add the IP address and network mask to assign to the interface, for example 203.0.11.100/24. • For an IPv6 address, select IPv6, Enable IPv6 on the interface, and Add the IP address and network mask to assign to the interface, for example 2001:1890:12f2:11::10.1.8.160/80. 6. To save the interface configuration, click OK. STEP 2 | On the firewall(s) hosting GlobalProtect gateway(s), configure the logical tunnel interface that will terminate VPN tunnels established by the GlobalProtect agents. IP addresses are not required on the tunnel interface unless you require dynamic routing. In addition, assigning an IP address to the tunnel interface can be useful for troubleshooting connectivity issues. Be sure to enable User-ID in the zone where the VPN tunnels terminate. 1. Select Network > Interfaces > Tunnel and click Add. 2. In the Interface Name field, specify a numeric suffix, such as .2. 3. On the Config tab, expand the Security Zone drop-down to define the zone as follows: • To use your trust zone as the termination point for the tunnel, select the zone from the dropdown. • (Recommended) To create a separate zone for VPN tunnel termination, click New Zone. In the Zone dialog, define a Name for new zone (for example, corp-vpn), select the Enable User Identification check box, and then click OK. 4. In the Virtual Router drop-down, select None. 5. Assign an IP address to the interface: • For an IPv4 address, select IPv4 and Add the IP address and network mask to assign to the interface, for example 203.0.11.100/24. • For an IPv6 address, select IPv6, Enable IPv6 on the interface, and Add the IP address and network mask to assign to the interface, for example 2001:1890:12f2:11::10.1.8.160/80. 6. To save the interface configuration, click OK. STEP 3 | If you created a separate zone for tunnel termination of VPN connections, create a security policy to enable traffic flow between the VPN zone and your trust zone. For example, the following policy rule enables traffic between the corp-vpn zone and the l3-trust zone. STEP 4 | Save the configuration. 16 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started © 2017 Palo Alto Networks, Inc. Enable SSL Between GlobalProtect Components All interaction between the GlobalProtect components occurs over an SSL/TLS connection. Therefore, you must generate and/or install the required certificates before configuring each component so that you can reference the appropriate certificate(s) in the configurations. The following sections describe the supported methods of certificate deployment, descriptions and best practice guidelines for the various GlobalProtect certificates, and provide instructions for generating and deploying the required certificates: • About GlobalProtect Certificate Deployment on page 17 • GlobalProtect Certificate Best Practices on page 17 • Deploy Server Certificates to the GlobalProtect Components on page 20 About GlobalProtect Certificate Deployment There are three basic approaches to Deploy Server Certificates to the GlobalProtect Components on page 20: • (Recommended) Combination of third-party certificates and self-signed certificates—Because the end clients will be accessing the portal prior to GlobalProtect configuration, the client must trust the certificate to establish an HTTPS connection. • Enterprise Certificate Authority—If you already have your own enterprise CA, you can use this internal CA to issue certificates for each of the GlobalProtect components and then import them onto the firewalls hosting your portal and gateway(s). In this case, you must also ensure that the end user systems/mobile devices trust the root CA certificate used to issue the certificates for the GlobalProtect services to which they must connect. • Self-Signed Certificates—You can generate a self-signed CA certificate on the portal and use it to issue certificates for all of the GlobalProtect components. However, this solution is less secure than the other options and is therefore not recommended. If you do choose this option, end users will see a certificate error the first time they connect to the portal. To prevent this, you can deploy the self-signed root CA certificate to all end user systems manually or using some sort of centralized deployment, such as an Active Directory Group Policy Object (GPO). GlobalProtect Certificate Best Practices The following table summarizes the SSL/TLS certificates you will need, depending on which features you plan to use: Certificate Usage Issuing Process/Best Practices CA certificate Used to sign certificates issued to the GlobalProtect components. If you plan to use self-signed certificates, a best practice is to generate a CA certificate on the portal and then use that certificate to issue the required GlobalProtect certificates. Portal server certificate Enables GlobalProtect agents and apps to establish an HTTPS connection with the portal. • This certificate is identified in an SSL/TLS service profile. You assign the portal server certificate by selecting its associated service profile in a portal configuration. • Use a certificate from a well-known, third-party CA. This is the most secure option and ensures GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started © 17 2017 Palo Alto Networks, Inc. Certificate Usage Issuing Process/Best Practices • • • • Gateway server certificate Enables GlobalProtect agents and apps to establish an HTTPS connection with the gateway. that the user endpoints can establish a trust relationship with the portal and without requiring you to deploy the root CA certificate. If you do not use a well-known, public CA, you should export the root CA certificate that was used to generate the portal server certificate to all endpoints that run the GlobalProtect agent or application. Exporting this certificate prevents the end users from seeing certificate warnings during the initial portal login. The Common Name (CN) and, if applicable, the Subject Alternative Name (SAN) fields of the certificate must match the IP address or FQDN of the interface that hosts the portal. In general, a portal must have its own server certificate. However, if you are deploying a single gateway and portal on the same interface for basic VPN access, you must use the same certificate for both the gateway and the portal. If you configure a gateway and portal on the same interface, we also recommend that you use the same certificate profile and SSL/TLS service profile for both the gateway and portal. If they do not use the same certificate profile and SSL/TLS service profile, the gateway configuration takes precedence over the portal configuration during the SSL handshake. • This certificate is identified in an SSL/TLS service profile. You assign the portal server certificate by selecting its associated service profile in a gateway configuration. • Generate a CA certificate on the portal and use that CA certificate to generate all gateway certificates. • The CN and, if applicable, the SAN fields of the certificate must match the FQDN or IP address of the interface where you plan to configure the gateway. • The portal distributes the gateway root CA certificates to agents in the client configuration, so the gateway certificates do not need to be issued by a public CA. • In general, each gateway must have its own server certificate. However, if you are deploying a single gateway and portal on the same interface for basic VPN access, you must use a single server certificate for both components.As a best practice, use a certificate that a public CA signed. • If you configure a gateway and portal on the same interface, we also recommend that you use the same certificate profile and SSL/TLS service 18 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started © 2017 Palo Alto Networks, Inc. Certificate Usage Issuing Process/Best Practices profile for both the gateway and portal. If they do not use the same certificate profile and SSL/TLS service profile, the gateway configuration takes precedence over the portal configuration during the SSL handshake. (Optional) Client certificate (Optional) Machine certificates Used to enable mutual authentication in establishing an HTTPS session between the GlobalProtect agents and the gateways/portal. This ensures that only devices with valid client certificates are able to authenticate and connect to the network. • For simplified deployment of client certificates, configure the portal to deploy the client certificate to the agents upon successful login using either of the following methods: A machine certificate is a client certificate that is issued to a device. Each machine certificate identifies the device in the subject field (for example, CN=laptop1.example.com) instead of a user. The certificate ensures that only trusted endpoints can connect to gateways or the portal. • Use one of the following supported digest algorithms when you generate client certificates for GlobalProtect endpoints: sha1, sha256, or sha384. Sha512 is not supported with client certificates. • If you plan to use the pre-logon feature, use your own PKI infrastructure to deploy machine certificates to each client system prior to enabling GlobalProtect access. This approach is important for ensuring security. Machine certificates are required for users whose connect method is prelogon, which enables • Use a single client certificate across all GlobalProtect agents that receive the same configuration. You assign the Local client certificate by uploading the certificate to the portal and selecting it in a portal agent configuration. • Use simple certificate enrollment protocol (SCEP) to enable the GlobalProtect portal to deploy unique client certificates to your GlobalProtect agents. You enable this by configuring a SCEP profile and then selecting that profile in a portal agent configuration. • Use one of the following supported digest algorithms when you generate client certificates for GlobalProtect endpoints: sha1, sha256, or sha384. Sha512 is not supported with client certificates. • You can use other mechanisms to deploy unique client certificates to each client system for use in authenticating the end user. • Consider testing your configuration without the client certificate first, and then add the client certificate after you are sure that all other configuration settings are correct. For more information, see Remote Access VPN with Pre-Logon. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started © 19 2017 Palo Alto Networks, Inc. Certificate Usage Issuing Process/Best Practices GlobalProtect to establish a VPN tunnel before the user logs in. Table: GlobalProtect Certificate Requirements For details about the types of keys for secure communication between the GlobalProtect endpoint and the portals and gateways, see Reference: GlobalProtect Agent Cryptographic Functions. Deploy Server Certificates to the GlobalProtect Components The following table shows the best practice steps for deploying SSL/TLS certificates to the GlobalProtect components: • Import a server certificate from a well-known, third-party CA. Use a server certificate from a well-known, third-party CA for the GlobalProtect portal. This practice ensures that the end users are able to establish an HTTPS connection without seeing warnings about untrusted certificates. The CN and, if applicable, the SAN fields of the certificate must match the FQDN or IP address of the interface where you plan to configure the portal or the device check-in interface on a third-party mobile endpoint management system. Wildcard matches are supported. Before you import a certificate, make sure the certificate and key files are accessible from your management system and that you have the passphrase to decrypt the private key. 1. 2. 3. 4. 5. 6. 7. 8. Select Device > Certificate Management > Certificates > Device Certificates. Click Import. Use the Local certificate type (the default). Enter a Certificate Name. Enter the path and name to the Certificate File received from the CA, or Browse to find the file. Select Encrypted Private Key and Certificate (PKCS12) as the File Format. Enter the path and name to the PKCS#12 file in the Key File field or Browse to find it. Enter and re-enter the Passphrase that was used to encrypt the private key and then click OK to import the certificate and key. • Create the root CA certificate for issuing self-signed certificates for the GlobalProtect components. Create the Root CA certificate on the portal and use it to issue server certificates for the gateways and, optionally, for clients. Before deploying self-signed certificates, you must create the root CA certificate that signs the certificates for the GlobalProtect components: 1. Select Device > Certificate Management > Certificates > Device Certificates and then click Generate. 2. Use the Local certificate type (the default). 3. Enter a Certificate Name, such as GlobalProtect_CA. The certificate name cannot contain spaces. 20 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started © 2017 Palo Alto Networks, Inc. 4. Do not select a value in the Signed By field. (Without a selection for Signed By, the certificate is selfsigned.) 5. Select the Certificate Authority check box. 6. Click OK to generate the certificate. • Use the root CA on the portal to generate a self-signed server certificate. Generate server certificates for each gateway you plan to deploy and optionally for the management interface of the third-party mobile endpoint management system (if this interface is where the gateways retrieve HIP reports). In the gateway server certificates, the values in the CN and SAN fields must be identical. If the values differ, the GlobalProtect agent detects the mismatch and does not trust the certificate. Self-signed certificates contain a SAN field only if you add a Host Name attribute. As an alternative method, you can Use Simple Certificate Enrollment Protocol (SCEP) to request a server certificate from your enterprise CA. 1. Select Device > Certificate Management > Certificates > Device Certificates and then click Generate. 2. Use the Local certificate type (the default). 3. Enter a Certificate Name. This name cannot contain spaces. 4. In the Common Name field, enter the FQDN (recommended) or IP address of the interface where you plan to configure the gateway. 5. In the Signed By field, select the GlobalProtect_CA you created. 6. In the Certificate Attributes section, Add and define the attributes that uniquely identify the gateway. Keep in mind that if you add a Host Name attribute (which populates the SAN field of the certificate), it must be the same as the value you defined for the Common Name. 7. Configure cryptographic settings for the server certificate including encryption Algorithm, key length (Number of Bits), Digest algorithm and Expiration (days). 8. Click OK to generate the certificate. • Use Simple Certificate Enrollment Protocol (SCEP) to request a server certificate from your enterprise CA. Configure separate SCEP profiles for each portal and gateway you plan to deploy. Then use the specific SCEP profile to generate the server certificate for each GlobalProtect component. In portal and gateway server certificates, the value of the CN field must include the FQDN (recommended) or IP address of the interface where you plan to configure the portal or gateway and must be identical to the SAN field. To comply with the U.S. Federal Information Processing Standard (FIPS), you must also enable mutual SSL authentication between the SCEP server and the GlobalProtect portal. (FIPS-CC operation is indicated on the firewall login page and in its status bar.) After you commit the configuration, the portal attempts to request a CA certificate using the settings in the SCEP profile. If successful, the firewall hosting the portal saves the CA certificate and displays it in the list of Device Certificates. 1. Configure a SCEP Profile for each GlobalProtect portal or gateway: GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started © 21 2017 Palo Alto Networks, Inc. 1. Enter a Name that identifies the SCEP profile and the component to which you deploy the server certificate. If this profile is for a firewall with multiple virtual systems capability, select a virtual system or Shared as the Location where the profile is available. 2. (Optional) Configure a SCEP Challenge-response mechanism between the PKI and portal for each certificate request. Use either a Fixed challenge password which you obtain from the SCEP server or a Dynamic password where the portal-client submits a username and OTP of your choice to the SCEP Server. For a Dynamic SCEP challenge, this can be the credentials of the PKI administrator. 3.

GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started © 23 2017 Palo Alto Networks, Inc. 24 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Get Started Authentication The GlobalProtect™ portal and gateway must authenticate the end-user before it allows access to GlobalProtect resources.

About GlobalProtect User Authentication The first time a GlobalProtect client connects to the portal, the user is prompted to authenticate to the portal. If authentication succeeds, the GlobalProtect portal sends the GlobalProtect configuration, which includes the list of gateways to which the agent can connect, and optionally a client certificate for connecting to the gateways. After successfully downloading and caching the configuration, the client attempts to connect to one of the gateways specified in the configuration. Because these components provide access to your network resources and settings, they also require the end user to authenticate. The appropriate level of security required on the portal and gateways varies with the sensitivity of the resources that the gateway protects. GlobalProtect provides a flexible authentication framework that allows you to choose the authentication profile and certificate profile that are appropriate to each component. • Supported GlobalProtect Authentication Methods • How Does the Agent or App Know What Credentials to Supply? • How Does the Agent Know Which Certificate to Supply? Supported GlobalProtect Authentication Methods The following topics describe the authentication methods that GlobalProtect supports and provide usage guidelines for each method. • • • • • Local Authentication on page 27 External Authentication on page 27 Client Certificate Authentication on page 27 Two-Factor Authentication on page 28 Multi-Factor Authentication for Non-Browser-Based Applications on page 29 Local Authentication Both the user account credentials and the authentication mechanisms are local to the firewall. This authentication mechanism is not scalable because it requires an account for every GlobalProtect user and is, therefore, advisable for only very small deployments. External Authentication The user authentication functions are performed by an external LDAP, Kerberos, TACACS+, SAML, or RADIUS service (including support for two-factor, token-based authentication mechanisms, such as onetime password (OTP) authentication). To enable external authentication: • Create a server profile with settings for access to the external authentication service. • Create an authentication profile that refers to the server profile. • Specify client authentication in the portal and gateway configurations and optionally specify the OS of the endpoint that will use these settings. You can use different authentication profiles for each GlobalProtect component. See Set Up External Authentication on page 31 for instructions. See Remote Access VPN (Authentication Profile) on page 201 for an example configuration. Client Certificate Authentication For enhanced security, you can configure the portal or gateway to use a client certificate to obtain the username and authenticate the user before granting access to the system. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 27 2017 Palo Alto Networks, Inc. • To authenticate the user, one of the certificate fields, such as the Subject Name field, must identify the username. • To authenticate the endpoint, the Subject field of the certificate must identify the device type instead of the username. (With the pre-logon connect methods, the portal or gateway authenticates the endpoint before the user logs in.) For an agent configuration profile that specifies client certificates, each user receives a client certificate. The mechanism for providing the certificates determines whether a certificate is unique to each client or the same for all clients under that agent configuration: • To deploy client certificates that are unique to each user and device, use SCEP. When a user first logs in, the portal requests a certificate from the enterprise’s PKI. The portal obtains a unique certificate and deploys it to the client. • To deploy the same client certificate to all users that receive an agent configuration, deploy a certificate that is Local to the firewall. Use an optional certificate profile to verify the client certificate that a client presents with a connection request. The certificate profile specifies the contents of the username and user domain fields; lists CA certificates; criteria for blocking a session; and offers ways to determine the revocation status of CA certificates. Because the certificate is part of the authentication of the endpoint or user for a new session, you must pre-deploy certificates used in certificate profiles to the endpoints before the users’ initial portal login. The certificate profile specifies which certificate field contains the username. If the certificate profile specifies Subject in the Username Field, the certificate presented by the client must contain a commonname for the client to connect. If the certificate profile specifies a Subject-Alt with an Email or Principal Name as the Username Field, the certificate from the client must contain the corresponding fields, which will be used as the username when the GlobalProtect agent authenticates to the portal or gateway. GlobalProtect also supports authentication by common access cards (CACs) and smart cards, which rely on a certificate profile. With these cards, the certificate profile must contain the root CA certificate that issued the certificate to the smart card or CAC. If you specify client certificate authentication, you should not configure a client certificate in the portal configuration because the client system provides it when the user connects. For an example of how to configure client certificate authentication, see Remote Access VPN (Certificate Profile) on page 204. Two-Factor Authentication With two-factor authentication, the portal or gateway uses two mechanisms to authenticate a user, such as a one-time password in addition to AD login credentials. You can enable two-factor authentication on the portal and gateways by configuring a certificate profile and an authentication profile and adding them both to the portal and/or gateway configuration. You can configure the portal and gateways to use the same authentication methods or use different methods. Regardless, with two-factor authentication, the client must successfully authenticate by the two mechanisms that the component demands before it grants access. If the certificate profile specifies a Username Field from which GlobalProtect can obtain a username, the external authentication service automatically uses the username to authenticate the user to the external authentication service specified in the authentication profile. For example, if the Username Field in the certificate profile is set to Subject, the value in the common-name field of the certificate is used as the username when the authentication server tries to authenticate the user. If you do not want to force users to authenticate with a username from the certificate, make sure the certificate profile is set to None for the Username Field. See Remote Access VPN with Two-Factor Authentication on page 207 for an example configuration. 28 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. Multi-Factor Authentication for Non-Browser-Based Applications (Windows and Mac endpoints only) For sensitive, non-browser-based network resources (for example, financial applications or software development applications) that may require additional authentication, GlobalProtect clients can now notify and prompt the user to perform the timely, multi-factor authentication needed to access these resources. How Does the Agent or App Know What Credentials to Supply? By default, the GlobalProtect agent attempts to use the same login credentials for the gateway that it used for portal login. In the simplest case, where the gateway and the portal use the same authentication profile and/or certificate profile, the agent will connect to the gateway transparently. On a per-agent configuration basis, you can also customize which GlobalProtect portal and gateways— internal, external, or manual only—require different credentials (such as unique OTPs). This enables the GlobalProtect portal or gateway to prompt for the unique OTP without first prompting for the credentials specified in the authentication profile. There are two options for modifying the default agent authentication behavior so that authentication is both stronger and faster: • Cookie Authentication on the Portal or Gateway on page 29 • Credential Forwarding to Some or All Gateways on page 29 Cookie Authentication on the Portal or Gateway Cookie authentication simplifies the authentication process for end users because they will no longer be required to log in to both the portal and the gateway in succession or enter multiple OTPs for authenticating to each. This improves the user experience by minimizing the number of times that users must enter credentials. In addition, cookies enable use of a temporary password to re-enable VPN access after the user’s password expires. You can configure cookie authentication settings independently for the portal and for individual gateways, (for example, you can impose a shorter cookie lifetime on gateways that protect sensitive resources). After the portal or gateways deploy an authentication cookie to the endpoint, the portal and gateways both rely on the same cookie to authenticate the user. When the agent presents the cookie, the portal or gateway evaluates whether the cookie is valid based on the configured cookie lifetime. If the cookie expires, GlobalProtect automatically prompts the user to authenticate with the portal or gateway. When authentication is successful, the portal or gateway issues the replacement authentication cookie to the endpoint and the validity period starts over. Consider the following example where you configure the cookie lifetime for the portal—which does not protect sensitive information—as 15 days, but configure the cookie lifetime for gateways—which do protect sensitive information—as 24 hours. When the user first authenticates with the portal, the portal issues the authentication cookie. If after five days, the user attempted to connect to the portal, the authentication cookie would still be valid. However, if after five days the user attempted to connect to the gateway, the gateway would evaluate the cookie lifetime and determine it expired (5 days > 24 hours). The agent would then automatically prompt the user to authenticate with the gateway and, on successful authentication, receive a replacement authentication cookie. The new authentication cookie would then be valid for another 15 days on the portal and another 24 hours on the gateways. For an example of how to use this option, see Set Up Two-Factor Authentication on page 45. Credential Forwarding to Some or All Gateways With two-factor authentication, you can specify the portal and/or types of gateways (internal, external, or manual only) that prompt for their own set of credentials. This option speeds up the authentication process when the portal and the gateway require different credentials (either different OTPs or different GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 29 2017 Palo Alto Networks, Inc. login credentials entirely). For each portal or gateway that you select, the agent will not forward credentials, allowing you to customize the security for different GlobalProtect components. For example, you can have the same security on your portals and internal gateways, while requiring a second factor OTP or a different password for access to those gateways that provide access to your most sensitive resources. For an example of how to use this option, see Set Up Two-Factor Authentication on page 45. How Does the Agent Know Which Certificate to Supply? When you configure GlobalProtect to use client certificates for authentication on Mac or Windows endpoints, GlobalProtect must present a valid client certificate to authenticate with the portal and/or gateways. For a client certificate to be valid, it must meet the following four requirements: • Issued by the certificate authority (CA) you defined in the Certificate Profile of your portal and gateway configurations. • Specifies the client authentication purpose, which the certificate administrator specifies when creating the certificate. • Located in the certificate store as configured in the GlobalProtect portal agent configuration. By default, the GlobalProtect agent first looks for a valid certificate in the user store and, if none exists, then looks in the machine store. Because the user store takes precedence, if the GlobalProtect agent locates a certificate in the user store, it will not look in the machine store. To force the GlobalProtect agent to look for certificates in only one certificate store, configure the Client Certificate Store Lookup option in the appropriate GlobalProtect portal agent configuration. • Match any additional purpose specified in the GlobalProtect portal agent configuration. To specify an additional purpose, you must identify the object identifier (OID) for the certificate and configure the Extended Key Usage OID value in the appropriate GlobalProtect portal agent configuration. An OID is a numeric value that identifies the application or service for which to use a certificate and that is automatically attached to a certificate when it is created by a certificate authority (CA). For more information on specifying a common or custom OID, see Certificate Selection by OID. When only one client certificate meets the requirements above, the agent automatically selects and uses that client certificate for authentication. However, when multiple client certificates meet the these requirements, GlobalProtect prompts the user to select the client certificate from a list of valid client certificates on the endpoint. While GlobalProtect requires users to select the client certificate only when they first connect, users might not know which certificate to select. In this case, we recommend you to narrow the list of available client certificates by certificate purpose (as indicated by the OID) and certificate store. For more information on these and other settings you can configure to customize your agent, see Customize the GlobalProtect Agent. 30 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. Set Up External Authentication The following workflows describe how to set up the GlobalProtect portal and gateways to use an external authentication service. The supported authentication services are LDAP, Kerberos, RADIUS, SAML, or TACACS+. These workflows also describe how to create an optional authentication profile that a portal or gateway can use to identify the external authentication service. This step is optional for external authentication because the authentication profile also can specify the local authentication database or None. GlobalProtect also supports local authentication. To use local authentication, create a local user database (Device > Local User Database) that contains the users and groups to which you want to allow VPN access and then refer to that database in the authentication profile. For more information, see Supported GlobalProtect Authentication Methods on page 27 or watch a video. The options for setting up external authentication include: • • • • Set Up LDAP Authentication on page 31 Set Up SAML Authentication on page 33 Set Up Kerberos Authentication on page 34 Set Up RADIUS or TACACS+ Authentication on page 35 Set Up LDAP Authentication LDAP is often used by organizations as a central repository for user information and as an authentication service. It can also be used to store the role information for application users. STEP 1 | Create a server profile. The server profile identifies the external authentication service and instructs the firewall how to connect to that authentication service and access the authentication credentials for your users. When you use LDAP to connect to Active Directory (AD), you must create a separate LDAP server profile for every AD domain. 1. Select Device > Server Profiles and select the LDAP profile. 2. Click Add and enter a Profile Name, such as GP-User-Auth. 3. If this profile is for a firewall with multiple virtual systems capability, select a virtual system or Shared as the Location where the profile is available. 4. Select the Type of LDAP server. 5. Click Add in the Servers section and then enter the necessary information for connecting to the authentication server, including the server Name, IP address or FQDN of the Server, and Port. 6. Specify settings to enable the authentication service to authenticate the firewall. Enter the Bind DN and Password. 7. If you want the device to use SSL or TLS for a more secure connection with the directory server, select the Require SSL/TLS secured connection check box (selected by default). The protocol that the device uses depends on the server Port: • 389 (default)—TLS (Specifically, the device uses the StartTLS operation, which upgrades the initial plaintext connection to TLS.) • 636—SSL • Any other port—The device first attempts to use TLS. If the directory server doesn’t support TLS, the device falls back to SSL. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 31 2017 Palo Alto Networks, Inc. 8. For additional security, select the Verify Server Certificate for SSL sessions check box so that the device verifies the certificate that the directory server presents for SSL/TLS connections. To enable verification, you also have to select the Require SSL/TLS secured connection check box. For verification to succeed, the certificate must meet one of the following conditions: • It is in the list of device certificates: Device > Certificate Management > Certificates > Device Certificates. Import the certificate into the device, if necessary. • The certificate signer is in the list of trusted certificate authorities: Device > Certificate Management > Certificates > Default Trusted Certificate Authorities. 9. Click OK to save the server profile. STEP 2 | (Optional) Create an authentication profile. The authentication profile specifies the server profile for the portal or gateways to use when they authenticate users. On a portal or gateway, you can assign one or more authentication profiles in one or more client authentication profiles. For descriptions of how an authentication profile within a client authentication profile supports granular user authentication, see Configure a GlobalProtect Gateway and Set Up Access to the GlobalProtect Portal. To enable users to connect and change their own expired passwords without administrative intervention, consider using a pre-logon connect method. See Remote Access VPN with Pre-Logon for details. If users allow their passwords to expire, you may assign a temporary LDAP password to enable them to log in to the VPN. In this case, the temporary password may be used to authenticate to the portal, but the gateway login may fail because the same temporary password cannot be re-used. To prevent this, enable an authentication override in the portal configuration (Network > GlobalProtect > Portal) to enable the agent to use a cookie to authenticate to the portal and use the temporary password to authenticate the gateway. 1. 2. 3. 4. 5. Select Device > Authentication Profile and Add a new profile. Enter a Name for the profile and then select LDAP as the authentication Type. Select the LDAP authentication Server Profile that you created in 1 from the drop-down. Enter sAMAccountName as the Login Attribute. Set the Password Expiry Warning to specify the number of days before password expiration that users will be notified. By default, users will be notified seven days prior to password expiration (range is 1-255). Because users must change their passwords before the end of the expiration period, make sure you provide a notification period that is adequate for your user base to ensure continued access to the VPN. To use this feature, you must specify one of the following types of LDAP servers in your LDAP server profile: active-directory, e-directory, or sun. Users cannot access the VPN if their passwords expire unless you enable pre-logon. 6. Configure an optional custom expiry message to include additional instructions, such as help desk contact information or a link to a password portal where users can change their passwords (see Customize the GlobalProtect Agent). 7. Specify the domain name and username format. The device combines the User Domain and Username Modifier values to modify the domain/username string that a user enters during login. The device uses the modified string for authentication and uses the User Domain value for User-ID group mapping. Modifying user input is useful when the authentication service requires domain/username strings in a particular format and you don’t want to rely on users to correctly enter the domain. You can select from the following options: • To send only the unmodified user input, leave the User Domain blank (the default) and set the Username Modifier to the variable %USERINPUT% (the default). 32 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. • To prepend a domain to the user input, enter a User Domain and set the Username Modifier to %USERDOMAIN%\%USERINPUT%. • To append a domain to the user input, enter a User Domain and set the Username Modifier to %USERINPUT%@%USERDOMAIN%. If the Username Modifier includes the %USERDOMAIN% variable, the User Domain value replaces any domain string that the user enters. If the User Domain is blank, that means the device removes any user-entered domain string. 8. Select the Advanced tab. 9. In the Allow List, Add and then select the users and groups that are allowed to authenticate with this profile. Selecting the predefined all option allows every user to authenticate. By default, the list has no entries, which means no users can authenticate. 10.Click OK. STEP 3 | Commit the configuration. Click Commit. Set Up SAML Authentication Security Assertion Markup Language (SAML) is an XML-based, open-standard data format for exchanging authentication and authorization data between parties, in particular, between an identity provider (IdP) and a service provider. SAML is a product of the OASIS Security Services Technical Committee. STEP 1 | Create a server profile. The server profile identifies the external authentication service and instructs the firewall how to connect to that authentication service and access the authentication credentials for your users. 1. Select Device > Server Profiles and select the SAML Identity Provider profile. 2. Click Add and enter a Profile Name, such as GP-User-Auth. 3. If this profile is for a firewall with multiple virtual systems capability, select a virtual system or Shared as the Location where the profile is available. 4. Import the IdP metadata file. Refer to SAML 2.0 Authentication for details. Alternatively, if the IdP doesn’t provide a metadata file, Add the server profile and then enter the connection and registration information. 5. Click OK to save the server profile. STEP 2 | (Optional) Create an authentication profile. The authentication profile specifies the server profile for the portal or gateways to use when they authenticate users. On a portal or gateway, you can assign one or more authentication profiles in one or more client authentication profiles. For descriptions of how an authentication profile within a client authentication profile supports granular user authentication, see Configure a GlobalProtect Gateway and Set Up Access to the GlobalProtect Portal. SAML authentication does not support the pre-logon connect method that enables users to connect and change their own expired passwords without administrative intervention (Remote Access VPN with Pre-Logon). 1. Select Device > Authentication Profile and Add a new profile. 2. Enter a Name for the profile and then select SAML as the authentication Type. 3. Select the SAML authentication Server Profile that you created in 1 from the drop-down. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 33 2017 Palo Alto Networks, Inc. 4. Select the following to configure certificate authentication between the firewall and the SAML identity provider. Refer to SAML 2.0 Authentication for details. • The Request Signing Certificate that the firewall uses to sign messages it sends to the IdP. • The Certificate Profile that the firewall uses to validate the Identity Provider Certificate. 5. Specify the username and admin role formats. • Specify the Username Attribute and User Group Attribute. Unlike other types of external authentication, there is no User Domain attribute in the authentication profiles for SAML. • (Optional) If you will use this profile to authenticate administrative accounts that you manage in the IdP identity store, specify the Admin Role Attribute and Access Domain Attribute also. 6. Select the Advanced tab. 7. In the Allow List, Add and then select the users and groups that are allowed to authenticate with this profile. Selecting the predefined all option allows every user to authenticate. By default, the list has no entries, which means no users can authenticate. Make sure the username in the Allow List matches the username returned from the SAML IdP server. 8. Click OK. STEP 3 | Commit the configuration. Click Commit. Set Up Kerberos Authentication Kerberos is a computer network authentication protocol that works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. STEP 1 | Create a server profile. The server profile identifies the external authentication service and instructs the firewall how to connect to that authentication service and access the authentication credentials for your users. 1. Select Device > Server Profiles and select the Kerberos profile. 2. Click Add and enter a Profile Name, such as GP-User-Auth. 3. If this profile is for a firewall with multiple virtual systems capability, select a virtual system or Shared as the Location where the profile is available. 4. Click Add in the Servers section and then enter the necessary information for connecting to the authentication server, including the server Name, IP address or FQDN of the Server, and Port. 5. Click OK to save the server profile. STEP 2 | (Optional) Create an authentication profile. The authentication profile specifies the server profile for the portal or gateways to use when they authenticate users. On a portal or gateway, you can assign one or more authentication profiles in one or more client authentication profiles. For descriptions of how an authentication profile within a client authentication profile supports granular user authentication, see Configure a GlobalProtect Gateway and Set Up Access to the GlobalProtect Portal. To enable users to connect and change their own expired passwords without administrative intervention, consider using a pre-logon connect method. See Remote Access VPN with Pre-Logon for details. 34 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. 1. 2. 3. 4. Select Device > Authentication Profile and Add a new profile. Enter a Name for the profile and then select Kerberos as the authentication Type. Select the Kerberos authentication Server Profile that you created in 1 from the drop-down. Specify the domain name and username format. The device combines the User Domain and Username Modifier values to modify the domain/username string that a user enters during login. The device uses the modified string for authentication and uses the User Domain value for User-ID group mapping. Modifying user input is useful when the authentication service requires domain/username strings in a particular format and you don’t want to rely on users to correctly enter the domain. You can select from the following options: • To send only the unmodified user input, leave the User Domain blank (the default) and set the Username Modifier to the variable %USERINPUT% (the default). • To prepend a domain to the user input, enter a User Domain and set the Username Modifier to %USERDOMAIN%\%USERINPUT%. • To append a domain to the user input, enter a User Domain and set the Username Modifier to %USERINPUT%@%USERDOMAIN%. If the Username Modifier includes the %USERDOMAIN% variable, the User Domain value replaces any domain string that the user enters. If the User Domain is blank, that means the device removes any user-entered domain string. 5. Configure Kerberos single sign-on (SSO) if your network supports it: • Enter the Kerberos Realm (up to 127 characters). This is the hostname portion of the user login name. For example, the user account name user@EXAMPLE.LOCAL has the realm EXAMPLE.LOCAL. • Specify a Kerberos Keytab file: click the Import link, Browse to the keytab file, and click OK. During authentication, the endpoint first tries to use the keytab to establish SSO. If it succeeds, and the user attempting access is in the Allow List, authentication succeeds immediately. Otherwise, the authentication process falls back to manual (username/password) authentication of the specified Type. The Type doesn’t have to be Kerberos. To change this behavior so that users can authenticate only using Kerberos, set Use Default Authentication on Kerberos Authentication Failure to No in a GlobalProtect portal agent configuration. 6. Select the Advanced tab. 7. In the Allow List, Add and then select the users and groups that are allowed to authenticate with this profile. Selecting the predefined all option allows every user to authenticate. By default, the list has no entries, which means no users can authenticate. STEP 3 | Save your changes and commit the configuration. Click OK, and then Commit. Set Up RADIUS or TACACS+ Authentication RADIUS is a client/server protocol and software that enables remote access servers to communicate with a central server to authenticate dial-in users and authorize their access to the requested system or service. TACACS+ is a well-established authentication protocol common to UNIX networks that allows a remote access server to forward a user's logon password to an authentication server to determine whether access can be allowed to a given system. STEP 1 | Create a server profile. The server profile identifies the external authentication service and instructs the firewall how to connect to that authentication service and access the authentication credentials for your users. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 35 2017 Palo Alto Networks, Inc. If you want to Enable Delivery of GlobalProtect Client VSAs to a RADIUS Server, you must create a RADIUS server profile. 1. Select Device > Server Profiles and select the type of profile (RADIUS or TACACS+). 2. Click Add and enter a Profile Name, such as GP-User-Auth. 3. If this profile is for a firewall with multiple virtual systems capability, select a virtual system or Shared as the Location where the profile is available. 4. Configure the following Server Settings. These settings to all servers you include in the profile. • Timeout (sec)—The number of seconds before a server connection request times out due to lack of response from the authentication server. • Authentication Protocol—Select the protocol to use for connections to the authentication server. Choices are CHAP, PAP, or Auto. • (RADIUS only) Retries—The number of times the firewall trys connecting to the authentication server before dropping the request. • (TACACS+ only) Use single connection for all authentication to allow all TACACS+ authentication requests to occur over a single TCP session rather than separate sessions for each request. 5. Click Add in the Servers section and then enter the necessary information for connecting to the authentication server, including the server Name, IP address or FQDN of the Server, and Port. 6. Specify settings to enable the authentication service to authenticate the firewall. Enter the shared Secret when adding the server entry. 7. Click OK to save the server profile. STEP 2 | (Optional) Create an authentication profile. The authentication profile specifies the server profile for the portal or gateways to use when they authenticate users. On a portal or gateway, you can assign one or more authentication profiles in one or more client authentication profiles. For descriptions of how an authentication profile within a client authentication profile supports granular user authentication, see Configure a GlobalProtect Gateway and Set Up Access to the GlobalProtect Portal. To enable users to connect and change their own expired passwords without administrative intervention, consider using a pre-logon connect method. See Remote Access VPN with Pre-Logon for details. 1. Select Device > Authentication Profile and Add a new profile. 2. Enter a Name for the profile and then select the authentication Type (RADIUS or TACACS+). 3. Select the RADIUS or TACACS+ authentication Server Profile. that you created in 1 from the dropdown. 4. (RADIUS only) Enable Retrieve user group from RADIUS if you want to include this information in the authentication profile. 5. Specify the domain name and username format. The device combines the User Domain and Username Modifier values to modify the domain/username string that a user enters during login. The device uses the modified string for authentication and uses the User Domain value for User-ID group mapping. Modifying user input is useful when the authentication service requires domain/username strings in a particular format and you don’t want to rely on users to correctly enter the domain. You can select from the following options: • To send only the unmodified user input, leave the User Domain blank (the default) and set the Username Modifier to the variable %USERINPUT% (the default). • To prepend a domain to the user input, enter a User Domain and set the Username Modifier to %USERDOMAIN%\%USERINPUT%. 36 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. • To append a domain to the user input, enter a User Domain and set the Username Modifier to %USERINPUT%@%USERDOMAIN%. If the Username Modifier includes the %USERDOMAIN% variable, the User Domain value replaces any domain string that the user enters. If the User Domain is blank, that means the device removes any user-entered domain string. 6. Select the Advanced tab. 7. In the Allow List, Add and then select the users and groups that are allowed to authenticate with this profile. Selecting the predefined all option allows every user to authenticate. By default, the list has no entries, which means no users can authenticate. 8. Click OK. STEP 3 | Commit the configuration. Click Commit. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 37 2017 Palo Alto Networks, Inc. Set Up Client Certificate Authentication With the optional client certificate authentication, the agent/app presents a client certificate along with its connection request to the GlobalProtect portal or gateway. The portal or gateway can use either a shared or unique client certificate to validate that the user or device belongs to your organization. The methods for deploying client certificates depend on the security requirements for your organization: • Deploy Shared Client Certificates for Authentication on page 38 • Deploy Machine Certificates for Authentication on page 38 • Deploy User-Specific Client Certificates for Authentication on page 42 Deploy Shared Client Certificates for Authentication To confirm that an endpoint user belongs to your organization, you can use the same client certificate for all endpoints or generate separate certificates to deploy with a particular agent configuration. Use this workflow to issue self-signed client certificates for this purpose and deploy them from the portal. STEP 1 | Generate a certificate to deploy to multiple GlobalProtect clients. 1. Create the root CA certificate for issuing self-signed certificates for the GlobalProtect components. 2. Select Device > Certificate Management > Certificates > Device Certificates and then click Generate. 3. Use the Local certificate type (the default). 4. Enter a Certificate Name. This name cannot contain spaces. 5. In the Common Name field enter a name to identify this certificate as an agent certificate, for example GP_Windows_clients. Because this same certificate will be deployed to all agents using the same configuration, it does not need to uniquely identify a specific user or endpoint. 6. In the Signed By field, select your root CA. 7. Select an OCSP Responder to verify the revocation status of certificates. 8. Click OK to generate the certificate. STEP 2 | Set Up Two-Factor Authentication. Configure authentication settings in a GlobalProtect portal agent configuration to enable the portal to transparently deploy the client certificate that is Local to the firewall to clients that receive the configuration. Deploy Machine Certificates for Authentication To confirm that the endpoint belongs to your organization, use your own public-key infrastructure (PKI) to issue and distribute machine certificates to each endpoint (recommended) or generate a self-signed machine certificate for export. With the pre-logon connect methods, a machine certificate is required and must be installed on the endpoint before GlobalProtect components will grant access. To confirm that the endpoint belongs to your organization, you must also configure an authentication profile to authenticate the user. See Two-Factor Authentication. Use the following workflow to create the client certificate and manually deploy it to an endpoint. For more information, see About GlobalProtect User Authentication. For an example configuration, see Remote Access VPN (Certificate Profile). STEP 1 | Issue client certificates to GlobalProtect clients and endpoints. 38 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. This enables the GlobalProtect portal and gateways to validate that the device belongs to your organization. 1. Create the root CA certificate for issuing self-signed certificates for the GlobalProtect components. 2. Select Device > Certificate Management > Certificates > Device Certificates and then click Generate. 3. Enter a Certificate Name. The certificate name cannot contain any spaces. 4. Configure cryptographic settings for the certificate including the encryption Algorithm, key length (Number of Bits), Digest algorithm (use sha1, sha256, or sha384; sha512 is not supported with client certificates), and Expiration (in days) for the certificate. 5. 6. 7. 8. 9. If the firewall is in FIPS-CC mode and the key generation algorithm is RSA, the RSA keys must be 2,048 bits or 3072 bits. In the Certificate Attributes section, Add and define the attributes that uniquely identify the GlobalProtect clients as belonging to your organization. Keep in mind that if you add a Host Name attribute (which populates the SAN field of the certificate), it must be the same as the value you defined for the Common Name. In the Signed By field, select your root CA. Select an OCSP Responder to verify the revocation status of certificates. (Optional) In the Certificate Attributes section, click Add and define the attributes to identify the GlobalProtect clients as belonging to your organization if required as part of your security requirements. Click OK to generate the certificate. STEP 2 | Install certificates in the personal certificate store on the endpoints. If you are using unique user certificates or machine certificates, you must install each certificate in the personal certificate store on the endpoint prior to the first portal or gateway connection. Install machine certificates to the Local Computer certificate store on Windows and in the System Keychain on Mac OS. Install user certificates to the Current User certificate store on Windows and in the Keychain on Mac OS. For example, to install a certificate on a Windows system using the Microsoft Management Console: 1. From the command prompt, enter mmc to launch the console. 2. Select File > Add/Remove Snap-in. 3. Select Certificates, click Add and then select one of the following, depending on what type of certificate you are importing: • Computer account—Select this option if you are importing a machine certificate. • My user account—Select this option if you are importing a user certificate. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 39 2017 Palo Alto Networks, Inc. 4. Expand Certificates and select Personal and then in the Actions column select Personal > More Actions > All Tasks > Import and follow the steps in the Certificate Import Wizard to import the PKCS file you got from the CA. 5. Browse to the .p12 certificate file to import (select Personal Information Exchange as the file type to browse for) and enter the Password that you used to encrypt the private key. Select Personal as the Certificate store. STEP 3 | Verify that the certificate has been added to the personal certificate store. Navigate to the personal certificate store: 40 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. STEP 4 | Import the root CA certificate used to issue the client certificates onto the firewall. This step is required only if an external CA issued the client certificates, such as a public CA or an enterprise PKI CA. If you are using self-signed certificates, the root CA is already trusted by the portal and gateways. 1. Download the root CA certificate used to issue the client certificates (Base64 format). 2. Import the root CA certificate from the CA that generated the client certificates onto the firewall: 1. 2. 3. 4. 5. 6. 7. Select Device > Certificate Management > Certificates > Device Certificates and click Import. Use the Local certificate type (the default). Enter a Certificate Name that identifies the certificate as your client CA certificate. Browse to the Certificate File you downloaded from the CA. Select Base64 Encoded Certificate (PEM) as the File Format and then click OK. Select the certificate you just imported on the Device Certificates tab to open it. Select Trusted Root CA and then click OK. STEP 5 | Create a client certificate profile. 1. Select Device > Certificates > Certificate Management > Certificate Profile, click Add, and enter a profile Name. 2. Select a value for the Username Field to specify which field in the certificate will contain the user’s identity information. If you plan to configure the portal or gateways to authenticate users with certificates only, you must specify the Username Field. This enables GlobalProtect to associate a username with the certificate. If you plan to set up the portal or gateway for two-factor authentication, you can leave the default value of None, or, to add an additional layer of security, specify a username. If you specify a username, your external authentication service verifies that the username in the client certificate matches the username requesting authentication. This ensures that the user is the one to which the certificate was issued. Users cannot change the username that is included in the certificate. 3. In the CA Certificates field, click Add, select the Trusted Root CA certificate you imported in 4 and then click OK. STEP 6 | Save the configuration. Click Commit. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 41 2017 Palo Alto Networks, Inc. Deploy User-Specific Client Certificates for Authentication To authenticate individual users, you must issue a unique client certificate to each GlobalProtect user and deploy the client certificate to the endpoints prior to enabling GlobalProtect. To automate the generation and deployment of user-specific client certificates, you can configure your GlobalProtect portal to act as a Simple Certificate Enrollment Protocol (SCEP) client to a SCEP server in your enterprise PKI. SCEP operation is dynamic in that the enterprise PKI generates a user-specific certificate when the portal requests it and sends the certificate to the portal. The portal then transparently deploys the certificate to the client. When a user requests access, the agent or app can then present the client certificate to authenticate with the portal or gateway. The GlobalProtect portal or gateway uses identifying information about the device and user to evaluate whether to permit access to the user. GlobalProtect blocks access if the host ID is on a device block list or if the session matches any blocking options specified in a certificate profile. If client authentication fails due to an invalid SCEP-based client certificate, the GlobalProtect client tries to authenticate with the portal per the settings in the authentication profile and retrieve the certificate. If the client cannot retrieve the certificate from the portal, the device is not able to connect. STEP 1 | Create a SCEP profile. 1. Select Device > Certificate Management > SCEP and then Add a new profile. 2. Enter a Name to identify the SCEP profile. 3. If this profile is for a firewall with multiple virtual systems capability, select a virtual system or Shared as the Location where the profile is available. STEP 2 | (Optional) To make the SCEP-based certificate generation more secure, configure a SCEP challenge-response mechanism between the PKI and portal for each certificate request. After you configure this mechanism, its operation is invisible, and no further input from you is necessary. To comply with the U.S. Federal Information Processing Standard (FIPS), use a Dynamic SCEP challenge and specify a Server URL that uses HTTPS (see 7). Select one of the following options: • None—(Default) The SCEP server does not challenge the portal before it issues a certificate. • Fixed—Obtain the enrollment challenge password from the SCEP server in the PKI infrastructure and then enter the password into the Password field. • Dynamic—Enter a username and password of your choice (possibly the credentials of the PKI administrator) and the SCEP Server URL where the portal-client submits these credentials. The uses the credentials to authenticate with the SCEP server which transparently generates an OTP password for the portal upon each certificate request. (You can see this OTP change after a screen refresh in The enrollment challenge password is field after each certificate request.) The PKI transparently passes each new password to the portal, which then uses the password for its certificate request. STEP 3 | Specify the settings for the connection between the SCEP server and the portal to enable the portal to request and receive client certificates. You can include additional information about the client device or user by specifying tokens in the Subject name of the certificate. In the Subject field of the CSR to the SCEP server, the portal includes the token value as CN and HostID as SerialNumber. The host ID varies by device type: GUID (Windows) MAC address of the interface (Mac), Android ID (Android devices), UDID (iOS devices), or a unique name that GlobalProtect assigns (Chrome). 42 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. 1. Configure the Server URL that the portal uses to reach the SCEP server in the PKI (for example, http://10.200.101.1/certsrv/mscep/). 2. Enter a string (up to 255 characters in length) in the CA-IDENT Name field to identify the SCEP server. 3. Enter the Subject name to use in the certificates generated by the SCEP server. The subject must be a distinguished name in the = format and must include a common name (CN) attribute (CN= ). The CN supports the following dynamic tokens: • $USERNAME—Use this token to enable the portal to request certificates for a specific user. To use this variable, you must also Enable Group Mapping. The username entered by the user must match the name in the user-group mapping table. • $EMAILADDRESS—Use this token to request certificates associated with a specific email address. To use this variable, you must also Enable Group Mapping and configure the Mail Attributes in the Mail Domains section of the Server Profile. If GlobalProtect cannot identify an email address for the user, it generates a unique ID and populates the CN with that value. • $HOSTID—To request certificates for the device only, specify the host ID token. When a user attempts to log in to the portal, the endpoint sends identifying information that includes its host ID value. When the GlobalProtect portal pushes the SCEP settings to the agent, the CN portion of the subject name is replaced with the actual value (username, host ID, or email address) of the certificate owner (for example, O=acme,CN=johndoe). 4. Select the Subject Alternative Name Type: • RFC 822 Name—Enter the email name in a certificate’s subject or Subject Alternative Name extension. • DNS Name—Enter the DNS name used to evaluate certificates. • Uniform Resource Identifier—Enter the name of the resource from which the client will obtain the certificate. • None—Do not specify attributes for the certificate. STEP 4 | (Optional) Configure cryptographic settings for the certificate. • Select the key length (Number of Bits) for the certificate. If the firewall is in FIPS-CC mode and the key generation algorithm is RSA. The RSA keys must be 2,048 bits or larger. • Select the Digest for CSR which indicates the digest algorithm for the certificate signing request (CSR): sha1, sha256, or sha384. Sha512 is not supported as a digest algorithm for client certificates on GlobalProtect endpoints. STEP 5 | (Optional) Configure the permitted uses of the certificate, either for signing or encryption. • To use this certificate for signing, select the Use as digital signature check box. This enables the endpoint use the private key in the certificate to validate a digital signature. • To use this certificate for encryption, select the Use for key encipherment check box. This enables the client use the private key in the certificate to encrypt data exchanged over the HTTPS connection established with the certificates issued by the SCEP server. STEP 6 | (Optional) To ensure that the portal is connecting to the correct SCEP server, enter the CA Certificate Fingerprint. Obtain this fingerprint from the SCEP server interface in the Thumbprint field. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 43 2017 Palo Alto Networks, Inc. 1. Enter the URL for the SCEP server’s administrative UI (for example, http:// / CertSrv/mscep_admin/). 2. Copy the thumbprint and enter it in the CA Certificate Fingerprint field. STEP 7 | Enable mutual SSL authentication between the SCEP server and the GlobalProtect portal. This is required to comply with the U.S. Federal Information Processing Standard (FIPS). FIPS-CC operation is indicated on the firewall login page and in its status bar. Select the SCEP server’s root CA Certificate. Optionally, you can enable mutual SSL authentication between the SCEP server and the GlobalProtect portal by selecting a Client Certificate. STEP 8 | Save and commit the configuration. 1. Click OK to save the settings and close the SCEP configuration. 2. Commit the configuration. The portal attempts to request a CA certificate using the settings in the SCEP profile and saves it to the firewall hosting the portal. If successful, the CA certificate is shown in Device > Certificate Management > Certificates. STEP 9 | (Optional) If after saving the SCEP profile, the portal fails to obtain the certificate, you can manually generate a certificate signing request (CSR) from the portal. 1. Select Device > Certificate Management > Certificates > Device Certificates and then click Generate. 2. Enter a Certificate Name. This name cannot contain spaces. 3. Select the SCEP Profile to use to submit a CSR to your enterprise PKI. 4. Click OK to submit the request and generate the certificate. STEP 10 | Set Up Two-Factor Authentication. Assign the SCEP profile a GlobalProtect portal agent configuration to enable the portal to transparently request and deploy client certificates to clients that receive the configuration. 44 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. Set Up Two-Factor Authentication If you require strong authentication to protect sensitive assets or to comply with regulatory requirements, such as PCI, SOX, or HIPAA, configure GlobalProtect to use an authentication service that uses a two-factor authentication scheme. A two-factor authentication scheme requires two things: something the end user knows (such as a PIN or password) and something the end user has (a hardware or software token/OTP, smart card, or certificate). You can also enable two-factor authentication using a combination of external authentication services, and client and certificate profiles. The following topics provide examples for how to set up two-factor authentication on GlobalProtect: • Enable Two-Factor Authentication Using Certificate and Authentication Profiles on page 45 • Enable Two-Factor Authentication Using One-Time Passwords (OTPs) on page 47 • Enable Two-Factor Authentication Using Smart Cards on page 50 Enable Two-Factor Authentication Using Certificate and Authentication Profiles The following workflow describes how to configure GlobalProtect client authentication requiring the user to authenticate both to a certificate profile and an authentication profile. The user must successfully authenticate using both methods in order to connect to the portal/gateway. For more details on this configuration, see Remote Access VPN with Two-Factor Authentication. STEP 1 | Create an authentication server profile. The authentication server profile determines how the firewall connects to an external authentication service and retrieves the authentication credentials for your users. If you are using LDAP to connect to Active Directory (AD), you must create a separate LDAP server profile for every AD domain. Select Device > Server Profiles and a profile type (LDAP, Kerberos, RADIUS, or TACACS+). Add a new server profile. Enter a Profile Name for the profile, such as GP-User-Auth. (LDAP only) Select the Type of LDAP server (active-directory, e-directory, sun, or other). Click Add in the Servers list section and then enter the required information for connections to the authentication service, including the server Name, IP address or FQDN of the Server, and Port. 6. (RADIUS, TACACS+, and LDAP only) Specify settings to enable the firewall to authenticate to the authentication service as follows: 1. 2. 3. 4. 5. • RADIUS and TACACS+—Enter the shared Secret when adding the server entry. • LDAP—Enter the Bind DN and Password. 7. (LDAP only) If you want the endpoint to use SSL or TLS for a more secure connection with the directory server, select the Require SSL/TLS secured connection check box (selected by default). The protocol that the device uses depends on the server Port in the Server list: • 389 (default)—TLS (specifically, the device uses the StartTLS operation to upgrade the initial plaintext connection to TLS). • 636—SSL. • Any other port—The device first attempts to use TLS. If the directory server does not support TLS, the device uses SSL. 8. (LDAP only) For additional security, select the Verify Server Certificate for SSL sessions check box so that the endpoint verifies the certificate that the directory server presents for SSL/TLS connections. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 45 2017 Palo Alto Networks, Inc. To enable verification, you also must select the Require SSL/TLS secured connection check box. For verification to succeed, one of the following conditions must be true: • The certificate is in the list of device certificates: Device > Certificate Management > Certificates > Device Certificates. Import the certificate into the endpoint if necessary. • The certificate signer is in the list of trusted certificate authorities: Device > Certificate Management > Certificates > Default Trusted Certificate Authorities. 9. Click OK to save the server profile. STEP 2 | Create an authentication profile that identifies the service for authenticating users. (You later have the option of assigning the profile on the portal and on gateways.) 1. 2. 3. 4. 5. 6. 7. Select Device > Authentication Profile and Add a new profile. Enter a Name for the profile. Select the Location. Select the Type of Authentication (LDAP, Kerberos, RADIUS, or TACACS+). Select the Server Profile you created in 1. (LDAP only) Enter sAMAccountName as the Login Attribute. Click OK to save the authentication profile. STEP 3 | Create a client certificate profile that the portal uses to authenticate the client certificates that come from user devices. When you configure two-factor authentication to use client certificates, the external authentication service uses the username value to authenticate the user, if specified, in the client certificate. This ensures that the user who is logging is in is actually the user to whom the certificate was issued. 1. Select Device > Certificates > Certificate Management > Certificate Profile and click Add and enter a profile Name. 2. Select a value for the Username Field: • If you intend for the client certificate to authenticate individual users, select the certificate field that identifies the user. • If you are deploying the client certificate from the portal, leave this field set to None. • If you are setting up a certificate profile for use with a pre-logon connect method, leave the field set to None. 3. In the CA Certificates area, click Add and then: 1. Select the CA certificate, either a trusted root CA certificate or the CA certificate from a SCEP server. (If necessary, import the certificate). 2. (Optional) Enter the Default OCSP URL. 3. (Optional) Select a certificate for OCSP Verify CA. 4. (Optional) Select options that specify when to block the user’s requested session: 1. Status of certificate is unknown. 2. GlobalProtect component does not retrieve certificate status within the number of seconds in Certificate Status Timeout. 3. Serial number attribute in the subject of a client certificate does not match the host ID that the GlobalProtect agent reports for the client endpoint. 5. Click OK. STEP 4 | (Optional) Issue client certificates to GlobalProtect clients and endpoints. 46 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. To transparently deploy client certificates, configure your portal to distribute a shared client certificate to your endpoints or configure the portal to use SCEP to request and deploy unique client certificates for each user. 1. Use your enterprise PKI or a public CA to issue a client certificate to each GlobalProtect user. 2. For the pre-logon connect methods, install certificates in the personal certificate store on the client systems. STEP 5 | Save the GlobalProtect configuration. Click Commit. Enable Two-Factor Authentication Using One-Time Passwords (OTPs) Use this workflow to configure two-factor authentication using one-time passwords (OTPs) on the portal and gateways. When a user requests access, the portal or gateway prompts the user to enter an OTP. The authentication service sends the OTP as a token to the user’s RSA device. Setting up a two-factor authentication scheme is similar to setting up other types of authentication and requires you to configure: • A server profile (usually for a RADIUS service for two-factor authentication) assigned to an authentication profile. • A client authentication profile that includes the authentication profile for the service that these components use. By default, the agent supplies the same credentials it used to log in to the portal and to the gateway. In the case of OTP authentication, this behavior will cause the authentication to initially fail on the gateway and, because of the delay this causes in prompting the user for a login, the user’s OTP may expire. To prevent this, you must configure the portals and gateways that prompt for the OTP instead of using the same credentials on a per-agent configuration basis. You can also reduce the frequency in which users are prompted for OTPs by configuring an authentication override. This enables the portals and gateways to generate and accept a secure encrypted cookie to authenticate the user for a specified amount of time. The portals and/or gateways will not require a new OTP until the cookie expires thus reducing the number of times users must provide an OTP. STEP 1 | After you have configured the back-end RADIUS service to generate tokens for the OTPs and ensured users have any necessary devices (such as a hardware token), set up a RADIUS server to interact with the firewall. For specific instructions, refer to the documentation for your RADIUS server. In most cases, you need to set up an authentication agent and a client configuration on the RADIUS server to enable communication between the firewall and the RADIUS server. You also define the shared secret to use for encrypting sessions between the firewall and the RADIUS server. STEP 2 | On each firewall that hosts the gateways and/or portal, create a RADIUS server profile. (For a small deployment, one firewall can host the portal and gateways.) 1. 2. 3. 4. Select Device > Server Profiles > RADIUS. Add a new profile. Enter a Name for this RADIUS profile. In the Servers area, Add a RADIUS instance and enter: • A descriptive Name to identify this RADIUS server GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 47 2017 Palo Alto Networks, Inc. • The RADIUS Server IP address • The shared Secret for encrypting sessions between the firewall and the RADIUS server • The Port number on which the RADIUS server listens for authentication requests (default 1812) 5. Click OK to save the profile. STEP 3 | Create an authentication profile. Select Device > Authentication Profile. Add a new profile. Enter a Name for the profile. The name cannot contain spaces. Select RADIUS as the Type of authentication service. Select the Server Profile you created for accessing your RADIUS server. Enter the User Domain name. The firewall uses this value for matching authenticating users against Allow List entries and for User-ID group mapping. 7. Select a Username Modifier to modify the username/domain format expected by the RADIUS server. 8. Click OK to save the authentication profile. 1. 2. 3. 4. 5. 6. STEP 4 | Assign the authentication profile to the GlobalProtect gateway(s) and/or portal. You can configure multiple Client Authentication configurations for the portal and gateways. For each Client Authentication configuration you can specify the authentication profile to apply to endpoints of a specific OS. This step describes only how to add the authentication profile to the gateway or portal configuration. For additional details on setting up these components, see GlobalProtect Gateways and GlobalProtect Portals. 1. Select Network > GlobalProtect > Gateways and an existing gateway configuration by name (or Add one). If you are adding a new gateway, specify its name, location, and network parameters. 2. On the Authentication tab, select an SSL/TLS service profile or Add a new profile. 3. Add a Client Authentication configuration and enter its Name. 4. Select the endpoint OS to which this configuration applies. 5. Select the Authentication Profile you created in Create an authentication profile. 6. (Optional) Enter a custom authentication message. 7. To add additional Client Authentication configurations, repeat steps c through f. 8. Click OK to save the configuration. 9. To add other gateways, repeat steps b through h. 10.To assign the authentication profile to the portal, select Network > GlobalProtect > Portals and repeat steps b through h. STEP 5 | (Optional) Configure the portal or gateways to prompt for a username and password or only a password each time the user logs in. Saving the password is not supported with two-factor authentication using OTPs because the user must enter a dynamic password each time they log in. This step describes only how to configure the password setting in a portal agent configuration. For additional details, see Customize the GlobalProtect Agent. Select Network > GlobalProtect > Portals and select an existing portal configuration. Select Agent. Select an existing agent configuration or Add one. Set Save User Credentials to Save Username Only or No. This setting enables GlobalProtect to prompt for dynamic passwords for each component you select in the following step. 5. Click OK twice to save the configuration. 1. 2. 3. 4. 48 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. STEP 6 | Select the GlobalProtect components—portal and types of gateways—that prompt for dynamic passwords, such as OTPs, instead of using saved credentials. Select Network > GlobalProtect > Portals and select an existing portal configuration. Select Agent. Select an existing agent configuration or Add one. Select the Authentication tab, and then select the Components that Require Dynamic Passwords (Two-Factor Authentication). When selected, the portal and/or types of gateways prompt for OTPs. 5. Click OK twice to save the configuration. 1. 2. 3. 4. STEP 7 | If single sign-on (SSO) is enabled, disable it. The agent configuration specifies RADIUS as the authentication service so Kerberos SSO is not supported. This step describes only how to disable SSO. For more details, see Define the GlobalProtect Agent Configurations. 1. 2. 3. 4. 5. Select Network > GlobalProtect > Portals and select the portal configuration. Select Agent and then select the agent configuration (or Add one). Select the App tab. Set Use Single Sign-on to No. Click OK twice to save the configuration. STEP 8 | (Optional) To minimize the number of times a user must provide credentials, configure an authentication override. By default, the portal or gateways authenticate the user with an authentication profile and optional certificate profile. With authentication override, the portal or gateway authenticates the user with an encrypted cookie that it has deployed to the endpoint. While the cookie is valid, the user can log in without entering regular credentials or an OTP. For more information, see Cookie Authentication on the Portal or Gateway. If you need to immediately block access to a device whose cookie has not yet expired (for example, if the device is lost or stolen), you can Block Device Access by adding the device to a block list. For more details, see GlobalProtect Gateways and GlobalProtect Portals. 1. Select Network > GlobalProtect > Gateways or Portals and select the configuration (or Add one). 2. Select Agent > Client Settings (on the gateway) or Agent (on the portal) and then select the configuration (or Add one). 3. In the Authentication Override area, configure the following: • Generate cookie for authentication override—Enable the portal or gateway to generate encrypted, endpoint-specific cookies. After users successfully authenticate, the portal or gateway issue the authentication cookie to the endpoint. • Accept cookie for authentication override—Select the check box to instruct the portal or gateway to authenticate the user through a valid, encrypted cookie. When the endpoint presents a valid cookie, the portal or gateway verifies that the cookie was encrypted by the portal or gateway, decrypts the cookie, and then authenticates the user. • Cookie Lifetime—Specify the hours, days, or weeks that the cookie is valid. Typical lifetime is 24 hours for gateways—which protect sensitive information—or 15 days for the portal. The range for hours is 1–72; for weeks, 1–52; and for days, 1–365. After the cookie expires on either the portal or gateway (whichever occurs first), the portal or gateway prompts the user to authenticate and subsequently encrypts a new cookie to send to the endpoint. • Certificate to Encrypt/Decrypt Cookie—Select the RSA certificate to use to encrypt and decrypt the cookie. You must use the same certificate on the portal and gateways. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 49 2017 Palo Alto Networks, Inc. As a best practice, configure the RSA certificate to use the strongest digest algorithm that your network supports. The portal and gateways use the RSA encrypt padding scheme PKCS#1 V1.5 to generate the cookie (using the public key of the certificate) and decrypt the cookie (using the private key of the certificate). 4. Click OK twice to save the configuration. STEP 9 | Commit the configuration. Click Commit. STEP 10 | Verify the configuration. The gateway and portal must be configured before you take his step. For details on setting up these components, see GlobalProtect Gateways and GlobalProtect Portals. From an endpoint running the GlobalProtect agent, try to connect to a gateway or portal on which you enabled OTP authentication. You should see two prompts similar to the following: The first prompt requests a PIN (either a user- or system-generated PIN): The second prompt requests your token or OTP: Enable Two-Factor Authentication Using Smart Cards If you want to enable your end users to authenticate using a smart card or common access card (CAC), you must import the Root CA certificate that issued the certificates contained on the end user CAC or smart 50 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. cards onto the portal and gateway. You can then create a certificate profile that includes that Root CA and apply it to your portal and/or gateway configurations to enable use of the smart card in the authentication process. STEP 1 | Set up your smart card infrastructure. This procedure assumes that you have deployed smart cards and smart card readers to your end users. For specific instructions, refer to the documentation for the user authentication provider software. In most cases, setting up the smart card infrastructure involves the generating of certificates for end users and for the participating servers, which are the GlobalProtect portal and gateway(s) in this use case. STEP 2 | Import the Root CA certificate that issued the client certificates contained on the end user smart cards. Make sure the certificate is accessible from your management system and then complete the following steps: 1. 2. 3. 4. Select Device > Certificate Management > Certificates > Device Certificates. Click Import and enter a Certificate Name. Enter the path and name to the Certificate File received from the CA, or Browse to find the file. Select Base64 Encoded Certificate (PEM) as the File Format and then click OK to import the certificate. STEP 3 | Create the certificate profile on each portal/gateway on which you plan to use CAC or smart card authentication. For details on other certificate profile fields, such as whether to use CRL or OCSP, refer to the online help. 1. Select Device > Certificate Management > Certificate Profile and click Add and enter a profile Name. 2. In the Username field, select the certificate field that PAN-OS uses to match the IP address for UserID, either Subject to use a common name, Subject Alt: Email to use an email address, or Subject Alt: Principal Name to use the Principal Name. 3. In the CA Certificates field, click Add, select the trusted root CA Certificate you imported in 2 and then click OK. 4. Click OK to save the certificate profile. STEP 4 | Assign the certificate profile to the gateway(s) or portal. This section describes only how to add the certificate profile to the gateway or portal configuration. For details on setting up these components, see GlobalProtect Gateways and GlobalProtect Portals. 1.

Configure GlobalProtect to Facilitate MultiFactor Authentication Notifications To protect critical applications and stop attackers from using stolen credentials to conduct lateral movement throughout your network, you can configure policy-based multi-factor authentication (MFA). This ensures that each user responds to multiple authentication challenges of different types (factors) before they can access highly sensitive services and applications. If a user session matches the Authentication policy, the type of application or service determines the user experience for notifications about the authentication challenge: • (Windows or Mac endpoints only) Non-browser-based applications—To facilitate MFA notifications for non-HTTP applications (such as Perforce) on Windows or Mac endpoints, a GlobalProtect client is required. When a session matches an Authentication policy rule, the firewall sends a UDP notification to the GlobalProtect client with an embedded URL link to the Authentication Portal page. The GlobalProtect client then displays this message as a pop up notification to the user. • Browser-based applications—Browser-based applications do not require GlobalProtect to display notification messages to the user. When the firewall identifies a session as web-browsing traffic (based on App-ID), the firewall automatically presents the user with Authentication Portal page (previously called the Captive Portal page) specified in the Authentication policy rule. For more information, see Configure Multi-Factor Authentication. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 59 2017 Palo Alto Networks, Inc. To configure GlobalProtect to display MFA notifications for non-browser-based applications, use the following workflow: STEP 1 | Before you configure GlobalProtect, configure multi-factor authentication on the firewall. If you are using two-factor authentication with GlobalProtect to authenticate to the gateway or portal, a RADIUS server profile is required. If you are using GlobalProtect to notify the user about an authentication policy match (UDP message), a Multi Factor Authentication server profile is sufficient. To use multi-factor authentication for protecting sensitive resources, the easiest solution is to integrate the firewall with an MFA vendor that is already established in your network. When your MFA structure is ready, you can start configuring the components of your authentication policy. For more information, refer to Configure Multi-Factor Authentication. • Enable Captive Portal to record authentication timestamps and update user mappings. • Create server profiles that define how the firewall will connect to the services that authenticate users. • Assign the server profiles to an Authentication profile which specifies authentication parameters. • Configure a Security policy rule that allows users to access the resources that require authentication. STEP 2 | (External gateways only) For GlobalProtect to support multi-factor authentication on external gateways, you must Configure a response page for the ingress tunnel interface on the firewall: 1. Select Device > Response Pages > MFA Login Page. 2. Select and then Export the Predefined template to a location of your choice. 3. On your client system, use an HTML editor to customize the downloaded response page and save it with a unique filename. 4. Return to the MFA Login Page dialog on the firewall, Import your customized page, Browse to select the Import File, select the Destination (virtual system or shared location), click OK, and click Close. STEP 3 | (External gateways only) Enable Response Pages as a permitted service on the Interface Mgmt profile: 1. Select Network > Network Profiles > Interface Mgmt and then select the profile. 2. In the Permitted Services area, select Response Pages and click OK. STEP 4 | (External gateways only) Attach the Interface Mgmt profile to a tunnel interface: 1. Select Network > Interfaces > Tunnel, and the tunnel interface on which you want to use the response page. 2. Select Advanced, and then select the Interface Mgmt profile you configured in the previous step as the Management Profile. STEP 5 | (External gateways only) Enable User Identification on the Zone associated with the tunnel interface (Network > Zones > GlobalProtect > Portals and select a portal configuration (or Add one). 2. Select Agent and then select an existing agent configuration or Add one. 3. In the App tab, specify the following: • Set Enable Inbound Authentication Prompts from MFA Gateways to Yes. To support multifactor authentication (MFA), a GlobalProtect client must receive and acknowledge UDP prompts that are inbound from the gateway. Select Yes to enable a GlobalProtect client to receive and 60 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. acknowledge the prompt. By default, the value is set to No meaning GlobalProtect will block UDP prompts from the gateway. • In Network Port for Inbound Authentication Prompts (UDP), specify the port number a GlobalProtect client uses to receive inbound authentication prompts from MFA gateways. The default port is 4501. To change the port, specify a number from 1 to 65535. • In Trusted MFA Gateways, specify the list of authentication gateways a GlobalProtect client will trust for multi-factor authentication. When a GlobalProtect client receives a UDP message on the specified network port, GlobalProtect displays an authentication message only if the UDP prompt comes from a trusted gateway. • Configure the Default Message for Inbound Authentication Prompts. When users try to access a resource that requires additional authentication, GlobalProtect receives a UDP packet containing the inbound authentication prompt and displays this message. The UDP packet also contains the URL for the Authentication Portal page you specified in Configure Multi-Factor Authentication. GlobalProtect automatically appends the URL to the message. For example, to display the notification shown in the beginning of this topic enter the following message: You have attempted to access a protected resource that requires additional authentication. Proceed to authenticate at: 4. Save the agent configuration (click OK twice), and then Commit your changes. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 61 2017 Palo Alto Networks, Inc. Enable Delivery of GlobalProtect Client VSAs to a RADIUS Server When communicating with GlobalProtect portals or gateways, GlobalProtect clients send information that includes the client IP address, operating system (OS), hostname, user domain, and GlobalProtect agent/app version. You can enable the firewall to send this information as Vendor-Specific Attributes (VSAs) to a RADIUS server during authentication (by default, the firewall does not send the VSAs). RADIUS administrators can then perform administrative tasks based on those VSAs. For example, RADIUS administrators might use the client OS attribute to define a policy that mandates regular password authentication for Microsoft Windows users and one-time password (OTP) authentication for Google Android users. The following are prerequisites for this procedure: • Import the Palo Alto Networks RADIUSdictionary into your RADIUS server. • Configure a RADIUS server profile and assign it to an authentication profile: see Set Up External Authentication. • Assign the authentication profile to a GlobalProtect portal or gateway: see Set Up Access to the GlobalProtect Portal or Configure a GlobalProtect Gateway. STEP 1 | Log in to the firewall CLI. STEP 2 | Enter the command for each VSA you want to send. username@hostname> username@hostname> username@hostname> username@hostname> username@hostname> set set set set set authentication authentication authentication authentication authentication radius-vsa-on radius-vsa-on radius-vsa-on radius-vsa-on radius-vsa-on client-source-ip client-os client-hostname user-domain client-gp-version If you later want to stop the firewall from sending particular VSAs, run the same commands but use the radius-vsa-off option instead of radius-vsa-on. 62 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 2017 Palo Alto Networks, Inc. Enable Group Mapping Because the agent or app running on your end-user systems requires the user to successfully authenticate before being granted access to GlobalProtect, the identity of each GlobalProtect user is known. However, if you want to be able to define GlobalProtect configurations and/or security policies based ongroup membership, the firewall must retrieve the list of groups and the corresponding list of members from your directory server. This is known as group mapping. To enable this functionality, you must create an LDAP server profile that instructs the firewall how to connect and authenticate to the directory server and how to search the directory for the user and group information. After the firewall connects to the LDAP server and retrieves the group mappings, you can select groups when you define the agent configurations and security policies. The firewall supports a variety of LDAP directory servers, including Microsoft Active Directory (AD), Novell eDirectory, and Sun ONE Directory Server. Use the following procedure to connect to your LDAP directory to enable the firewall to retrieve user-togroup mapping information: STEP 1 | Create an LDAP Server Profile that specifies how to connect to the directory servers to which the firewall should connect to obtain group mapping information. 1. Select Device > Server Profiles > LDAP and click Add. 2. Enter a Profile Name to identify the server profile. 3. If this profile is for a firewall with multiple virtual systems capability, select a virtual system or Shared as the Location where the profile is available. 4. For each LDAP server (up to four), Add and enter a Name (to identify the server), server IP address (LDAP Server field), and server Port (default 389). 5. Select the server Type from the drop-down: active-directory, e-directory, sun, or other. 6. If you want the device to use SSL or TLS for a more secure connection with the directory server, select the Require SSL/TLS secured connection check box (it is selected by default). The protocol that the device uses depends on the server Port: • 389 (default)—TLS (Specifically, the device uses the StartTLS operation, which upgrades the initial plaintext connection to TLS.) • 636—SSL • Any other port—The device first attempts to use TLS. If the directory server doesn’t support TLS, the device falls back to SSL. 7. For additional security, you can select the Verify Server Certificate for SSL sessions check box (it is cleared by default) so that the device verifies the certificate that the directory server presents for SSL/TLS connections. To enable verification, you also have to select the Require SSL/TLS secured connection check box. For verification to succeed, the certificate must meet one of the following conditions: • It is in the list of device certificates: Device > Certificate Management > Certificates > Device Certificates. Import the certificate into the device, if necessary. • The certificate signer is in the list of trusted certificate authorities: Device > Certificate Management > Certificates > Default Trusted Certificate Authorities. 8. Click OK. STEP 2 | Add the LDAP server profile to the User-ID Group Mapping configuration. 1. Select Device > User Identification > Group Mapping Settings and click Add. 2. Enter a Name for the configuration. 3. Select the Server Profile you just created. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication © 63 2017 Palo Alto Networks, Inc. 4. Make sure the Enabled check box is selected. STEP 3 | (Optional) Limit which groups can be selected in policy rules. By default, if you don’t specify groups, all groups are available in policy rules. 1. Add existing groups from the directory service: 1. Select the Group Include List tab. 2. In the Available Groups list, select the groups you want to appear in policy rules and click the Add icon . 2. If you want to base policy rules on user attributes that don’t match existing user groups, create custom groups based on LDAP filters: 1. Select the Custom Group tab and click Add. 2. Enter a group Name that is unique in the group mapping configuration for the current firewall or virtual system. If the Name has the same value as the Distinguished Name (DN) of an existing AD group domain, the firewall uses the custom group in all references to that name (for example, in policies and logs). 3. Specify an LDAP Filter of up to 2,048 UTF-8 characters, then click OK. The firewall doesn’t validate LDAP filters. To optimize LDAP searches and minimize the performance impact on the LDAP directory server, use indexed attributes and reduce the search scope to include the user and group objects that you require for policy or visibility. Alternatively, you can create custom groups based on LDAP filters. STEP 4 | Commit your changes. Click OK and Commit. 64 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Authentication GlobalProtect Gateways > GlobalProtect Gateway Concepts > Prerequisite Tasks for Configuring the GlobalProtect Gateway > Configure a GlobalProtect Gateway 65 66 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 2017 Palo Alto Networks, Inc. GlobalProtect Gateways Overview Because the GlobalProtect™ configuration that the portal delivers to the agents includes the list of gateways the client can connect to, it is a good idea to configure the gateways before configuring the portal. The GlobalProtect Gateways can be configured to provide two main functions: • Enforce security policy for the GlobalProtect agents and apps that connect to it. You can also enable HIP collection on the gateway for enhanced security policy granularity. For more information on enabling HIP checks, see Host Information. • Provide virtual private network (VPN) access to your internal network. VPN access is provided through an IPSec or SSL tunnel between the client and a tunnel interface on the gateway firewall. You can also configure GlobalProtect gateways on VM-Series firewalls deployed in the AWS cloud. By deploying the VM-Series firewall in the AWS cloud you can quickly and easily deploy GlobalProtect gateways in any region without the expense or IT logistics that are typically required to set up this infrastructure using your own resources. For details, see Use Case: VM-Series Firewalls as GlobalProtect Gateways in AWS. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 67 2017 Palo Alto Networks, Inc. GlobalProtect Gateway Concepts These sections provide information about gateway connection priority in a multiple gateway configuration and MIB support for GlobalProtect gateways. • Types of Gateways on page 68 • Gateway Priority in a Multiple Gateway Configuration on page 68 • GlobalProtect MIB Support on page 69 Types of Gateways GlobalProtect gateways provide security enforcement for traffic from GlobalProtect agents/apps. Additionally, if the HIP feature is enabled, the gateway generates a HIP report from the raw host data the clients submit and can use this information in policy enforcement. You Configure a GlobalProtect Gateway on an interface on any Palo Alto Networks next-generation firewall. You can run both a gateway and a portal on the same firewall, or you can have multiple, distributed gateways throughout your enterprise. You can configure any of the following types of gateways: • Internal—An internal gateway is an interface on the internal network configured as a GlobalProtect gateway for applying security policy for access to internal resources. When used in conjunction with User-ID and/or HIP checks, an internal gateway can be used to provide a secure, accurate method of identifying and controlling traffic by user and/or device state. Internal gateways are useful in sensitive environments where authenticated access to critical resources is required. You can configure an internal gateway in either tunnel mode or non-tunnel mode. An agent connects to the internal gateway after performing internal host detection to determine the location of the endpoint. • External gateway (auto discovery)—An external gateway resides outside of the corporate network and provides security enforcement and/or virtual private network (VPN) access for your remote users. The agent automatically connects to the external gateway depending on the priority you assign to the gateway, source region, and the response time (see Gateway Priority in a Multiple Gateway Configuration). When you configure an external gateway in the GlobalProtect portal agent configuration, auto discovery is the default. See Define the GlobalProtect Agent Configurations. • External gateway (manual)—A manual external gateway also resides outside of the corporate network and provides security enforcement and/or VPN access for your remote users. The difference between the auto-discovery external gateway and the manual external gateway is that the GlobalProtect agent only connects to a manual external gateway when the user initiates a connection. You can also configure different authentication requirements for manual external gateways. To configure a manual gateway, you must identify the gateway as Manual in the GlobalProtect portal agent configuration. See Define the GlobalProtect Agent Configurations. Gateway Priority in a Multiple Gateway Configuration To enable secure access for your mobile workforce no matter where they are located, you can strategically deploy additional Palo Alto Networks next-generation firewalls and configure them as GlobalProtect gateways. To determine the preferred gateway to which your agents connect, add the gateways to a portal agent configuration and assign each gateway a connection priority. See Define the GlobalProtect Agent Configurations on page 86. If a GlobalProtect portal agent configuration contains more than one gateway, the agent will attempt to communicate with all gateways listed in its agent configuration. The agent will then use priority and response time as to determine the gateway to which to connect. With GlobalProtect agent 4.0.2 and earlier releases, the agent connects to a lower priority gateway only if the response time for the higher priority gateway is greater than the average response time across all gateways. 68 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 2017 Palo Alto Networks, Inc. For example, consider the following response times for gw1 and gw2: Name Priority Response Time gw1 Highest 80 ms gw2 High 25 ms The agent determines that the response time for the gateway with the highest priority (higher number) is greater than the average response time for both gateways (52.5 ms) and, as a result, connects to gw2. In this example, the agent did not connect to gw1 even though it had a higher priority because a response time of 80 ms was higher than the average for both. Now consider the following response times for gw1, gw2, and a third gateway, gw3: Name Priority Response Time gw1 Highest 30 ms gw2 High 25 ms gw3 Medium 50 ms In this example, the average response time for all gateways is 35 ms. The agent would then evaluate which gateways responded faster than the average response time and see that gw1 and gw2 both had faster response times. The agent would then connect to whichever gateway had the highest priority. In this example, the agent connects to gw1 because gw1 has the highest priority of all the gateways with response times below the average. In addition to gateway priority, you add one or more source regions to an external gateway configuration, GlobalProtect recognizes the device region and only allows uses to connect to gateways that are configured for that region. For gateway choices, source region is considered first, then gateway priority. In GlobalProtect agent 4.0.3 and later releases, the GlobalProtect agent prioritizes the gateways assigned highest, high, and medium priority ahead of gateways assigned a low or lowest priority regardless of response time. The GlobalProtect agent then appends any gateways assigned a low or lowest priority to the list of gateways. This ensures that the agent first attempts to connect to the gateways that you configure with a higher priority. GlobalProtect MIB Support Palo Alto Networks devices support standard and enterprise management information bases (MIBs) that enable you to monitor the device’s physical state, utilization statistics, traps, and other useful information. Most MIBs use object groups to describe characteristics of the device using the Simple Network Management Protocol (SNMP) Framework. You must load these MIBs into your SNMP manager to monitor the objects (device statistics and traps) that are defined in the MIBs (for details, see Use an SNMP Manager to Explore MIBs and Objects in the PAN-OS 8.0 Administrator’s Guide). The PAN-COMMON-MIB—which is included with the enterprise MIBs—uses the panGlobalProtect object group. The following table describes the objects that make up the panGlobalProtect object group. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 69 2017 Palo Alto Networks, Inc. Object Description panGPGWUtilizationPct Utilization (as a percentage) of the GlobalProtect gateway panGPGWUtilizationMaxTunnels Maximum number of tunnels allowed panGPGWUtilizationActiveTunnelsNumber of active tunnels Use these SNMP objects to monitor utilization of GlobalProtect gateways and make changes as needed. For example, if the number of active tunnels reaches 80% or is higher than the maximum number of tunnels allowed, you should consider adding additional gateways. 70 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 2017 Palo Alto Networks, Inc. Prerequisite Tasks for Configuring the GlobalProtect Gateway Before you can configure the GlobalProtect gateway, you must have completed the following tasks: Created the interfaces (and zones) for the interface where you plan to configure each gateway. For gateways that require tunnel connections you must configure both the physical interface and the virtual tunnel interface. See Create Interfaces and Zones for GlobalProtect on page 15. Set up the gateway server certificates and SSL/TLS service profile required for the GlobalProtect agent to establish an SSL connection with the gateway. See Enable SSL Between GlobalProtect Components on page 17. Defined the authentication profiles and/or certificate profiles that will be used to authenticate GlobalProtect users. See Authentication on page 25. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 71 2017 Palo Alto Networks, Inc. Configure a GlobalProtect Gateway After you have completed the prerequisite tasks, configure the GlobalProtect Gateways: STEP 1 | Add a gateway. 1. Select Network > GlobalProtect > Gateways and click Add. 2. In the General screen, enter a Name for the gateway. The gateway name should have no spaces and, as a best practice, should include the location or other descriptive information to help users and administrators identify the gateway. 3. (Optional) Select the virtual system to which this gateway belongs from the Location field. STEP 2 | Specify the network information that enables clients to connect to the gateway. If you haven’t created the network interface for the gateway, see Create Interfaces and Zones for GlobalProtect for instructions. Do not attach an interface management profile that allows HTTP, HTTPS, Telnet, or SSH on the interface where you have configured a GlobalProtect portal or gateway because this enables access to your management interface from the Internet. Follow the Best Practices for Securing Administrative Access to ensure that you are securing administrative access to your firewalls in a way that will prevent successful attacks. 1. Select the Interface that clients will use for communication with the gateway. 2. Specify the IP Address Type and IP address for the gateway web service: • The IP address type can be IPv4 (for IPv4 traffic only), IPv6 (for IPv6 traffic only, or IPv4 and IPv6. Use IPv4 and IPv6 if your network supports dual stack configurations, where IPv4 and IPv6 run at the same time. • The IP address must be compatible with the IP address type. For example, 172.16.1/0 for IPv4 addresses or 21DA:D3:0:2F3B for IPv6 addresses. For dual stack configurations, enter both an IPv4 and IPv6 address. 3. Click OK to save changes. STEP 3 | Specify how the gateway authenticates users. If you haven’t created an SSL/TLS service profile for the gateway, see Deploy Server Certificates to the GlobalProtect Components. If you haven’t set up the authentication profiles or certificate profiles, see Authentication for instructions. Select Authentication and then configure any of the following: • To secure communication between the gateway and the agents, select the SSL/TLS Service Profile for the gateway. To provide the strongest security, set the Min Version of the SSL/TLS service profile to TLSv1.2. • To authenticate users with a local user database or an external authentication service, such as LDAP, Kerberos, TACACS+, SAML, or RADIUS (including OTP), Add a Client Authentication configuration with the following settings: • Enter a Name to identify the client authentication configuration. 72 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 2017 Palo Alto Networks, Inc. • Identify the type of client to which this configuration applies. By default, the configuration applies to Any client, but you can customize the type of endpoint by OS (Android, Chrome, iOS, Mac, Windows, or WindowsUWP) or by third-party IPSec VPN clients (X-Auth). • Select or add an Authentication Profile to authenticate an endpoint seeking access to the gateway. • Enter an Authentication Message to help end users understand which credentials to use when logging in. The message can be up to 100 characters in length (default is Enter login credentials). • To authenticate users based on a client certificate or a smart card/CAC, select the corresponding Certificate Profile. • To use two-factor authentication, select both an authentication profile and a certificate profile. Keep in mind that the user must successfully authenticate using both methods to be granted access. STEP 4 | Enable tunneling and configure the tunnel parameters. The tunnel parameters are required if you are setting up an external gateway. If you are configuring an internal gateway, they are optional. If you want to force use of SSL-VPN tunnel mode, clear the Enable IPSec check box. By default, SSL-VPN will only be used if the endpoint fails to establish an IPSec tunnel. Extended authentication (X-Auth) is only supported on IPSec tunnels. If you Enable X-Auth Support, GlobalProtect IPSec Crypto profiles are not applicable. For more information on supported cryptographic algorithms, see Reference: GlobalProtect Agent Cryptographic Functions. On the GlobalProtect Gateway Configuration dialog, select Agent > Tunnel Settings. Select the Tunnel Mode check box to enable tunneling. Select the Tunnel Interface you defined in 2 in Create Interfaces and Zones for GlobalProtect. (Optional) Specify Max User for the maximum number of users that can access the gateway at the same time for authentication, HIP updates, and GlobalProtect agent updates (range varies based on the platform and is displayed when the field is empty). 5. Select a GlobalProtect IPSec Crypto profile to secure the VPN tunnels between GlobalProtect agents and gateways. The default profile uses AES-128-CBC encryption and sha1 authentication. 1. 2. 3. 4. You can also create a new IPSec crypto profile. To create a new profile, select New GlobalProtect IPSec Crypto in the same drop-down and configure the following: 1. Enter a Name to identify the profile. 2. Add the Authentication and Encryption algorithms that the VPN peers can use to negotiate the keys for securing the data in the tunnel: • Encryption—If you are not certain of what the VPN peers support, you can add multiple encryption algorithms in top-to-bottom order of most-to-least secure, as follows: aes-256gcm, aes-128-gcm, aes-128-cbc. The peers negotiate the strongest algorithm to establish the tunnel. • Authentication—Select the authentication algorithm (sha1) to provide data integrity and authenticity protection. Although the authentication algorithm is required for the profile, this setting only applies to the AES-CBC cipher (aes-128-cbc). If you use an AES-GCM encryption algorithm (aes-256-gcm or aes-128-gcm), the setting is ignored because these ciphers natively provide ESP integrity protection. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 73 2017 Palo Alto Networks, Inc. 3. Click OK to save the profile. 6. (Optional) Select Enable X-Auth Support if any endpoint needs to connect to the gateway by using a third-party VPN (for example, a VPNC client running on Linux). If you enable X-Auth, you must provide the Group name and Group Password if the endpoint requires it. By default, the user is not required to re-authenticate if the key used to establish the IPSec tunnel expires. To require users to re-authenticate, clear the option to Skip Auth on IKE Rekey. Although X-Auth access is supported on iOS and Android endpoints, it provides limited GlobalProtect functionality on these endpoints. Instead, use the GlobalProtect app for simplified access to all the security features that GlobalProtect provides on iOS and Android endpoints. The GlobalProtect app for iOS is available at the Apple App Store. The GlobalProtect app for Android is available at Google Play. STEP 5 | (Optional) Modify the default timeout settings for endpoints. On the GlobalProtect Gateway Configuration dialog, select Agent > Timeout Settings and then configure the following settings: • Modify the maximum Login Lifetime for a single gateway login session. The default login lifetime is 30 days—during the lifetime, the user stays logged in as long as the gateway receives a HIP check from the endpoint within the Inactivity Logout period. After this time, the login session automatically logs out. • Modify the amount of time after which an inactive session is automatically logged out. The default Inactivity Logout period is 3 hours. A user is logged out of GlobalProtect if the gateway does not receive a HIP check from the endpoint during the configured amount of time. • Modify the number of minutes after which idle users are logged out of GlobalProtect. The default period for Disconnect on Idle is 180 minutes. Users are logged out of GlobalProtect if the GlobalProtect agent has not routed traffic through the VPN tunnel in the configured amount of time. This setting applies to GlobalProtect agents that use the on-demand connect method only. STEP 6 | (Optional) Configure authentication override settings to enable the gateway to generate and accept secure, encrypted cookies to authenticate the user. This capability allows the user to provide login credentials only once during a specified period of time (for example, every 24 hours). By default, a gateway authenticates the user with an authentication profile and optional certificate profile. When authentication override is enabled, GlobalProtect caches the result of a successful login and uses the cookie to authenticate the user instead of prompting the user for credentials. For more information, see Cookie Authentication on the Portal or Gateway. If client certificates are required, the endpoint must also provide a valid certificate to be granted access. In the event that you need to immediately block access to a device whose cookie has not yet expired (for example, if the device is lost or stolen), you can immediately Block Device Access by adding the device to a block list. 1. 2. 3. 4. On the GlobalProtect Gateway Configuration dialog, select Agent > Client Settings. Add a new agent configuration or select an existing configuration. Enter a Name to identify the agent configuration. Configure the following settings in the Authentication Override section: • Generate cookie for authentication override—Enable the gateway to generate encrypted, endpoint-specific cookies and issue the authentication cookies to the endpoint. • Accept cookie for authentication override—Enable the gateway to authenticate users with a valid, encrypted cookie. When the agent presents a valid cookie, the gateway verifies that the cookie was encrypted by the portal or gateway, decrypts the cookie, and then authenticates the user. 74 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 2017 Palo Alto Networks, Inc. • Cookie Lifetime—Specify the hours, days, or weeks that the cookie is valid. Default is 24 hours. The range for hours is 1–72; for weeks, 1–52; and for days, 1–365. After the cookie expires, the user must enter login credentials, and the gateway subsequently encrypts a new cookie to send to the agent. This value can be the same as or different from the Cookie Lifetime you configure for the portal. • Certificate to Encrypt/Decrypt Cookie—Select the RSA certificate to use to encrypt and decrypt the cookie. You must use the same certificate on the portal and gateways. As a best practice, configure the RSA certificate to use the strongest digest algorithm that your network supports. The portal and gateways use the RSA encrypt padding scheme PKCS#1 V1.5 to generate the cookie (using the public key of the certificate) and decrypt the cookie (using the private key of the certificate). STEP 7 | Configure the user or user group and the endpoint OS to which the agent configuration applies. The gateway uses the user/user group settings you specify to determine which configuration to deliver to the GlobalProtect agents that connect. Therefore, if you have multiple configurations, you must make sure to order them properly. As soon as the gateway finds a match, it will deliver the configuration. Therefore, more specific configurations must precede more general ones. See 10 for instructions on ordering the list of agent configurations. Network settings are not required in internal gateway configurations in non-tunnel mode, because agents use the network settings assigned to the physical network adapter. In a gateway agent configuration, select the User/User Group tab and configure the following settings: • To deliver this configuration to agents or apps running on specific operating system, Add the OS (Android, Chrome, iOS, Mac, Windows, or WindowsUWP) to which this configuration applies. Or leave the value in this section set to Any to deploy the configuration based on user/group only. • To restrict this configuration to a specific user and/or group, click Add in the User/User Group section of the window and then select the user or group you want to receive this configuration from the drop-down. Repeat this step for each user/group you want to add. Before you can restrict the configuration to specific groups, you must map users to groups as described in Enable Group Mapping. • To restrict the configuration to users who have not yet logged in to their systems, select pre-logon from the User/User Group drop-down. • To apply the configuration to any user regardless of login status (both pre-logon and logged in users), select any from the User/User Group drop-down. STEP 8 | (Tunnel Mode only) Configure the ip pools available to assign to the virtual network adapter on the endpoint when an agent establishes a tunnel with the gateway. IP pools and split tunnel settings are not required in internal gateway configurations in non-tunnel mode because agents use the network settings assigned to the physical network adapter. You can optionally use address objects—which allow you to group specific source or destination addresses—when configuring gateway IP address pools or access routes. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 75 2017 Palo Alto Networks, Inc. In a gateway agent configuration, select Agent > IP Pools and configure any of the following settings and then click OK: • To specify the authentication server IP address pool to assign addresses to endpoints that require static IP addresses, select the Retrieve Framed-IP-Address attribute from authentication server check box and then Add the subnet or IP address range to use to assign to remote users in the Authentication Server IP Pool area. When the tunnel is established, an interface is created on the remote user’s computer with an address in the subnet or IP range that matches the Framed-IP attribute of the authentication server. The authentication server IP address pool must be large enough to support all concurrent connections. IP address assignment is static and is retained after the user disconnects. • To specify the IP Pool to use to assign IP addresses, click Add and then specify the IP address range or address object to use. You can configure IPv6 or IPv4 addresses. As a best practice, use a different range of IP addresses from those assigned to endpoints that are physically connected to your LAN to ensure proper routing back to the gateway. STEP 9 | (Tunnel Mode only) Configure the split tunnel settings to assign to the virtual network adapter on the endpoint when an agent establishes a tunnel with the gateway. When configuring the access routes, keep in mind the following: • More specific access routes take precedence over less specific routes. • Avoid specifying the same access route as both an include and exclude access route as this leads to a misconfiguration. To route only some traffic—likely traffic destined for your LAN—to GlobalProtect, specify the destination subnets or address object (of type IP Netmask) that must be included or excluded from the tunnel. In this case, traffic that is not destined for a specified access route will be routed through the endpoint’s physical adapter rather than through the virtual adapter (the tunnel). In a gateway agent configuration, select Agent > Split Tunnel and configure any of the following settings and then click OK: • To disable split tunneling including direct access to local networks on Windows and Mac OS systems, enable No direct access to local network. In this case, users cannot send traffic to proxies or local resources while connected to GlobalProtect. • To define what destination subnets to route through the tunnel click Add in the Access Route area and then enter the routes as follows: • (Optional) In the Includes area, Add the destination subnets or address object (of type IP Netmask) to route only some traffic—likely traffic destined for your LAN—to GlobalProtect. These are the routes the gateway pushes to the remote users’ endpoint and thereby determines what traffic the users’ endpoint can send through the VPN connection. You can include IPv6 or IPv4 subnets. The number of access routes the firewall supports varies by PAN-OS release version: • PAN-OS 8.0.0 and PAN-OS 8.0.1—Up to 100 include access routes, and, with GlobalProtect agent 4.0.2 or a later release, up to 200 include access routes • PAN-OS 8.0.2—Up to 100 include access routes and, with GlobalProtect agent 4.0.2 or a later release, up to 1000 include access routes • (Optional) In the Excludes area, Add the destination subnets or address object (of type IP Netmask) that you want the client to exclude. These routes will be sent through the endpoint’s physical adapter rather than through the virtual adapter (the tunnel). Excluded routes should 76 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 2017 Palo Alto Networks, Inc. be more specific than the included routes; otherwise, you may exclude more traffic than you intended. You can exclude IPv6 or IPv4 subnets. The firewall supports up to 100 exclude access routes, or with GlobalProtect agent 4.0.0 or a later release, up to 200 exclude access routes. Excluding routes is not supported on Android. Only IPv4 routes are supported on Chrome. STEP 10 | Arrange the gateway agent configurations so that the proper configuration is deployed to each agent. When an agent connects, the gateway will compare the source information in the packet against the agent configurations you have defined. As with security rule evaluation, the gateway looks for a match starting from the top of the list. When it finds a match, it delivers the corresponding configuration to the agent or app. • To move a gateway configuration up on the list of configurations, select the configuration and click Move Up. • To move a gateway configuration down on the list of configurations, select the configuration and click Move Down. STEP 11 | (Tunnel Mode only) Specify the network configuration settings for the endpoints. Network settings are not required in internal gateway configurations in non-tunnel mode because in this case agents use the network settings assigned to the physical network adapter. In a GlobalProtect Gateway Configuration, select the Agent > Network Services tab and configure the settings for endpoints in one of the following ways: • If the firewall has an interface that is configured as a DHCP client, set the Inheritance Source to that interface and the GlobalProtect agent will be assigned the same settings received by the DHCP client. You can also Inherit DNS Suffixes from the inheritance source. • Manually assign the DNS server(s) and suffix, and WINS servers by completing the corresponding fields. STEP 12 | (Optional) Define the notification messages end users will see when a security rule with a host information profile (HIP) is enforced. This step only applies if you have created host information profiles and added them to your security policies. For details on configuring the HIP feature and for more detailed information about creating HIP notification messages, see Host Information. In a GlobalProtect Gateway Configuration, select the Agent > HIP Notification tab and Add a new HIP Notification configuration: 1. From the Host Information drop-down, select the HIP object or profile to which this message applies. 2. Select Match Message or Not Match Message and then Enable notifications, depending on whether you want to display the message when the corresponding HIP profile is matched in policy or when it is not matched. In some cases, you might want to create messages for both a match and a non-match, depending on the objects on which you are matching and what your objectives are for the policy. For the Match Message, you can also enable the option to Include Mobile App List to indicate what applications can trigger the HIP match. 3. Select whether you want to display the message as a System Tray Balloon or as a Pop Up Message. 4. Enter and format the text of your message in the Template text box and then click OK. 5. Repeat these steps for each message you want to define. STEP 13 | Save the gateway configuration. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Gateways © 77 2017 Palo Alto Networks, Inc. 1.

GlobalProtect Portal Overview The GlobalProtect Portal provides the management functions for your GlobalProtect infrastructure. Every endpoint that participates in the GlobalProtect network receives configuration information from the portal, including information about available gateways as well as any client certificates that may be required to connect to the gateways. In addition, the portal controls the behavior and distribution of the GlobalProtect agent software to both Mac and Windows laptops. The portal does not distribute the GlobalProtect app for use on mobile devices. To get the GlobalProtect app for mobile devices, end users must download it from the store for their device: App Store for iOS, Google Play for Android, Chrome Web Store for Chromebooks, or Microsoft Store for Windows 10 UWP. However, the agent configurations that get deployed to mobile app users does control the gateway(s) to which the mobile devices have access. For more details on supported versions, see What Client OS Versions are Supported with GlobalProtect? In addition to distributing GlobalProtect client software, you can configure the GlobalProtect portal to provide secure remote access to common enterprise web applications that use HTML, HTML5, and Javascript technologies. Users have the advantage of secure access from SSL-enabled web browsers without installing GlobalProtect client software. This is useful when you need to enable partner or contractor access to applications, and to safely enable unmanaged assets, including personal devices. Refer to GlobalProtect Clientless VPN. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 81 2017 Palo Alto Networks, Inc. Prerequisite Tasks for Configuring the GlobalProtect Portal Before you can configure the GlobalProtect portal, you must complete the following tasks: Create the interfaces (and zones) for the firewall interface where you plan to configure the portal. See Create Interfaces and Zones for GlobalProtect. Set up the portal server certificate, gateway server certificate, SSL/TLS service profiles, and, optionally, any client certificates to deploy to end users to enable SSL/TLS connections for the GlobalProtect™ services. See Enable SSL Between GlobalProtect Components. Define the optional authentication profiles and certificate profiles that the portal can use to authenticate GlobalProtect users. See Authentication. Configure a GlobalProtect Gateway and understand Gateway Priority in a Multiple Gateway Configuration. 82 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 2017 Palo Alto Networks, Inc. Set Up Access to the GlobalProtect Portal After you have completed the Prerequisite Tasks for Configuring the GlobalProtect Portal, configure the GlobalProtect portal as follows: STEP 1 | Add the portal. 1. Select Network > GlobalProtect > Portals and click Add. 2. On the General page, enter a Name for the portal. The name cannot contain spaces. 3. (Optional) Select the virtual system to which this portal belongs from the Location field. STEP 2 | Specify network settings to enable agents to communicate with the portal. If you have not yet created the network interface for the portal, see Create Interfaces and Zones for GlobalProtect for instructions. If you have not yet created an SSL/TLS service profile for the portal, see Deploy Server Certificates to the GlobalProtect Components. Do not attach an interface management profile that allows HTTP, HTTPS, Telnet, or SSH on the interface where you have configured a GlobalProtect portal or gateway because this enables access to your management interface from the Internet. Follow the Best Practices for Securing Administrative Access to ensure that you are securing administrative access to your firewalls in a way that will prevent successful attacks. 1. Select the Interface. 2. Specify the IP Address Type and IP address for the portal web service: • The IP address type can be IPv4 (for IPv4 traffic only), IPv6 (for IPv6 traffic only, or IPv4 and IPv6. Use IPv4 and IPv6 if your network supports dual stack configurations, where IPv4 and IPv6 run at the same time. • The IP address must be compatible with the IP address type. For example, 172.16.1/0 for IPv4 addresses or 21DA:D3:0:2F3B for IPv6 addresses. For dual stack configurations, enter both an IPv4 and IPv6 address. 3. Select an SSL/TLS Service Profile. STEP 3 | Disable the login page entirely or choose your own login page or help page. Although optional, a custom login or help page lets you decide on the look and content of the pages. See Customize the GlobalProtect Portal Login, Welcome, and Help Pages. • Choose a Portal Login Page for user access to the portal or import a new one, or Disable access to the GlobalProtect portal login page from a web browser. • Choose a App Help Page to assist the user with GlobalProtect or import a new one. STEP 4 | Specify how the portal authenticates the users. If you have not yet created a server certificate for the portal and issued gateway certificates, see Deploy Server Certificates to the GlobalProtect Components. On the GlobalProtect Portal Configuration dialog, select Authentication, and then configure any of the following: • To secure communication between the portal and the agents, select the SSL/TLS Service Profile you configured for the portal. • To authenticate users using a local user database or an external authentication service, such as LDAP, Kerberos, TACACS+, SAML, or RADIUS (including OTP), Define the GlobalProtect Client Authentication Configurations. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 83 2017 Palo Alto Networks, Inc. STEP 5 | Save the portal configuration. 1. Click OK to save the settings and close the GlobalProtect Portal Configuration dialog. 2. Commit the changes. 84 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 2017 Palo Alto Networks, Inc. Define the GlobalProtect Client Authentication Configurations Each GlobalProtect client authentication configuration specifies the settings that enable the user to authenticate with the GlobalProtect portal. You can customize the settings for each OS or you can configure the settings to apply to all devices. For example, you can configure Android users to use RADIUS authentication and Windows users to use LDAP authentication. You can also customize the client authentication for users who access the portal from a web browser (to download the GlobalProtect agent) or for third-party IPSec VPN (X-Auth) access to GlobalProtect gateways. STEP 1 | Set Up Access to the GlobalProtect Portal on page 83. 1. Select Network > GlobalProtect > Portals. 2. Select the portal configuration to which you are adding the client configuration and then select the Authentication tab. STEP 2 | Specify how the portal authenticates the users. You can configure the GlobalProtect portal to authenticate users using a local user database or an external authentication service, such as LDAP, Kerberos, TACACS+, SAML, or RADIUS (including OTP). If you have not yet set up the authentication profiles and/or certificate profiles, see Authentication on page 25 for instructions. In the Client Authentication area, Add a new configuration with the following settings: • Enter a Name to identify the client authentication configuration. • Specify the endpoints to which to deploy this configuration. By default, the configuration applies to all endpoints. Otherwise, you can apply the configuration to endpoints running a specific OS (Android, Chrome, iOS, Mac, Windows, or WindowsUWP) or to endpoints that access the portal from a web Browser with the intent of downloading the GlobalProtect agent or to create a new client authentication specifically for GlobalProtect Clientless VPN on page 135. • Select or add an Authentication Profile for authenticating an endpoint that tries to access the gateway. • Enter an Authentication Message to help end users understand which credentials to use when logging in. The message can be up to 100 characters in length (default is Enter login credentials). STEP 3 | Arrange the client authentication configurations with OS-specific configurations at the top of the list, and configurations that apply to Any OS at the bottom of the list. As with security rule evaluation, the portal looks for a match starting from the top of the list. When it finds a match, it delivers the corresponding configuration to the agent or app. • To move a client authentication configuration up on the list of configurations, select the configuration and click Move Up. • To move a client authentication configuration down on the list of configurations, select the configuration and click Move Down. STEP 4 | (Optional) To enable two-factor authentication using an authentication profile and a certificate profile, configure both in this portal configuration. Keep in mind the portal must authenticate the client by using both methods before the user can gain access. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 85 2017 Palo Alto Networks, Inc. Select the corresponding Certificate Profile to authenticate users based on a client certificate or smart card. The Common Name (CN) and, if applicable, the Subject Alternative Name (SAN) fields of the certificate must exactly match the IP address or FQDN of the interface where you configure the portal or HTTPS connections to the portal will fail. STEP 5 | Save the portal configuration. 1. Click OK to save the settings and close the GlobalProtect Portal Configuration dialog. 2. Commit the changes. Define the GlobalProtect Agent Configurations After a GlobalProtect user connects to the portal and is authenticated by the GlobalProtect portal, the portal sends the agent configuration to the agent or app, based on the settings you defined. If you have different roles for users or groups that need specific configurations, you can create a separate agent configuration for each user type or user group. The portal uses the OS of the endpoint and the username or group name to determine the agent configuration to deploy. As with other security rule evaluations, the portal starts to search for a match at the top of the list. When it finds a match, the portal sends the right configuration to the agent or app. The configuration can include the following: • A list of gateways to which the client can connect. • Among the external gateways, any gateway that the user can manually select for the session. • The root CA certificate required to enable the agent or app to establish an SSL connection with the GlobalProtect gateway(s). • The root CA certificate for SSL forward proxy decryption. • The client certificate that the endpoint should present to the gateway when it connects. This configuration is required only if mutual authentication between the client and the portal or gateway is required. • A secure encrypted cookie that the endpoint should present to the portal or gateway when it connects. The cookie is included only if you enable the portal to generate one. • The settings the endpoint uses to determine whether it is connected to the local network or to an external network. • Settings for the behavior of the agent or app, such as what the end users can see in their display, whether they can save their GlobalProtect password, and whether they are prompted to upgrade their software. If the portal is down or unreachable, the agent will use the cached version of its agent configuration from its last successful portal connection to obtain settings, including the gateway(s) to which the agent can connect, what root CA certificate(s) to use to establish secure communication with the gateway(s), and what connect method to use. Use the following procedure to create an agent configuration. STEP 1 | Add one or more trusted root CA certificates to the portal agent configuration to enable the GlobalProtect client to verify the identity of the portal and gateways. The portal deploys the certificate in a certificate file which is read only by GlobalProtect. 1. Select Network > GlobalProtect > Portals. 86 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 2017 Palo Alto Networks, Inc. 2. Select the portal configuration to which you are adding the agent configuration and then select the Agent tab. 3. In the Trusted Root CA field, Add and then select the CA certificate that was used to issue the gateway and/or portal server certificates. The web interface presents a list of CA certificates that are imported on the firewall serving as the GlobalProtect portal. The web interface also excludes end-entity certificates, sometimes referred to as leaf certificates, from the list of certificates you can select. You can also Import a new CA certificate. Use the following best practices when creating and adding certificates: • • Use the same certificate issuer to issue certificates for all of your gateways. Add the entire certificate chain (trusted root CA and intermediate CA certificates) to the portal agent configuration. 4. (Optional) Deploy additional CA certificates for purposes other than GlobalProtect (for example, SSL forward proxy decryption). This option enables you to use the portal to deploy certificates to the endpoint and the agent to install them in the local root certificate store. This can be useful if you do not have another method for distributing these server certificates or prefer to use the portal for certificate distribution. For SSL forward proxy decryption, you specify the forward trust certificate the firewall uses (on Windows and Mac endpoints only) to terminate the HTTPS connection, inspect the traffic for policy compliance, and re-establish the HTTPS connection to forward the encrypted traffic. 1. Add the certificate as described in the previous step. 2. To the right of the certificate, select Install in Local Root Certificate Store. The portal automatically sends the certificate when the user logs in to the portal and installs it in the client's local store thus eliminating the need for you to install the certificate manually. STEP 2 | Add an agent configuration. The agent configuration specifies the GlobalProtect configuration settings to deploy to the connecting agents/apps. You must define at least one agent configuration. 1. In the Agent area, Add a new configuration. 2. Enter a Name to identify the configuration. If you plan to create multiple configurations, make sure the name you define for each is descriptive enough to allow you to distinguish them. STEP 3 | (Optional) Configure settings to specify how users with this configuration will authenticate with the portal. If the gateway is to authenticate the clients by using a client certificate, you must select the source that distributes the certificate. On the Authentication tab, configure any of the following authentication settings: • To enable users to authenticate with the portal using client certificates, select the Client Certificate source (SCEP, Local, or None) that distributes the certificate and its private key to an endpoint. If you use an internal CA to distribute certificates to clients, select None (default). To enable the portal to generate and send a machine certificate to the agent for storage in the local certificate store and use the certificate for portal and gateway authentication, select SCEP and the associated SCEP profile. These certificates are device-specific and can only be used on the endpoint to which it was issued. To use the same certificate for all endpoints, select a certificate that is Local to the portal. With None, the portal does not push a certificate to the client, but you can use can other ways to get a certificate to the client’s endpoint. • Specify whether to Save User Credentials. Select Yes to save the username and password (default), Save Username Only to save only the username, or No to never save credentials. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 87 2017 Palo Alto Networks, Inc. If you configure the portal or gateways to prompt for a dynamic password such as a one-time password (OTP), the user must enter a new password at each login. In this case, the GlobalProtect agent/app ignores the selection to save both the username and password, if specified, and saves only the username. For more information, see Enable Two-Factor Authentication Using One-Time Passwords (OTPs). STEP 4 | If the GlobalProtect endpoint does not require tunnel connections when it is on the internal network, configure internal host detection. 1. On the Internal tab, select the Internal Host Detection check box. 2. Enter the IP Address of a host that can be reached from the internal network only. You can configure IPv4 or IPv6 addressing for Internal Host Detection. The IP address you specify must be compatible with the IP address type. For example, 172.16.1.0 for IPv4 or 21DA:D3:0:2F3b for IPv6. 3. Enter the DNS Hostname for the IP address you entered. Clients that try to connect to GlobalProtect attempt to do a reverse DNS lookup on the specified address. If the lookup fails, the client determines that it is on the external network and then initiates a tunnel connection to a gateway on its list of external gateways. STEP 5 | Set up access to a third-party mobile endpoint management system. This step is required if the mobile devices using this configuration will be managed by a third-party mobile endpoint management system. All devices will initially connect to the portal and, if a third-party mobile endpoint management system is configured on the corresponding portal agent configuration, the device will be redirected to it for enrollment. 1. Enter the IP address or FQDN of the device check-in interface associated with your mobile endpoint management system. The value you enter here must exactly match the value of the server certificate associated with the device check-in interface. You can specify an IPv6 or IPv4 address. 2. Specify the Enrollment Port on which the mobile endpoint management system will be listening for enrollment requests. This value must match the value set on the mobile endpoint management system (default=443). STEP 6 | Configure the user or user group and the endpoint OS to which the agent configuration applies. The portal uses the user/user group settings you specify to determine which configuration to deliver to the GlobalProtect agents that connect. Therefore, if you have multiple configurations, you must make sure to order them properly. As soon as the portal finds a match, it will deliver the configuration. Therefore, more specific configurations must precede more general ones. See 12 for instructions on ordering the list of agent configurations. Select the User/User Group tab and then specify any users, user groups, and/or operating systems to which this configuration should apply: • To deliver this configuration to agents or apps running on specific operating system, Add the OS (Android, Chrome, iOS, Mac, Windows, or WindowsUWP) to which this configuration applies. Or leave the value in this section set to Any to deploy the configuration based on user/group only. • To restrict this configuration to a specific user and/or group, click Add in the User/User Group section of the window and then select the user or group you want to receive this configuration from the drop-down. Repeat this step for each user/group you want to add. Before you can restrict the configuration to specific groups, you must map users to groups as described in Enable Group Mapping. • To restrict the configuration to users who have not yet logged in to their systems, select pre-logon from the User/User Group drop-down. 88 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 2017 Palo Alto Networks, Inc. • To apply the configuration to any user regardless of login status (both pre-logon and logged in users), select any from the User/User Group drop-down. STEP 7 | Specify the external gateways to which users with this configuration can connect. Consider the following best practices when you configure the gateways: • • If you are adding both internal and external gateways to the same configuration, make sure to enable Internal Host Detection. See 4 in Define the GlobalProtect Agent Configurations for instructions. To learn more about how a GlobalProtect client determines the gateway to which it should connect, see Gateway Priority in a Multiple Gateway Configuration. 1. Click Add on the External tab. 2. Enter a descriptive Name for the gateway. The name you enter here should match the name you defined when you configured the gateway and should be descriptive enough for users to know the location of the gateway they are connected to. 3. Enter the FQDN or IP address of the interface where the gateway is configured in the Address field. You can configure an IPv4 or IPv6 address. The address you specify must exactly match the Common Name (CN) in the gateway server certificate. 4. Add one or more Source Regions for the gateway, or select Any to make the gateway available to all regions. When users connect, GlobalProtect recognizes the device region and only allows uses to connect to gateways that are configured for that region. For gateway choices, source region is considered first, then gateway priority. 5. Set the Priority of the gateway by clicking in the field and selecting a value: • If you have only one external gateway, you can leave the value set to Highest (the default). • If you have multiple external gateways, you can modify the priority values (ranging from Highest to Lowest) to indicate a preference for the specific user group to which this configuration applies. For example, if you prefer that the user group connects to a local gateway you would set the priority higher than that of more geographically distant gateways. The priority value is then used to weight the agent’s gateway selection algorithm. • If you do not want agents to automatically establish tunnel connections with the gateway, select Manual only. This setting is useful in testing environments. 6. Select the Manual check box if you want to allow users to be able to manually switch to the gateway. STEP 8 | Specify the internal gateways to which users with this configuration can connect. Make sure you do not use on-demand as the connect method if your configuration includes internal gateways. 1. On the Internal tab, click Add in the Internal Gateways section. 2. Enter a descriptive Name for the gateway. The name you enter here should match the name you defined when you configured the gateway and should be descriptive enough for users to know the location of the gateway they are connected to. 3. Enter the FQDN or IP address of the interface where the gateway is configured in the Address field. You can configure an IPv4 or IPv6 address. The address you specify must exactly match the Common Name (CN) in the gateway server certificate. 4. (Optional) Add one or more Source Addresses to the gateway configuration. The source address can be an IP subnet or range. It can also be a predefined address. GlobalProtect supports both IPv6 and IPv4 addresses. When users connect, GlobalProtect recognizes the source address of the device and only allows users to connect to gateways that are configured for that address. 5. Click OK to save your changes. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 89 2017 Palo Alto Networks, Inc. 6. (Optional) Add a DHCP Option 43 Code to the gateway configuration. You can include one or more sub-option codes associated with the vendor-specific information (Option 43) that the DHCP server has been configured to offer the client. For example, you might have a sub-option code 100 that is associated with an IP address of 192.168.3.1. When a user connects, the GlobalProtect portal sends the list of option codes in the portal configuration to the GlobalProtect agent and the agent selects gateways indicated by the options. When both the source address and DHCP options are configured, the list of available gateways presented to the client is based on the combination (union) of the two configurations. DHCP options are supported on Windows and Mac endpoints only. DHCP options cannot be used to select gateways that use IPv6 addressing. 7. (Optional) Select Internal Host Detection to allow the GlobalProtect agent to determine if it is inside the enterprise network. When the user attempts to log in, the agent does a reverse DNS lookup of the internal Hostname to the specified IP Address. The host serves as a reference point that is reachable if the endpoint is inside the enterprise network. If the agent finds the host, the endpoint is inside the network and the agent connects to an internal gateway; if the agent fails to find the internal host, the endpoint is outside the network and the agent establishes a tunnel to one of the external gateways. You can configure IPv4 or IPv6 addressing for Internal Host Detection. The IP address you specify must be compatible with the IP address type. For example, 172.16.1.0 for IPv4 or 21DA:D3:0:2F3b for IPv6. STEP 9 | Customize the behavior of the GlobalProtect agent for users with this configuration. Select the App tab and then modify the agent settings as desired. For more details about each option, see Customize the GlobalProtect Agent. STEP 10 | (Optional) Define any custom host information profile (HIP) data that you want the agent to collect and/or exclude HIP categories from collection. This step only applies if you plan to use the HIP feature and there is information you want to collect that cannot be collected using the standard HIP objects or if there is HIP information that you are not interested in collecting. See Host Information for details on setting up and using the HIP feature. 1. Select Data Collection and enable the GlobalProtect agent to Collect HIP Data. 2. Select Exclude Categories to exclude specific categories and/or vendors, applications, or versions within a category. For more details, see 3 in Configure HIP-Based Policy Enforcement. 3. Select Custom Checks to define any custom data you want to collect from hosts running this agent configuration, and add the category and vendor. For more details, see 2 in Host Information. STEP 11 | Save the agent configuration. 1. Click OK to save the settings and close the Configs dialog. 2. If you want to add another agent configuration, repeat 2 through 11. STEP 12 | Arrange the agent configurations so that the proper configuration is deployed to each agent. When an agent connects, the portal will compare the source information in the packet against the agent configurations you have defined. As with security rule evaluation, the portal looks for a match starting from the top of the list. When it finds a match, it delivers the corresponding configuration to the agent or app. • To move an agent configuration up on the list of configurations, select the configuration and click Move Up. 90 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 2017 Palo Alto Networks, Inc. • To move an agent configuration down on the list of configurations, select the configuration and click Move Down. STEP 13 | Save the portal configuration. 1. Click OK to save the settings and close the GlobalProtect Portal Configuration dialog. 2. Commit the changes. Customize the GlobalProtect Agent The portal agent configuration allows you to customize how your end users interact with the GlobalProtect agents installed on their systems or the GlobalProtect app installed on their mobile devices. You can define different agent settings for the different GlobalProtect agent configurations you create. For more information on GlobalProtect client requirements, see What Client OS Versions are Supported with GlobalProtect? You can customize the display and behavior of the agent. For example, you can specify the following: • What menus and views users can access. • Whether users can disable the agent (applies to the user-logon connect method only). • Whether to display a welcome page upon successful login. You can also configure whether or not the user can dismiss the welcome page and you can create custom welcome and help pages that explain how to use GlobalProtect within your environment. See Customize the GlobalProtect Portal Login, Welcome, and Help Pages. • Whether agent upgrades occur automatically or whether users are prompted to upgrade. • Prompt users if multi-factor authentication is needed to access sensitive network resources. You can also define agent settings directly from the Windows registry or the global Mac plist. For Windows clients you can also define agent settings directly from the Windows installer (Msiexec). Settings defined in the portal agent configurations in the web interface take precedence over settings defined in the Windows registry/Msiexec or the Mac plist. For more details, see Deploy Agent Settings Transparently. Additional options that are available through the Windows command line (Msiexec) or Windows registry only, enable you to (for more information, see Customizable Agent Settings): • • • • Specify whether the agent should prompt the end user for credentials if Windows SSO fails. Specify the default portal IP address (or hostname). Enable GlobalProtect to initiate a VPN connection before the user logs into the endpoint. Deploy scripts that run before or after GlobalProtect establishes a VPN connection or after GlobalProtect disconnects the VPN connection. • Enable the GlobalProtect agent to wrap third-party credentials on the Windows client, allowing for SSO when using a third-party credential provider. Use the following procedure to customize the GlobalProtect agent. STEP 1 | Select the Agent tab in the agent configuration you want to customize. You can also configure most settings that are on the App tab from a group policy by adding settings to the Windows registry/Mac plist. On Windows systems, you can also set them using the Msiexec utility on the command line during the agent installation. However, settings defined in the web interface or the CLI take precedence over registry/ plist settings. See Deploy Agent Settings Transparently for details. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 91 2017 Palo Alto Networks, Inc. 1. Select Network > GlobalProtect > Portals and select the portal configuration for which you want to add an agent configuration (or Add a new configuration). 2. Select the Agent tab and select the configuration you want to modify (or Add a new configuration). 3. Select the App tab. The App Configurations area displays the options with default values that you can customize for each agent configuration. When you change the default behavior, the web interface changes the color from gray to the default text color. STEP 2 | Specify the Connect Method that an agent or app uses for its GlobalProtect connection. Use the Pre-logon (Always On), Pre-logon then On-demand, or User-log on (Always On) connect method to access the network using an internal gateway. In the App Configurations area, configure any of the following options: • Select a Connect Method: • User-logon (Always On)—The GlobalProtect agent automatically connects to the portal as soon as the user logs in to the endpoint (or domain). When used in conjunction with SSO (Windows users only), GlobalProtect login is transparent to the end user. On iOS endpoints, this setting prevents one-time password (OTP) applications from working because GlobalProtect forces all traffic to go through the tunnel. • Pre-logon (Always On)—Authenticates the user and establishes a VPN tunnel to the GlobalProtect gateway before the user logs in to the client. This option requires that you use an external PKI solution to pre-deploy a machine certificate to each endpoint that receives this configuration. See Remote Access VPN with Pre-Logon for details about pre-logon. • On-demand (Manual user initiated connection)—Users will have to manually launch the agent to connect to GlobalProtect. Use this connect method for external gateways only. • Pre-logon then On-demand—Similar to the Pre-logon (Always On) connect method, this connect method (which requires Content Release version 590-3397 or later) enables the GlobalProtect agent to authenticate the user and establish a VPN tunnel to the GlobalProtect gateway before the user logs in to the client. Unlike the pre-logon connection method, after the user logs in to the client, users must manually launch the agent to connect to GlobalProtect if the connection is terminated for any reason. The benefit of this option is that you can allow a user to specify a new password after password expiration or a user forgets their password but still require the user to manually initiate the connection after the user logs in. STEP 3 | Specify whether to enforce GlobalProtect connections for network access. To enforce GlobalProtect for network access, we recommend that you enable this feature only for users that connect in User-logon or Pre-logon modes. Users that connect in On-demand mode may not be able to establish a connection within the permitted grace periods. In the App Configurations area, configure any of the following options: • To force all network traffic to traverse a GlobalProtect tunnel, set Enforce GlobalProtect Connection for Network Access to Yes. By default, GlobalProtect is not required for network access meaning users can still access the internet if GlobalProtect is disabled or disconnected. To provide instructions to users before traffic is blocked, configure a Traffic Blocking Notification Message and optionally specify when to display the message (Traffic Blocking Notification Delay). 92 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 2017 Palo Alto Networks, Inc. When Enforce GlobalProtect Connection for Network Access is enabled, you may want to consider allowing users to disable the GlobalProtect agent with a passcode. The Enforce GlobalProtect Connection for Network Access feature enhances the network security by requiring a GlobalProtect VPN connection for network access. On rare occasions, devices may fail to connect to the VPN and require remote administrative login for troubleshooting. By disabling the GlobalProtect agent (for Windows or Mac) using the passcode provided by the administrator during the troubleshooting session, you can allow administrators to connect to your device remotely. • To permit traffic required to establish a connection with a captive portal, specify a Captive Portal Exception Timeout. The user must authenticate with the portal before the timeout expires. To provide additional instructions, configure a Captive Portal Detection Message. These features require Content Release version 607-3486 or later. STEP 4 | Specify additional GlobalProtect connection settings. With single sign-on (SSO) enabled (the default), the GlobalProtect agent uses the user’s Windows login credentials to automatically authenticate to and connect to the GlobalProtect portal and gateway. GlobalProtect with SSO enabled also allows for the GlobalProtect agent to wrap third-party credentials to ensure that Windows users can authenticate and connect, even when a third-party credential provider is being used to wrap the Windows login credentials. In the App Configurations area, configure any of the following options: • (Windows only) Set Use Single Sign-On to No to disallow GlobalProtect to use the Windows login credentials to automatically authenticate the user upon login to Active Directory. • Enter the Maximum Internal Gateway Connection Attempts to specify the number of times the GlobalProtect agent should retry the connection to an internal gateway after the first attempt fails (range is 0-100; 4 or 5 is recommended; default is 0, which means the GlobalProtect agent does not retry the connection). By increasing the value, you enable the agent to connect to an internal gateway that is temporarily down or unreachable during the first connection attempt but comes back up before the specified number of retries are exhausted. Increasing the value also ensures that the internal gateway receives the most up-to-date user and host information. • Enter the GlobalProtect App Config Refresh Interval (hours) to specify the number of hours the GlobalProtect portal waits before it initiates the next refresh of a client’s configuration (range is 1-168; default is 24). • Specify whether to Retain Connection on Smart Card Removal. By default, the option is set to Yes, meaning GlobalProtect retains the tunnel when a user removes a smart card containing a client certificate. To terminate the tunnel, set this option to No. The decision on whether to retain the connection depends on your security requirements. This feature requires Content Release version 590-3397 or a later version. • Configure an Automatic Restoration of VPN Connection Timeout to specify the action GlobalProtect takes when the tunnel is disconnected by entering a timeout value in minutes from 0 to 180; default is 30. A value of 0 disables this feature so that GlobalProtect does not attempt to reconnect after the tunnel is disconnected. When you specify a value of 1-180 minutes, GlobalProtect attempts to reestablish the tunnel connection if the tunnel is down for a period of time which does not exceed the timeout value you specify here. For example, with a timeout value of 30 minutes, GlobalProtect does not attempt to reconnect if the tunnel is disconnected for 45 minutes. However, if the tunnel is GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 93 2017 Palo Alto Networks, Inc. disconnected for 15 minutes, GlobalProtect attempts to reconnect because the number of minutes has not exceeded the timeout value. When you enable Automatic Restoration of VPN Connection Timeout, you can also adjust the amount of time in seconds GlobalProtect waits between attempts to restore the connection by configuring the Wait Time Between VPN Connection Restore Attempts. Range is 1 to 60 seconds; the default is 5. With Always-On VPN, if a user switches from an external network to an internal network before the timeout value expires, GlobalProtect does not perform network discovery. As a result, GlobalProtect restores the connection to the last known external gateway. To trigger internal host detection, the user must select Rediscover Network from the GlobalProtect console. STEP 5 | Configure the menus and UI views that are available to users who have this agent configuration. Configure any or all of the following options: • If you want users to be able to see only basic status information within the application, set Enable Advanced View to No. By default, the advanced view is enabled. It allows users to see detailed statistical, host, and troubleshooting information and to perform certain tasks, such as changing their password. • If you want hide the GlobalProtect agent on end-user systems, set Display GlobalProtect Icon to No. When the icon is hidden, users cannot perform other tasks such as changing passwords, rediscovering the network, resubmitting host information, viewing troubleshooting information, or performing an on-demand connection. However, HIP notification messages, login prompts, and certificate dialogs will still display as necessary for interacting with the end user. • To prevent users from performing a network rediscovery, set the Enable Rediscover Network Option to No. When you disable the option, it is grayed out in the GlobalProtect menu. • To prevent users from manually resubmitting HIP data to the gateway, set Enable Resubmit Host Profile Option to No. This option is enabled by default, and is useful in cases where HIPbased security policy prevents users from accessing resources because it allows the user to fix the compliance issue on the computer and then resubmit the HIP. • (Windows only) To allow GlobalProtect to display notifications in the notification area (system tray), set Show System Tray Notifications to Yes. • To create a custom message to display to users when their password is about to expire configure the Custom Password Expiration Message (LDAP Authentication Only). The maximum message length is 200 characters. STEP 6 | Define what the end users with this configuration can do in their client. • Set Allow User to Change Portal Address to No to disable the Portal field on the Home tab in the GlobalProtect agent. Because the user will then be unable to specify a portal to which to connect, you must supply the default portal address in the Windows registry (HKEY_LOCAL_MACHINE \SOFTWARE\Palo Alto Networks\GlobalProtect\PanSetup with key Portal) or the Mac plist (/Library/Preferences/com.paloaltonetworks.GlobalProtect.settings.plist with key Portal under dictionary PanSetup). For more information, see Deploy Agent Settings Transparently. • To prevent users from dismissing the welcome page, set Allow User to Dismiss Welcome Page to No. Otherwise, when set to Yes, the user can dismiss the welcome page and prevent GlobalProtect from displaying the page after subsequent logins. STEP 7 | Specify whether users can disable the GlobalProtect agent. 94 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 2017 Palo Alto Networks, Inc. The Allow User to Disable GlobalProtect option applies to agent configurations that have the Connect Method set to User-Logon (Always On). In user-logon mode, the agent or app automatically connects to GlobalProtect as soon as the user logs in to the endpoint. This mode is sometimes referred to as “always on,” which is why the user must override this behavior to disable GlobalProtect client. By default, this option is set to Allow which permits users to disable GlobalProtect without providing a comment, passcode, or ticket number. If the agent icon is not visible, users are not able to disable the GlobalProtect client. See 5 for details. • To prevent users with the user-logon connect method from disabling GlobalProtect, set Allow User to Disable GlobalProtect to Disallow. • To allow users to disable GlobalProtect if they provide a passcode, set Allow User to Disable GlobalProtect to Allow with Passcode. Then, in the Disable GlobalProtect App area, enter (and confirm) the Passcode that the end users must supply. • To allow users to disconnect if they provide a ticket, set Allow User to Disable GlobalProtect to Allow with Ticket. With this option, the disconnect action triggers the agent to generate a Request Number. The end user must then communicate the Request Number to the administrator. The administrator then clicks Generate Ticket on the Network > GlobalProtect > Portals page and enters the request number from the user to generate the ticket. The administrator then provides the ticket to the end user, who enters it into the Disable GlobalProtect dialog to enable the agent to disconnect. • To limit the number of times users can disable the GlobalProtect client, enter a value in the Max Times User Can Disable field in the Disable GlobalProtect App area. A value of 0 (the default) indicates that users are not limited in the number of times they can disable the client. • To restrict how long the user may be disconnected, enter a value (in minutes) in the User Can Disable Timeout (min) field in the Disable GlobalProtect App area. A value of 0 (the default) means that there is no restriction on how long the user can keep the client disabled. STEP 8 | Configure the certificate settings and behavior for the users that receive this configuration. • Client Certificate Store Lookup—Select which store the agent should use to look up client certificates. User certificates are stored in the Current User certificate store on Windows and in the Personal Keychain on Mac OS. Machine certificates are stored in the Local Computer certificate store on Windows and in the System Keychain on Mac OS. By default, the agent looks for User and machine certificates in both places. • SCEP Certificate Renewal Period (days)—With SCEP, the portal can request a new client certificate before the certificate expires. This time before the certificate expires is the optional SCEP certificate renewal period. During a configurable number of days before a client certificate expires, the portal can request a new certificate from the SCEP server in your enterprise PKI (range is 0-30; default is 7). A value of 0 means the portal does not automatically renew the client certificate when it refreshes the agent configuration. For an agent or app to obtain the new certificate during the renewal period, the user must log in to the GlobalProtect client. For example, if a client certificate has a lifespan of 90 days, the certificate renewal period is 7 days, and the user logs in during the final 7 days of the certificate lifespan, the GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 95 2017 Palo Alto Networks, Inc. portal acquires a new certificate and deploys it along with a fresh agent configuration. For more information, see Deploy User-Specific Client Certificates for Authentication. • Extended Key Usage OID for Client Certificate (Windows and Mac endpoints only)—Use this option only if you enabled client authentication, expect multiple client certificates to be present on the endpoint, and have identified a secondary purpose by which you can filter the client certificates. This option enables you to specify a secondary purpose for a client certificate using the associated object identifier (OID). For example, to display only client certificates which also have a purpose of Server Authentication, enter the OID 1.3.6.1.5.5.7.3.1. When the GlobalProtect agent finds only one client certificate which matches the secondary purpose, GlobalProtect automatically selects and authenticates using that certificate. Otherwise, GlobalProtect prompts the user to select the client certificate from the filtered list of client certificates which match the criteria. For more information including a list of common certificate purposes and OIDs, see the PAN-OS 7.1 New Feature’sGuide. • If you do not want the agent to establish a connection with the portal when the portal certificate is not valid, set Allow User to Continue with Invalid Portal Server Certificate to No. Keep in mind that the portal provides the agent configuration only; it does not provide network access and therefore security to the portal is less critical than security to the gateway. However, if you have deployed a trusted server certificate for the portal, deselecting this option can help prevent man-in-the-middle (MITM) attacks. STEP 9 | Specify whether users receive login prompts when multi-factor authentication is required to access sensitive network resources. For internal gateway connections, sensitive network resources (for example, financial applications or software development applications) may require additional authentication. You can configure GlobalProtect clients to display the authentication prompts required to access these resources. Refer to Configure GlobalProtect to Facilitate Multi-Factor Authentication Notifications for more information. • Set Enable Inbound Authentication Prompts from MFA Gateways to Yes. To support multi-factor authentication (MFA), a GlobalProtect client must receive and acknowledge UDP prompts that are inbound from the gateway. Select Yes to enable a GlobalProtect client to receive and acknowledge the prompt. By default, the value is set to No meaning GlobalProtect will block UDP prompts from the gateway. • In Network Port for Inbound Authentication Prompts (UDP), specify the port number a GlobalProtect client uses to receive inbound authentication prompts from MFA gateways. The default port is 4501. To change the port, specify a number from 1 to 65535. • In Trusted MFA Gateways, specify the list of authentication gateways a GlobalProtect client will trust for multi-factor authentication. When a GlobalProtect client receives a UDP message on the specified network port, GlobalProtect displays an authentication message only if the UDP prompt comes from a trusted gateway. • Configure the Inbound Authentication Message (for example: You have attempted to access a protected resource that requires additional authentication. Proceed to authenticate at). When users try to access a resource that requires additional authentication, GlobalProtect receives an inbound authentication prompt and displays this message. GlobalProtect automatically appends the URL for the Authentication Portal page you specify when you configure multi-factor authentication to the inbound authentication message. STEP 10 | (Windows only) Configure settings for Windows-based endpoints that receive this configuration. • Resolve All FQDNs Using DNS Servers Assigned by the Tunnel (Windows Only)— Configure the DNS resolution preferences for the GlobalProtect tunnel. Select No to allow Windows endpoints to send DNS queries to the DNS server set on the physical adapter if the initial query to the DNS server configured on the gateway is not resolved. This option retains the native Windows behavior to query all DNS servers on all adapters recursively but can result in long wait times to resolve some DNS queries. Select Yes (default) to allow Windows endpoints to resolve all DNS queries with the DNS 96 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 2017 Palo Alto Networks, Inc. servers you configure on the gateway instead of allowing the endpoint to send some DNS queries to the DNS servers set on the physical adapter. This features requires Content Release version 731 or later and is available for GlobalProtect agent 4.0.3 and later. To configure DNS settings for GlobalProtect agent 4.0.2 and earlier releases, use the Update DNS Settings at Connect option. • Update DNS Settings at Connect—Select Yes to enable the Windows endpoint to resolve all DNS queries with the DNS servers you configure for the gateway instead of the DNS servers set for the physical adapter on the endpoint. When you enable this option, GlobalProtect strictly enforces the gateway DNS settings and overrides the static settings for all physical adapters. This is useful when a Windows endpoint fails to resolve a DNS query sent to the DNS server configured on the physical adapter instead of on the GlobalProtect tunnel adapter. Select No (the default) to allow Windows endpoints to send DNS queries to the DNS server set on the physical adapter if the initial query to the DNS server configured on the gateway is not resolved. This option retains the native Windows behavior to query all DNS servers on all adapters recursively but can result in long wait times to resolve some DNS queries. • • • • This feature is deprecated in 4.0.3 and later releases. To configure DNS resolution settings for GlobalProtect agent 4.0.3 and later releases, use the Resolve All FQDNs Using DNS Servers Assigned by the Tunnel (Windows Only) option. Send HIP Report Immediately if Windows Security Center (WSC) State Changes—Select No to prevent the GlobalProtect agent from sending HIP data when the status of the Windows Security Center (WSC) changes. Select Yes (default) to immediately send HIP data when the status of the WSC changes. Detect Proxy for Each Connection—Select No to auto-detect the proxy for the portal connection and use that proxy for subsequent connections. Select Yes (default) to auto-detect the proxy at every connection. Clear Single Sign-On Credentials on Logout—Select No to keep single sign-on credentials when the user logs out. Select Yes (default) to clear them and force the user to enter credentials upon the next login. Use Default Authentication on Kerberos Authentication Failure—Select No to use only Kerberos authentication. Select Yes (default) to retry using the default authentication method after authentication using Kerberos fails. STEP 11 | If your endpoints frequently experience latency or slowness when connecting to the GlobalProtect portal or gateways, consider adjusting the portal and TCP timeout values. To allow more time for your endpoints to connect to or receive data from the portal or gateway, increase the timeout values, as needed. Keep in mind that increasing the values can result in longer wait times if the GlobalProtect agent is unable to establish the connection. In contrast, decreasing the values can prevent the GlobalProtect agent from establishing a connection when the portal or gateway does not respond before the timeout expires. Configure values for any of the following options: • Portal Connection Timeout (sec)—The number of seconds (between 1 and 600) before a connection request to the portal times out due to no response from the portal. When your firewall is running Applications and Threats content versions earlier than 777-4484, the default is 30. Starting with content version 777-4484, the default is 5. • TCP Connection Timeout (sec)—The number of seconds (between 1 and 600) before a TCP connection request times out due to unresponsiveness from either end of the connection. When your firewall is running Applications and Threats content versions earlier than 777-4484, the default is 60. Starting with content version 777-4484, the default is 5. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 97 2017 Palo Alto Networks, Inc. • TCP Receive Timeout (sec)—The number of seconds before a TCP connection times out due to the absence of some partial response of a TCP request (range is 1-600; default is 30). STEP 12 | Specify whether remote desktop connections are permitted over existing VPN tunnels by specifying the User Switch Tunnel Rename Timeout. When a new user connects to a Windows machine using Remote Desktop Protocol (RDP), the gateway reassigns the VPN tunnel to the new user. The gateway can then enforce security policies on the new user. Allowing remote desktop connections over VPN tunnels can be useful in situations where an IT administrator needs to access a remote end-user system using RDP. By default, the User Switch Tunnel Rename Timeout field is set to 0 meaning the GlobalProtect gateway terminates the connection if a new user authenticates over the VPN tunnel. To modify this behavior, configure a timeout value from 1 to 600 seconds. If the new user does not log in to the gateway before the timeout value expires, the GlobalProtect gateway terminates the VPN tunnel assigned to the first user. Changing the User Switch Tunnel Rename Timeout value only affects the RDP tunnel and does not rename a pre-logon tunnel when configured. STEP 13 | Specify how GlobalProtect agent upgrades occur. If you want to control when users can upgrade, you can customize the agent upgrade on a perconfiguration basis. For example, if you want to test a release on a small group of users before deploying it to your entire user base, you can create a configuration that applies to users in your IT group only, thus allowing them to upgrade and test and disable upgrade in all other user/group configurations. Then, after you have thoroughly tested the new version, you can modify the agent configurations for the rest of your users to allow the upgrade. By default, the Allow User to Upgrade GlobalProtect App field is set to prompt the end user to upgrade. To modify this behavior, select one of the following options: • Allow Transparently—Upgrades occur automatically without interaction with the user. Upgrades can occur when the user is working remotely or connected from within the corporate network. • Internal—Upgrades occur automatically without interaction with the user, provided the user is connected from within the corporate network. This setting is recommended to prevent slow upgrades in low-bandwidth situations. When a user connects outside the corporate network, the upgrade is postponed and re-activated later when the user connects from within the corporate network. You must configure internal gateways and internal host detection to use this option. • To prevent agent upgrades, select Disallow. • To allow end users to initiate agent upgrades, select Allow Manually. In this case, the user would select the Check Version option in the agent to determine if there is a new agent version and then upgrade if desired. Note that this option will not work if the GlobalProtect agent is hidden from the user. See 5 for details on the Display GlobalProtect Icon option. Upgrades for Allow Transparently and Internal occur only if the GlobalProtect software version on the portal is more recent than the GlobalProtect software version on the endpoint. For example, a GlobalProtect 3.1.3 agent connecting to a GlobalProtect 3.1.1 portal is not upgraded. STEP 14 | Specify whether to display a welcome page upon successful login. A welcome page can be a useful way to direct users to internal resources that they can only access when connected to GlobalProtect, such as your Intranet or other internal servers. By default, the only indication that the agent has successfully connected to GlobalProtect is a balloon message that displays in the system tray/menubar. 98 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Portals © 2017 Palo Alto Networks, Inc. To display a welcome page after a successful login select factory-default from the Welcome Page drop-down on the right. GlobalProtect displays the welcome page in the default browser on Windows, Mac, and Chromebook endpoints, or within the GlobalProtect app on mobile devices. You can also select a custom welcome page that provides information specific to your users, or to a specific group of users (based on which portal configuration gets deployed). For details on creating custom pages, see Customize the GlobalProtect Portal Login, Welcome, and Help Pages. STEP 15 | Save the agent configuration settings. 1.

Deploy the GlobalProtect Client Software In order to connect to GlobalProtect™, an end host must be running GlobalProtect client software. The software deployment method depends on the type of client as follows: • Mac OS and Microsoft Windows endpoints—Require the GlobalProtect agent software, which is distributed by the GlobalProtect portal. To enable the software for distribution, you must download the version you want the hosts in your network to use to the firewall hosting your GlobalProtect portal and then activate the software for download. For instructions on how to download and activate the agent software on the firewall, see Deploy the GlobalProtect Agent Software. • Windows 10 phone and Windows 10 UWP endpoints—Require the GlobalProtect app. As with other mobile device apps, the end user must download the GlobalProtect app from the Microsoft Store. For instructions on how to download and test the GlobalProtect app installation, see Download and Install the GlobalProtect Mobile App. • iOS and Android endpoints—Require the GlobalProtect app. As with other mobile device apps, the end user must download the GlobalProtect app either from the Apple AppStore (iOS devices) or from Google Play (Android devices). For instructions on how to download and test the GlobalProtect app installation, see Download and Install the GlobalProtect Mobile App. • Chromebooks—Require the GlobalProtect app for Chrome OS. Similar to the download process for mobile device apps, the end user can download the GlobalProtect app from the Chrome Web Store. You can also deploy the app to a managed Chromebook using the Chromebook Management Console. For instructions on how to download and test the GlobalProtect app installation, Download and Install the GlobalProtect App for Chrome OS. For more details, see What Client OS Versions are Supported with GlobalProtect? As an alternative to deploying GlobalProtect client software, you can configure the GlobalProtect portal to provide secure remote access to common enterprise web applications that use HTML, HTML5, and Javascript technologies. Users have the advantage of secure access from SSL-enabled web browsers without installing GlobalProtect client software. Refer to GlobalProtect Clientless VPN. Deploy the GlobalProtect Agent Software There are several ways to deploy the GlobalProtect agent software: • Directly from the portal—Download the agent software to the firewall hosting the portal and activate it so that end users can install the updates when they connect to the portal. This option provides flexibility in that it allows you to control how and when end users receive updates based on the agent configuration settings you define for each user, group, and/or operating system. However, if you have a large number of agents that require updates, it could put extra load on your portal. See Host Agent Updates on the Portal for instructions. • From a web server—If you have a large number of hosts that will need to upgrade the agent simultaneously, consider hosting the agent updates on a web server to reduce the load on the firewall. See Host Agent Updates on a Web Server for instructions. • Transparently from the command line—For Windows clients, you can automatically deploy agent settings in the Windows Installer (Msiexec). However, to upgrade to a later agent version using Msiexec, you must first uninstall the existing agent. In addition, Msiexec allows for deployment of agent settings directly on the endpoints by setting values in the Windows registry or Mac plist. See Deploy Agent Settings Transparently. • Using group policy rules—In Active Directory environments, the GlobalProtect Agent can also be distributed to end users, using active directory group policy. AD Group policies allow modification of Windows host computer settings and software automatically. Refer to the article at http:// GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 103 2017 Palo Alto Networks, Inc. support.microsoft.com/kb/816102 for more information on how to use Group Policy to automatically distribute programs to host computers or users. • From a mobile endpoint management system—If you use an mobile management system such as an MDM or EMM to manage your mobile devices, you can use the system to deploy and configure the GlobalProtect app. See Mobile Endpoint Management. Host Agent Updates on the Portal The simplest way to deploy the GlobalProtect agent software is to download the new agent installation package to the firewall that is hosting your portal and then activate the software for download to the agents connecting to the portal. To do this automatically, the firewall must have a service route that enables it to access the Palo Alto Networks Update Server. If the firewall does not have access to the Internet, you can manually download the agent software package from the Palo Alto Networks Software Updates support site using an Internet-connected computer and then manually upload it to the firewall. You must have a valid Palo Alto Networks account to log in to and download software from the Software Updates page. If you cannot log in and need assistance, go to https:// www.paloaltonetworks.com/support/tabs/overview.html.) You define how the agent software updates are deployed in the agent configurations you define on the portal—whether they happen automatically when the agent connects to the portal, whether the user is prompted to upgrade the agent, or whether the end user can manually check for and download a new agent version. For details on creating an agent configuration, see Define the GlobalProtect Agent Configurations on page 86. STEP 1 | Launch the web interface on the firewall hosting the GlobalProtect portal and go to the GlobalProtect Client page. Select Device > GlobalProtect Client. STEP 2 | Check for new agent software images. • If the firewall has access to the Update Server, click Check Now to check for the latest updates. If the value in the Action column is Download it indicates that an update is available. • If the firewall does not have access to the Update Server, go to the Palo Alto Networks Software Updates support site and Download the file to your computer. Then go back to the firewall to manually Upload the file. You must have a valid Palo Alto Networks account to log in to and download software from the Software Updates page. If you cannot log in and need assistance, go to: https:// www.paloaltonetworks.com/support/tabs/overview.html) STEP 3 | Download the agent software image. If your firewall does not have Internet access from the management port, you can download the agent update from the Palo Alto Networks Support Site: (https:// www.paloaltonetworks.com/support/tabs/overview.html). You can then manually Upload the update to your firewall and then activate Activate From File. Locate the agent version you want and then click Download. When the download completes, the value in the Action column changes to Activate. 104 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 2017 Palo Alto Networks, Inc. If you manually uploaded the agent software as detailed in 2 on page 104, the Action column will not update. Continue to the next step for instructions on activating an image that was manually uploaded. STEP 4 | Activate the agent software image so that end users can download it from the portal. Only one version of agent software image can be activated at a time. If you activate a new version, but have some agents that require a previously activated version, you will have to activate the required version again to enable it for download. • If you downloaded the image automatically from the Update Server, click Activate. • If you manually uploaded the image to the firewall, click Activate From File and then select the GlobalProtect Client File you uploaded from the drop-down. Click OK to activate the selected image. You may need to refresh the screen before the version displays as Currently Activated. Host Agent Updates on a Web Server If you have a large number of endpoints that will need to install and/or update the GlobalProtect agent software, consider hosting the GlobalProtect agent software images on an external web server. This helps reduce the load on the firewall when users connect to download the agent. To use this feature, the firewall hosting the portal must be running PAN-OS 4.1.7 or a later release. STEP 1 | Download the version of the GlobalProtect agent that you plan to host on the web server to the firewall and activate it. Follow the steps for downloading and activating the agent software on the firewall as described in Host Agent Updates on the Portal. STEP 2 | Download the GlobalProtect agent image you want to host on your web server. You should download the same image that you activated on the portal. From a browser, go to the Palo Alto Networks Software Updates site and Download the file to your computer. STEP 3 | Publish the files to your web server. Upload the image file(s) to your web server. STEP 4 | Redirect the end users to the web server. On the firewall hosting the portal, log in to the CLI and enter the following operational mode commands: > set global-protect redirect on > set global-protect redirect location where is the path is the URL to the folder hosting the image, for example https://acme/GP. STEP 5 | Test the redirect. 1. Launch your web browser and go to the following URL: https:// For example, https://gp.acme.com. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 105 2017 Palo Alto Networks, Inc. 2. On the portal login page, enter your user Name and Password and then click Login. After successful login, the portal should redirect you to the download. Test the Agent Installation Use the following procedure to test the agent installation. STEP 1 | Create an agent configuration for testing the agent installation. When initially installing the GlobalProtect agent software on the endpoint, the end user must be logged in to the system using an account that has administrative privileges. Subsequent agent software updates do not require administrative privileges. As a best practice, create an agent configuration that is limited to a small group of users, such as administrators in the IT department responsible for administering the firewall: 1. Select Network > GlobalProtect > Portals and select the portal configuration to edit. 2. Select the Agent tab and either select an existing configuration or Add a new configuration to deploy to the test users/group. 3. On the User/User Group tab, click Add in the User/User Group section, select the user or group who will be testing the agent, and then click OK. 4. On the Agent tab, make sure Agent Upgrade is set to prompt and then click OK to save the configuration. 5. (Optional) Select the agent configuration you just created/modified and click Move Up so that it is before any more generic configurations you have created. 6. Commit the changes. STEP 2 | Log in to the GlobalProtect portal. 1. Launch your web browser and go to the following URL: https:// For example, https://gp.acme.com. 2. On the portal login page, enter your user Name and Password and then click Login. STEP 3 | Navigate to the agent download page. In most cases, you will see an agent download page when you log in to the portal. Use this page to download the latest agent software package. 106 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 2017 Palo Alto Networks, Inc. If you have enabled GlobalProtect Clientless VPN access, you will see an applications page (instead of the agent download page) when you log in to the portal. Select GlobalProtect Agent to open the download page. STEP 4 | Download the agent. 1. Click the link that corresponds to the operating system you are running on your computer to begin the download. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 107 2017 Palo Alto Networks, Inc. 2. When prompted to run or save the software, click Run. 3. When prompted, click Run to launch the GlobalProtect Setup Wizard. When initially installing the GlobalProtect agent software on the endpoint, the end user must be logged in to the system using an account that has administrative privileges. Subsequent agent software updates do not require administrative privileges. STEP 5 | Complete the GlobalProtect agent setup. 1. From the GlobalProtect Setup Wizard, click Next. 2. Click Next to accept the default installation folder (C:\Program Files\Palo Alto Networks\GlobalProtect) or Browse to choose a new location and then click Next twice. 3. After the installation successfully completes, click Close. The GlobalProtect agent will automatically start. STEP 6 | Log in to GlobalProtect. Enter the FQDN or IP address of the Portal and Connect. If prompted, enter your Username and Password and Connect. If authentication is successful, the agent will connect to GlobalProtect. Use the agent to access resources on the corporate network as well as external resources, as defined in the corresponding security polices. 108 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 2017 Palo Alto Networks, Inc. To deploy the agent to end users, create agent configurations for the user groups for which you want to enable access and set the Agent Upgrade settings appropriately and then communicate the portal address. See Define the GlobalProtect Agent Configurations for details on setting up agent configurations. Download and Install the GlobalProtect Mobile App The GlobalProtect app provides a simple way to extend the enterprise security policies out to mobile devices. As with other remote hosts running the GlobalProtect agent, the mobile app provides secure access to your corporate network over an IPSec or SSL VPN tunnel. The app will automatically connect to the gateway that is closest to the end user’s current location. In addition, traffic to and from the mobile device is automatically subject to the same security policy enforcement as other hosts on your corporate network. Like the GlobalProtect agent, the app collects information about the host configuration and can use this information for enhanced HIP-based security policy enforcement. There are two primary methods for installing the GlobalProtect app: You can deploy the app from your third-party MDM and transparently push the app to your managed devices; or, you can install the app directly from the official store for your device: • • • • iOS endpoints—App Store Android endpoints—Google Play Windows 10 phones and Windows 10 UWP endpoints—Microsoft Store Chromebooks—For details on installing the GlobalProtect app for Chrome OS, see Download and Install the GlobalProtect App for Chrome OS.

Deploy Agent Settings Transparently As an alternative to deploying agent settings from the portal configuration, you can define them directly from the Windows registry or global Mac plist or—on Windows clients only—using the Windows Installer (Msiexec). The benefit is that it enables deployment of GlobalProtect agent settings to endpoints prior to their first connection to the GlobalProtect portal. Settings defined in the portal configuration always override settings defined in the Windows registry or Mac plist. So if you define settings in the registry or plist, but the portal configuration specifies different settings, the settings the agent receives from the portal will override the settings defined on the client. This override also applies to login-related settings, such as whether to connect on-demand, whether to use single sign-on (SSO), and whether the agent can connect if the portal certificate is invalid. Therefore, you should avoid conflicting settings. In addition, the portal configuration is cached on the endpoint and that cached configuration is be used anytime the GlobalProtect agent is restarted or the client machine is rebooted. The following sections describe the customizable agent settings available and how to deploy these settings transparently to Windows and Mac clients: • Customizable Agent Settings on page 115 • Deploy Agent Settings to Windows Clients on page 122 • Deploy Agent Settings to Mac Clients on page 131 In addition to using Windows registry and Mac plist to deploy GlobalProtect agent settings, you can enable the GlobalProtect agent to collect specific Windows registry or Mac plist information from clients, including data on applications installed on the clients, processes running on the clients, and attributes or properties of those applications and processes. You can then monitor the data and add it to a security rule as matching criteria. Device traffic that matches registry settings you have defined can be enforced according to the security rule. Additionally, you can set up custom checks to Collect Application and Process Data From Clients on page 184. Customizable Agent Settings In addition to pre-deploying the portal address, you can also define the agent configuration settings. To Deploy Agent Settings to Windows Clients you define keys in the Windows registry (HKEY_LOCAL_MACHINE\SOFTWARE\Palo Alto Networks\GlobalProtect), or, to Deploy Agent Settings to Mac Clients you define entries in the PanSetup dictionary of the Mac plist (/Library/ Preferences/com.paloaltonetworks.GlobalProtect.settings.plist). On Windows clients only, you can also use the Windows Installer to Deploy Agent Settings from Msiexec. The following topics describe each customizable agent setting. Settings defined in the GlobalProtect portal agent configuration take precedence over settings defined in the Windows registry or the Mac plist. Some settings do not have a corresponding portal configuration settings on the web interface, and must be configured using Windows registry or Msiexec. These additional settings include: can-prompt-user-credential, wrap-cp-guid, and filter-nongpcp. • • • • Agent Display Options User Behavior Options Agent Behavior Options Script Deployment Options GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 115 2017 Palo Alto Networks, Inc.

Deploy Agent Settings in the Windows Registry You can enable deployment of GlobalProtect agent settings to Windows clients prior to their first connection to the GlobalProtect portal by using the Windows registry. Use the options described in the following table to begin using the Windows registry to customize agent settings for Windows clients. In addition to using Windows registry to deploy GlobalProtect agent settings, you can enable the GlobalProtect agent to collect specific Windows registry information from Windows clients. You can then monitor the data and add it to a security rule as matching criteria. Device traffic that matches registry settings you have defined can be enforced according to the security rule. Additionally, you can set up custom checks to Collect Application and Process Data From Clients. • Locate the GlobalProtect agent customization settings in the Windows registry. Open the Windows registry (enter regedit at the command prompt) and go to: HKEY_LOCAL_MACHINE\SOFTWARE\Palo Alto Networks\GlobalProtect\Settings\ • Set the portal name. If you do not want the user to manually enter the portal address even for the first connection, you can pre-deploy the portal address through the Windows registry: (HKEY_LOCAL_MACHINE\SOFTWARE \Palo Alto Networks\GlobalProtect\PanSetup with key Portal). • Deploy various settings to the Windows client from the Windows registry, including configuring the connect method for the GlobalProtect agent and enabling single sign-on (SSO).

Enable SSO Wrapping for Third-Party Credentials with the Windows Registry. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 123 2017 Palo Alto Networks, Inc. Deploy Agent Settings from Msiexec On Windows endpoints, you have the option to deploy the agent and the settings automatically from the Windows Installer (Msiexec) by using the following syntax: msiexec.exe /i GlobalProtect.msi =" " Msiexec is an executable program that installs or configures a product from the command line. On systems running Microsoft Windows XP or a later OS, the maximum length of the string that you can use at the command prompt is 8,191 characters. Msiexec Example msiexec.exe /i GlobalProtect.msi /quiet PORTAL=”portal.acme.com” msiexec.exe /i GlobalProtect.msi CANCONTINUEIFPORTALCERTINVALID=”no” Description Install GlobalProtect in quiet mode (no user interaction) and configure the portal address. Install GlobalProtect with the option to prevent users from connecting to the portal if the certificate is not valid. For a complete list of settings and the corresponding default values, see Customizable Agent Settings. To set up the GlobalProtect agent to wrap third-party credentials on a Windows client from Msiexec, see Enable SSO Wrapping for Third-Party Credentials with the Windows Installer. Deploy Scripts Using the Windows Registry You can enable deployment of custom scripts to Windows endpoints using the Windows registry. You can configure the GlobalProtect agent to initiate and run a script for any or all of the following events: before and after establishing the tunnel, and before disconnecting the tunnel. To run the script at a particular event, reference the batch script from a command registry entry for that event. Depending on the configuration settings, the GlobalProtect agent can run a script before and after the agent establishes a VPN tunnel with the gateway, and before the agent disconnects from the VPN tunnel. Use the following workflow to get started using the Windows registry to customize agent settings for Windows clients. The registry settings that enable you to deploy scripts are supported in GlobalProtect clients running GlobalProtect agent 2.3 and later releases. STEP 1 | Open the Windows registry, and locate the GlobalProtect agent customization settings. Open the Windows registry (enter regedit in the command prompt) and go to the location of the key depending on when you want to execute scripts (pre/post connect or pre disconnect): HKEY_LOCAL_MACHINE\SOFTWARE\Palo Alto Networks\GlobalProtect\Settings\prevpn-connect HKEY_LOCAL_MACHINE\SOFTWARE\Palo Alto Networks\GlobalProtect\Settings\postvpn-connect 124 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 2017 Palo Alto Networks, Inc. HKEY_LOCAL_MACHINE\SOFTWARE\Palo Alto Networks\GlobalProtect\Settings\prevpn-disconnect If the key does not exist within the Settings key, create it (right-click Settings and select New > Key). STEP 2 | Enable the GlobalProtect agent to run scripts by creating a new String Value named command. The batch file specified here should contain the specific script (including any parameters passed to the script) that you want run on the device. For examples, see Windows OS Batch Script Examples. 1. If the command string does not already exist, create it (right-click the pre-vpn-connect, postvpn-connect, or pre-vpn-disconnect key, select New > String Value, and name it command). 2. Right click command and select Modify. 3. Enter the commands or script that the GlobalProtect agent should run. For example: %userprofile%\pre_vpn_connect.bat c: test_user STEP 3 | (Optional) Add additional registry entries as needed for each command. Create or modify registry strings and their corresponding values, including context, timeout, file, checksum, or error-msg. For additional information, see Customizable Agent Settings. Windows OS Batch Script Examples You can configure the GlobalProtect agent to initiate and run a script for any or all of the following events: before and after establishing the tunnel, and before disconnecting the tunnel. To run the script at a particular event, reference the batch script from a command registry entry for that event. The following examples show scripts you can run on Windows systems at pre-connect, post-connect, and pre-disconnect events: Example: Exclude Traffic from the VPN Tunnel on Windows Endpoints To exclude traffic from the VPN tunnel after establishing the VPN connection, reference the following script from a command registry entry for a post-vpn-connect event. This enables you to selectively exclude routes and to send all other traffic through the VPN tunnel. As a best practice, delete any exclude network routes that were previously added before adding the new exclude routes. In most cases, when a user moves between networks (such as when switching between Wi-Fi and a local network) the old network routes are GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 125 2017 Palo Alto Networks, Inc. automatically deleted. In the event that the old network routes persist, following this best practice ensures that traffic destined for the exclude routes will go through the gateway of the new network instead of the gateway of the old network. For a script that you can copy and paste, go here. @echo off REM Run this script (route_exclude) post-vpn-connect. REM Add exclude routes. This allows traffic to these network and hosts to go directly and not use the tunnel. REM Syntax: route_exclude ...

To do so, use the following syntax: msiexec.exe /i GlobalProtect.msi =" " 126 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 2017 Palo Alto Networks, Inc. Msiexec is an executable program that installs or configures a product from a command line. On systems running Microsoft Windows XP or a later release, the maximum length of the string that you can use at the command prompt is 8,191 characters. This limitation applies to the command line, individual environment variables (such as the USERPROFILE variable) that are inherited by other processes, and all environment variable expansions. If you run batch files from the command line, this limitation also applies to batch file processing. For example, to deploy scripts that run at specific connect or disconnect events, you can use syntax similar to the following examples: Example: Use Msiexec to Deploy Scripts that Run Before a Connect Event For a script that you can copy and paste, go here. msiexec.exe /i GlobalProtect.msi PREVPNCONNECTCOMMAND="%userprofile%\pre_vpn_connect.bat c: test_user" PREVPNCONNECTCONTEXT="user" PREVPNCONNECTTIMEOUT="60" PREVPNCONNECTFILE="C:\Users\test_user\pre_vpn_connect.bat" PREVPNCONNECTCHECKSUM="a48ad33695a44de887bba8f2f3174fd8fb01a46a19e3ec9078b011 8647ccf599" PREVPNCONNECTERRORMSG="Failed executing pre-vpn-connect action."

Or, for examples of batch scripts, see Windows OS Batch Script Examples. SSO Wrapping for Third-Party Credential Providers on Windows Clients On Windows 7 and Windows Vista clients, the GlobalProtect agent utilizes the Microsoft credential provider framework to support single sign-on (SSO). With SSO, the GlobalProtect credential provider wraps the Windows native credential provider, which enables GlobalProtect to use Windows login credentials to automatically authenticate and connect to the GlobalProtect portal and gateway. In some scenarios when other third-party credential providers also exist on the client, the GlobalProtect credential provider is unable to gather a user's Windows login credentials and, as a result, GlobalProtect fails to automatically connect to the GlobalProtect portal and gateway. If SSO fails, you can identify the third-party credential provider and then configure the GlobalProtect agent to wrap those third-party credentials, which enables users to successfully authenticate to Windows, GlobalProtect, and the thirdparty credential provider—all in a single step—using only their Windows login credentials when they log in to their Windows system. Optionally, you can configure Windows to display separate login tiles: one for each third-party credential provider and another for the native Windows login. This is useful when a third-party credential provider adds additional functionality in the login tile that does not apply to GlobalProtect. Use the Windows registry or the Windows Installer (Msiexec) to allow GlobalProtect to wrap third-party credentials: • Enable SSO Wrapping for Third-Party Credentials with the Windows Registry on page 128 • Enable SSO Wrapping for Third-Party Credentials with the Windows Installer on page 130 GlobalProtect SSO wrapping for third-party credential providers (CPs) is dependent on the third-party CP settings and, in some cases, GlobalProtect SSO wrapping might not work correctly if the third-party CP implementation does not allow GlobalProtect to successfully wrap their CP. Enable SSO Wrapping for Third-Party Credentials with the Windows Registry Use the following steps in the Windows registry to enable SSO to wrap third-party credentials on Windows 7 and Windows Vista clients. STEP 1 | Open the Windows registry and locate the globally unique identifier (GUID) for the third-party credential provider that you want to wrap. 1. From the command prompt, enter the command regedit to open the Windows registry. 2. Locate currently installed credential providers at the following location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion \Authentication\Credential Providers. 3. Copy the GUID key for the credential provider that you want to wrap (including the curly brackets— { and } —on either end of the GUID): 128 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 2017 Palo Alto Networks, Inc. STEP 2 | Enable SSO wrapping for third-party credential providers by adding the setting wrap-cp-guid to the GlobalProtect registry. 1. Go to the following Windows registry location: HKEY_LOCAL_MACHINE\SOFTWARE\Palo Alto Networks\ GlobalProtect: 2. Add a new String Value: 3. Enter values for the String Value: • Name: wrap-cp-guid • Value data: { } For the Value data field, the GUID value that you enter must be enclosed with curly brackets: { and }. The following is an example of what a third-party credential provider GUID in the Value data field might look like: {A1DA9BCC-9720-4921-8373-A8EC5D48450F} For the new String Value, wrap-cp-guid is displayed as the String Value’s Name and the GUID is displayed as the Data. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 129 2017 Palo Alto Networks, Inc. STEP 3 | Next Steps: • You can configure SSO wrapping for third-party credential providers successfully by completing steps 1 and 2. With this setup, the native Windows logon tile is displayed to users. Users click the tile and log in to the system with their Windows credentials and that single login authenticates the users to Windows, GlobalProtect, and the third-party credential provider. • (Optional) If you want to display two tiles to users at login, the native Windows tile and the tile for the third-party credential provider, continue to 4. STEP 4 | (Optional) Allow the third-party credential provider tile to be displayed to users at login. Add a second String Value with the Name filter-non-gpcp and enter no for the string’s Value data: With this string value added to the GlobalProtect settings, two login options are presented to users when logging in to their Windows system: the native Windows tile and the third-party credential provider’s tile. Enable SSO Wrapping for Third-Party Credentials with the Windows Installer Use the following options in the Windows Installer (Msiexec) to enable SSO to wrap third-party credential providers on Windows 7 and Windows Vista clients. • Wrap third-party credentials and display the native tile to users at login. Users click the tile and log in to the system with their native Windows credentials and that single login authenticates users to Windows, GlobalProtect, and the third-party credential provider. Use the following syntax from the Windows Installer (Msiexec): msiexec.exe /i GlobalProtect.msi WRAPCPGUID=”{guid_value}” FILTERNONGPCP=”yes” In the syntax above, the FILTERNONGPCP parameter simplifies authentication for the user by filtering the option to log in to the system using the third-party credentials. • If you would like users to have the option to log in with the third-party credentials, use the following syntax from the Msiexec: msiexec.exe /i GlobalProtect.msi WRAPCPGUID=”{guid_value}” FILTERNONGPCP=”no” In the syntax above, the FILTERNONGPCP parameter is set to “no”, which filters out the third-party credential provider’s logon tile so that only the native tile displays. In this case, both the native Windows tile and the third-party credential provider tile is displayed to users when logging in to the Windows system. 130 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 2017 Palo Alto Networks, Inc. Deploy Agent Settings to Mac Clients Use the Mac global plist (property list) file to set GlobalProtect agent customization settings for or to deploy scripts to Mac endpoints. • Deploy Agent Settings in the Mac Plist • Deploy Scripts Using the Mac Plist • Mac OS Script Examples Deploy Agent Settings in the Mac Plist You can set the GlobalProtect agent customization settings in the Mac global plist (Property list) file. This enables deployment of GlobalProtect agent settings to Mac endpoints prior to their first connection to the GlobalProtect portal. On Mac systems, plist files are either located in /Library/Preferences or in ~/Library/ Preferences. The tilde ( ~ ) symbol indicates that the location is in the current user's home folder. The GlobalProtect agent on a Mac client first checks for the GlobalProtect plist settings. If the plist does not exist at that location, the GlobalProtect agent searches for plist settings in ~/Library/Preferences. In addition to using the Mac plist to deploy GlobalProtect agent settings, you can enable the GlobalProtect agent to collect specific Mac plist information from clients. You can then monitor the data and add it to a security rule as matching criteria. Device traffic that matches registry settings you have defined can be enforced according to the security rule. Additionally, you can set up custom checks to Collect Application and Process Data From Clients. • Open the GlobalProtect plist file and locate the GlobalProtect agent customization settings. Use Xcode or an alternate plist editor to open the plist file: /Library/Preferences/com.paloaltonetworks.GlobalProtect.settings.plist Then go to: /Palo Alto Networks/GlobalProtect/Settings If the Settings dictionary does not exist, create it. Then add each key to the Settings dictionary as a string. • Set the portal name. If you don’t want the user to manually enter the portal address even for the first connection, you can pre-deploy the portal address through the Mac plist. Under the PanSetup dictionary, configure an entry for Portal. • Deploy various settings to the Mac client from the Mac plist, including configuring the connect method for the GlobalProtect agent. View Customizable Agent Settings for a full list of the keys and values that you can configure using the Mac plist. Deploy Scripts Using the Mac Plist When a user connects to the GlobalProtect gateway for the first time, the GlobalProtect agent downloads a configuration file and stores agent settings in a GlobalProtect Mac property file (plist). In addition to making GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 131 2017 Palo Alto Networks, Inc. changes to the agent settings, you use the Mac plist to deploy scripts at any or all of the following events: before and after establishing the tunnel, and before disconnecting the tunnel. Use the following workflow to get started using the Mac plist to deploy scripts to Mac endpoints. The Mac plist settings that enable you to deploy scripts are supported in GlobalProtect clients running GlobalProtect agent 2.3 and later releases. STEP 1 | (Clients running Mac OS X 10.9 or a later OS) Flush the settings cache. This prevents the OS from using the cached preferences after making changes to the plist. To clear the default preferences cache, run the killall cfprefsd command from a Mac terminal. STEP 2 | Open the GlobalProtect plist file, and locate or create the GlobalProtect dictionary associated with the connect or disconnect event. The dictionary under which you will add the settings will determine when the GlobalProtect agent runs the script(s). Use Xcode or an alternate plist editor to open the plist file (/Library/Preferences/ com.paloaltonetworks.GlobalProtect.settings.plist) and go to the location of the dictionary: • /Palo Alto Networks/GlobalProtect/Settings/pre-vpn-connect • /Palo Alto Networks/GlobalProtect/Settings/post-vpn-connect • /Palo Alto Networks/GlobalProtect/Settings/pre-vpn-disconnect If Settings dictionary does not exist, create it. Then, in Settings, create a new dictionary for the event or events at which you want to run scripts. STEP 3 | Enable the GlobalProtect agent to run scripts by creating a new String named command. The value specified here should reference the shell script (and the parameters to pass to the script) that you want run on your devices. See Mac OS Script Examples on page 133. If the command string does not already exist, add it to the dictionary and specify the script and parameters in the Value field, for example: $HOME\pre_vpn_connect.sh /Users/username username Environmental variables are supported. As a best practice, specify the full path in commands. STEP 4 | (Optional) Add additional settings related to the command, including administrator privileges, a timeout value for the script, checksum value for the batch file, and an error message to display if the command fails to execute successfully. Create or modify additional strings in the plist (context, timeout, file, checksum, and/or errormsg) and enter their corresponding values. For additional information, see Customizable Agent Settings on page 115. STEP 5 | Save the changes to the plist file. Save the plist. 132 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 2017 Palo Alto Networks, Inc. Mac OS Script Examples You can configure the GlobalProtect agent to initiate and run a script for any or all of the following events: before and after establishing the tunnel, and before disconnecting the tunnel. To run the script at a particular event, reference the shell script from a command plist entry for that event. The following topics show examples of scripts that you can run at pre-connect, post-connect and pre-disconnect events: Example: Terminate All Established SSH Sessions on Mac Endpoints To force termination of all established SSH sessions before setting up the VPN tunnel, reference the following script from a command plist entry for a pre-vpn-connect event. Similarly, you can re-establish the sessions after establishing the GlobalProtect VPN tunnel by using a script that you reference from the command plist entry for a post-vpn-connect event. This can be useful if you want to force all SSH traffic to traverse the GlobalProtect VPN tunnel. #!bin/bash # Identify all SSH sessions and force kill them ps | grep ssh | grep -v grep | awk '{ print $1 }' | xargs kill -9 Example: Mount a Network Share on Mac Endpoints To mount a network share after establishing a VPN connection, reference the following script from a command plist entry for a post-vpn-connect event: For a script that you can copy and paste, go here. #!/bin/bash mkdir $1 mount -t smbfs //username:password@10.101.2.17/shares/Departments/Engineering/ SW_eng/username/folder $1 sleep 1 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients © 133 2017 Palo Alto Networks, Inc. 134 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clients GlobalProtect Clientless VPN GlobalProtect Clientless VPN provides secure remote access to common enterprise web applications. Users have the advantage of secure access from SSL-enabled web browsers without installing GlobalProtect client software. This is useful when you need to enable partner or contractor access to applications, and to safely enable unmanaged assets, including personal devices. You can configure the GlobalProtect portal landing page to provide access to web applications based on users and user groups and also allow single-sign on to SAML-enabled applications.

Clientless VPN Overview When you configure Clientless VPN, remote users can log in to the GlobalProtect portal using a web browser and launch the web applications you publish for the user. Based on users or user groups, you can allow users to access a set of applications that you make available to them, or allow them to access additional corporate applications by entering a custom application URL. After logging in to the portal, users see a published applications page with a list of web applications they can launch. (You can use the default applications landing page on the GlobalProtect portal or create a custom landing page for your enterprise.) Figure 1: Applications Landing Page for Clientless VPN Because this page replaces the default portal landing page, it includes a link to the GlobalProtect agent download page. If configured, users can also select Application URL and enter URLs to launch additional, unpublished corporate web applications. When you configure only one web application (and disable access to unpublished applications), instead of taking the user to the published applications page, the application will launch automatically as soon as the user logs in. If you do not configure GlobalProtect Clientless VPN, users will see the agent software download page when they log in to the portal. When you configure GlobalProtect Clientless VPN, you need security policies to allow traffic from GlobalProtect endpoints to the security zone associated with the GlobalProtect portal that hosts the published applications landing page and security policies to allow user-based traffic from the GlobalProtect portal zone to the security zone where the published application servers are hosted. The security policies you define control which users have permission to use each published application.

Refer to Active Licenses and Subscriptions. • Install the GlobalProtect Clientless VPN dynamic update (see Install Content and Software Updates). • As a best practice, configure a separate FQDN for the GlobalProtect portal that hosts Clientless VPN. Do not use the same FQDN as the PAN-OS Web Interface. • Host the GlobalProtect portal on the standard SSL port (TCP port 443). Non-standard ports are not supported. STEP 2 | Configure the applications that are available using GlobalProtect Clientless VPN. The GlobalProtect portal displays these applications on the landing page that users see when they log in (the applications landing page). 1. Select Network > GlobalProtect > Clientless Apps and Add one or more applications. For each application, specify the following: • Name—A descriptive name for the application (up to 31 characters). The name is case-sensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores. • Location (for a firewall that is in multiple virtual system mode)—the virtual system (vsys) where the Clientless VPN applications are available. For a firewall that is not in multi-vsys mode, the Location field does not appear. • Application Home URL—The URL where the web application is located (up to 4095 characters). • Application Description (Optional)—A brief description of the application (up to 255 characters). • Application Icon (Optional)—An icon to identify the application on the published application page. You can browse to upload the icon. 2. Click OK. STEP 3 | (Optional). Create groups to manage sets of web applications. Clientless App Groups are useful if you want to manage multiple collections of applications and provide access based on user groups. For example, financial applications for the G&A team or developer applications for the Engineering team. 1. Select Network > GlobalProtect > Clientless App Groups. Add a new Clientless VPN application group and specify the following: • Name—A descriptive name for the application group (up to 31 characters). The name is casesensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores. • Location (for a firewall that is in multiple virtual system mode)—the virtual system (vsys) where the Clientless VPN application group is available. For a firewall that is not in multi-vsys mode, the Location field does not appear. 2. In the Applications area, Add applications to the group. You can select from the list of existing Clientless VPN applications or define a New Clientless App. 3. Click OK. 140 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clientless VPN © 2017 Palo Alto Networks, Inc. STEP 4 | Configure the GlobalProtect portal to provide the Clientless VPN service. 1. Select Network > GlobalProtect > Portal and select an existing portal configuration or Add a new portal. Refer to Set Up Access to the GlobalProtect Portal. 2. In the Authentication tab, you can: • (Optional) Create a new client authentication specifically for Clientless VPN. In this case, choose Browser as the OS for Client Authentication. • Use an existing client authentication. 3. In Clientless > General, select Clientless VPN to enable the portal service and configure the following: • Specify a Hostname (IP address or fully-qualified domain name) for the GlobalProtect portal that hosts the applications landing page. This hostname is used for rewriting application URLs. (For more information on URL rewriting, refer to 8). If you use Network Address Translation (NAT) to provide access to the GlobalProtect portal, the IP address or FQDN you enter must match (or resolve to) the NAT IP address for the GlobalProtect portal (the public IP address). Because users cannot access the GlobalProtect portal on a custom port, the pre-NAT port must also be TCP port 443. • Specify a Security Zone. This zone is used as a source zone for the traffic between the firewall and the applications. Security rules defined from this zone to the application zone determine which applications can be accessed. • Select a DNS Proxy server or configure a New DNS Proxy. GlobalProtect will use this proxy to resolve application names. Refer to DNS Proxy Object. • Login Lifetime—Specify the maximum hours or minutes that a Clientless VPN session is valid. The typical session time is 3 hours. The range for hours is 1-24; the range for minutes is 60-1440. After the session expires, users must re-authenticate and start a new Clientless VPN session. • Inactivity Timeout—Specify the number of hours or minutes that a Clientless VPN session can remain idle. The typical inactivity timeout is 30 minutes. The range for hours is 1-24; the range for minutes is 5 to 1440. If there is no user activity during the specified amount of time, users must re-authenticate and start a new Clientless VPN session. • Max User—Specify the maximum number of users who can be logged into the portal at the same time. If no value is specified, then endpoint capacity is assumed. If the endpoint capacity is unknown, then a capacity of 50 users is assumed. When the maximum number of users is reached, additional Clientless VPN users cannot log in to the portal. STEP 5 | Map users and user groups to applications. This mapping controls which applications users or user groups can launch from a GlobalProtect Clientless VPN session. The GlobalProtect portal uses the user/user group settings that you specify to determine which configuration to deliver to the GlobalProtect Clientless VPN user that connects. If you have multiple configurations, make sure they are ordered properly and map to all of the required applications, as the portal looks for a configuration match starting from the top of the list. As soon as the portal finds a match, it delivers the configuration to the GlobalProtect Clientless VPN user. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clientless VPN © 141 2017 Palo Alto Networks, Inc. Publishing an application to a user/user group or allowing them to launch unpublished applications does not imply that they can access those applications. Controlling access to applications (published or not) is done using security policies. You must configure group mapping (Device > User Identification > Group Mapping Settings) before you can select the groups. 1. In the Applications tab, Add an Applications to User Mapping to match users with published applications. • Name—Enter a name for the mapping (up to 31 characters). The name is case-sensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores. • Display application URL address bar—Select this option to display an application URL address bar from which users can launch applications that are not published on the applications landing page. When enabled, users can click the Application URL link on the page and specify a URL. 2. Specify the Source Users. You can Add individual users or user groups to which the current application configuration applies. These users have permission to launch the configured applications using a GlobalProtect Clientless VPN. In addition to users and groups, you can specify when these settings apply to the users or groups: • any—The application configuration applies to all users (no need to Add users or user groups). • select—The application configuration applies only to users and user groups you Add to this list. 3. Add individual applications or application groups to the mapping. The Source Users you included in the configuration can use GlobalProtect Clientless VPN to link to the applications you add. STEP 6 | Specify the security settings for a Clientless VPN session. 1. In the Crypto Settings tab, specify the authentication and encryption algorithms for the SSL sessions between the firewall and the published applications. • Protocol Versions—Select the required minimum and maximum TLS/SSL versions. The higher the TLS version, the more secure the connection. Choices include SSLv3, TLSv1.0, TLSv1.1, or TLSv1.2. 142 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clientless VPN © 2017 Palo Alto Networks, Inc. • Key Exchange Algorithms—Select the supported algorithm types for key exchange. Choices are: RSA, Diffie-Hellman (DHE), or Elliptic Curve Ephemeral Diffie-Hellman (ECDHE). • Encryption Algorithms—Select the supported encryption algorithms. AES128 or higher is recommended. • Authentication Algorithms—Select the supported authentication algorithms. Choices are: MD5, SHA1, SHA256, or SHA384. SHA256 or higher is recommended. 2. Select the action to take when the following issues occur with a server certificate presented by an application: • Block sessions with expired certificate—If the server certificate has expired, block access to the application. • Block sessions with untrusted issuers—If the server certificate is issued from an untrusted certificate authority, block access to the application. • Block sessions with unknown certificate status—If the OCSP or CRL service returns a certificate revocation status of unknown, block access to the application. • Block sessions on certificate status check timeout—If the certificate status check times out before receiving a response from any certificate status service, block access to the application. STEP 7 | (Optional) Specify one or more proxy server configurations to access the applications. Only basic authentication to the proxy is supported (username and password). If users need to reach the applications through a proxy server, specify a Proxy Server. You can add multiple proxy server configurations, one for each set of domains. • Name—A label (up to 31 characters) to identify the proxy server configuration. The name is casesensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores. • Domains—Add the domains served by the proxy server. You can use a wild card character (*) at the beginning of the domain name to indicate multiple domains. • Use Proxy—Select to assign a proxy server to provide access to the domains. • Server—Specify the IP address or host name of the proxy server. • Port—Specify a port for communication with the proxy server. • User and Password—Specify the User and Password credentials needed to log in to the proxy server. Specify the password again for verification. STEP 8 | (Optional) Specify any special treatment for application domains. The Clientless VPN acts as a reverse proxy and modifies web pages returned by the published web applications. It rewrites all URLs and presents a rewritten page to remote users such that when they access any of those URLs, the requests go through GlobalProtect portal. In some cases, the application may have pages that do not need to be accessed through the portal (for example, the application may include a stock ticker from yahoo.finance.com). You can exclude these pages. In the Advanced Settings tab, Add domain names, host names, or IP addresses to the Rewrite Exclude Domain List. These domains are excluded from rewrite rules and cannot be rewritten. Paths are not supported in host and domain names. The wildcard character (*) for host names and domain names can only appear at the beginning of the name (for example, *.etrade.com). STEP 9 | Save the portal configuration. 1. Click OK twice. 2. Commit your changes. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clientless VPN © 143 2017 Palo Alto Networks, Inc. STEP 10 | Configure a Security policy rule to enable users to access the published applications. You need security policies for the following: • Make the GlobalProtect portal which hosts Clientless VPN reachable from the Internet. This is traffic from Untrust or Internet Zone to the zone where you host the Clientless VPN portal. • Allow Clientless VPN users to reach the Internet. This is traffic from the Clientless VPN zone to the Untrust or Internet Zone. • Allow Clientless VPN users to reach corporate resources. This is traffic from the Clientless VPN zone to the Trust or Corp Zone. The security policies you define control which users have permission to use each published application. For the security zone where the published application servers are hosted, make sure Enable User Identification is set in order to create user-based rules for accessing published applications. By default Service/URL in Security Policy Rule is set application-default. Clientless VPN will not work for HTTPS sites with this default setting. Change Service/URL to include both service-http and service-https. • When you configure a proxy server to access Clientless VPN applications, make sure you include the proxy IP address and port in the security policy definition. When applications are accessed through a proxy server, only security policies defined for the proxy IP address and port are applied. 144 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Clientless VPN © 2017 Palo Alto Networks, Inc. Troubleshoot Clientless VPN Because this feature involves dynamic re-writing of HTML applications, the HTML content for some applications may not re-write correctly and break the application.

Mobile Endpoint Management Overview As mobile endpoints become more powerful, end users increasingly rely on them to perform business tasks. However, these same endpoints that access your corporate network also connect to the internet without protection against threats and vulnerabilities. By using a third-party mobile endpoint management system —such as a mobile device management (MDM) or enterprise mobility management (EMM) system—you can easily manage both company-provisioned and employee-owned devices (such as in a BYOD environment). A mobile endpoint management system simplifies the administration of mobile endpoints by enabling you to automatically deploy your corporate account configuration and VPN settings to compliant endpoints. You can also use your mobile endpoint management system for remediation of security breaches by interacting with an endpoint that has been compromised. This protects both corporate data as well as personal end user data. For example, if an end user loses an endpoint, you can remotely lock the endpoint from the mobile endpoint management system or even wipe the endpoint (either completely or selectively). In addition to the account provisioning and remote device management functions that a mobile endpoint management system can provide, when integrated with your existing GlobalProtect™ VPN infrastructure, you use host information that the endpoint reports to enforce security policies for access to apps through the GlobalProtect gateway. You can also use the monitoring tools that are built into the Palo Alto nextgeneration firewall to monitor mobile endpoint traffic. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Mobile Endpoint Management © 151 2017 Palo Alto Networks, Inc. Set Up a Mobile Endpoint Management System To set up a mobile endpoint management system, use the following workflow: STEP 1 | Set up the GlobalProtect Infrastructure. 1. Create Interfaces and Zones for GlobalProtect on page 15. 2. Enable SSL Between GlobalProtect Components on page 17. 3. Set up GlobalProtect User Authentication. Refer to About GlobalProtect User Authentication on page 27. 4. Enable Group Mapping on page 63. 5. Configure a GlobalProtect Gateway on page 72. 6. Activate Licenses for each firewall running a gateway(s) that supports the GlobalProtect app on mobile endpoints. 7. Set Up Access to the GlobalProtect Portal on page 83. STEP 2 | Set up the mobile endpoint management system and decide whether to support only corporate-issued endpoints or both corporate-issued and personal endpoints. See the instructions for your mobile endpoint management system, mobile device management (MDM) system, or enterprise mobility management (EMM) system. STEP 3 | Obtain the GlobalProtect app for mobile endpoints. • App store—Download and Install the GlobalProtect Mobile App on page 109 • AirWatch—Deploy the GlobalProtect Mobile App Using AirWatch on page 153 • Other third-party mobile endpoint management system—See the instructions from your vendor on how to deploy apps to managed endpoints.

As with other remote hosts running the GlobalProtect agent, the mobile app provides secure access to your corporate network over an IPSec or SSL VPN tunnel. The app connects to the gateway that is closest to the end user’s current location. In addition, traffic to and from the mobile endpoint is automatically subject to the same security policy enforcement as other hosts on your corporate network. Like the GlobalProtect agent, the app collects information about the host configuration and can use this information for enhanced HIP-based security policy enforcement. There are two primary methods for installing the GlobalProtect app: You can you can install the app directly from the app store for your endpoint (see Download and Install the GlobalProtect Mobile App on page 109); or, deploy the app from a third-party mobile endpoint management system (such as AirWatch) and transparently push the app to your managed endpoints. With AirWatch, you can deploy the GlobalProtect app to managed endpoints that have enrolled with AirWatch. Endpoints running iOS or Android must download the AirWatch agent to enroll with the AirWatch EDM. Windows 10 endpoints do not require the AirWatch agent but require you to configure enrollment on the endpoint. After you deploy the app, configure and deploy a VPN profile to set up the GlobalProtect app for the end user automatically. STEP 1 | Before you begin, ensure that the endpoints to which you want to deploy the GlobalProtect app are enrolled with AirWatch: • Android and iOS—Download the AirWatch agent and following the prompts to enroll. • Windows Phone and Windows 10 UWP—Configure the Windows 10 UWP endpoint to enroll with AirWatch (from the endpoint, select Settings > Accounts > Work access > Connect). STEP 2 | From AirWatch, select Apps & Books > Public > Add Application. STEP 3 | Select the organization group by which this app will be managed. STEP 4 | Select the Platform, either Apple iOS, Android, or Windows Phone.

Configure the GlobalProtect App for Windows 10 UWP Using AirWatch Using the GlobalProtect app for Windows10UWP as the secure connection between the endpoint and the firewall allows consistent inspection of traffic and enforcement of network security policy for threat prevention. The GlobalProtect app for Windows 10 UWP supports the following configurations using AirWatch: • Per-App VPN—Specifies which managed apps on the endpoint can send traffic through the secure tunnel. Unmanaged apps will continue to connect directly to the Internet instead of through the secure connection. • Device-Level VPN—Sends all traffic that matches specific filters (such as port and IP address) through the VPN irrespective of app. Device-level VPN configurations also support the ability to force the secure connection to be Always On. For even tighter security requirements, you can enable the VPN Lockdown option which both forces the secure connection to always be on and connected and disables network access when the app is not connected. This configuration is similar to the Enforce GlobalProtect for Network Access option that you would typically configure in a GlobalProtect portal configuration. Because AirWatch does not yet list GlobalProtect as an official connection provider for Windows endpoints, you must select an alternate VPN provider, edit the settings for the GlobalProtect app, and import the configuration back into the VPN profile as described in the following workflow. STEP 1 | Download the GlobalProtect app for Windows 10 UWP: • Deploy the GlobalProtect Mobile App Using AirWatch. • Download the GlobalProtect app directly from the Microsoft Store. STEP 2 | From the AirWatch console, add a new Windows 10 UWP profile: GLOBALPROTECT ADMINISTRATOR'S GUIDE | Mobile Endpoint Management © 161 2017 Palo Alto Networks, Inc. Navigate to Devices > Profiles > List View. Select Add > Add Profile. Select Windows as the platform and Windows Phone as the configuration type. Configure General profile settings such as a meaningful Name for this configuration and a brief Description of the profile that indicates its purpose. 5. Save and Publish this profile to the assigned Smart Groups. 1. 2. 3. 4. STEP 3 | To configure the VPN connection settings, select VPN and then click Configure. STEP 4 | Select Configure Connection Info, including: • Connection Name—Enter the name of the connection name that the endpoint will display. • Connection Type—Select an alternate provider (do not select IKEv2, L2TP, PPTP, or Automatic as these do not have the associated vendor settings required for the GlobalProtect VPN profile). You must select the alternate vendor because AirWatch does not yet list GlobalProtect as an official connection provider for Windows endpoints. • Server—Enter the hostname or IP address of the GlobalProtect portal to which to connect. STEP 5 | Configure the authentication settings for the VPN connection: 1. Select the Authentication Type to choose the method to authenticate end users. 2. To permit GlobalProtect to save user credentials, enable Remember Credentials in the Policies area. STEP 6 | Configure VPN traffic rules to apply device wide or on a per-app basis: • Add New Per-App VPN Rule—Specify rules for specific legacy apps (typically .exe files) or modern apps (typically downloaded from the Microsoft Store) that determine whether to automatically establish the VPN connection when the app is launched and whether to send app traffic through the VPN. You can also configure specific traffic filters to route only app traffic through the VPN if it matches match criteria such as IP address and port. • Add New Device-Wide VPN Rule—Specify routing filters to send traffic matching a specific route through the VPN. These rules are not bound by application and are evaluated across the endpoint. If the traffic matches the match criteria, it is routed through the VPN. STEP 7 | (Device-level VPN only) If desired, configure your preference of Always-On connection: 1. To maintain the VPN connection always, enable either of the following options: • Always On—Force the secure connection to be always on. • VPN Lockdown—Force the secure connection to be always on and connected, and disable the network access when the app is not connected. The VPN Lockdown option in AirWatch is similar to the Enforce GlobalProtect for Network Access option that you would configure in a GlobalProtect portal configuration. 2. Specify Trusted Network addresses if you want GlobalProtect to connect only when it detects a trusted network connection. 3. Save & Publish your changes. STEP 8 | To adapt the configuration for GlobalProtect, edit the VPN profile in XML. To minimize additional edits in the raw XML, review the settings in your VPN profile before you export the configuration. If you need to change a setting after you export the VPN profile, you can make the changes in the raw XML or, you can update the setting in the VPN profile and perform this step again. 162 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Mobile Endpoint Management © 2017 Palo Alto Networks, Inc. 1. In the Devices > Profiles > List View, select the radio button next to the new profile you added in the previous steps, and then select >XML at the top of the table. AirWatch opens the XML view of the profile. 2. Export the profile and then open it in a text editor of your choice. 3. Edit the following settings for GlobalProtect: • In the LoclURI element that specifies the PluginPackageFamilyName, change the element to: ./Vendor/MSFT/VPNv2/PaloAltoNetworks/PluginProfile/ PluginPackageFamilyName • In the Data element that follows, change the value to: PaloAltoNetworks.GlobalProtect_rn9aeerfb38dg 1. 2. 3. 4. 5. Save your changes to the exported profile. Return to AirWatch and the Devices > Profiles > List View. Create (select Add > Add Profile > Windows > Windows Phone) and name a new profile. Select Custom Settings > Configure, and then copy and paste the edited configuration. Save & Publish your changes. STEP 9 | Clean up the original profile: Select the original profile from the Devices > Profiles > List View, select More Actions > Deactivate. AirWatch moves the profile to the Inactive list. STEP 10 | Test the configuration. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Mobile Endpoint Management © 163 2017 Palo Alto Networks, Inc. Manage the GlobalProtect App Using a ThirdParty MDM You can use any third-party mobile device management system, such as a mobile device management (MDM) system, that manages an Android or iOS mobile endpoint to deploy and configure the GlobalProtect app. • Manage the GlobalProtect App for iOS Using a Third-Party MDM System • Configure the GlobalProtect App for iOS on page 164 • Example: GlobalProtect iOS App Device-Level VPN Configuration on page 165 • Example: GlobalProtect iOS App App-Level VPN Configuration on page 166 • Manage the GlobalProtect App for Android Using a Third-Party MDM System • Configure the GlobalProtect App for Android on page 168 • Example: Set VPN Configuration on page 169 • Example: Remove VPN Configuration on page 169 Configure the GlobalProtect App for iOS While a third-party MDM system allows you to push configuration settings that allow access to your corporate resources and provides a mechanism for enforcing device restrictions, it does not secure the connection between the mobile endpoint and services it connects to. To enable the client to establish secure tunnel connections, you must enable VPN support on the endpoint.

On Android devices, traffic is routed through the VPN tunnel according to the access routes configured on the GlobalProtect gateway. From your third-party MDM that manages Android for Work devices, you can further refine the traffic that is routed though the VPN tunnel. In an environment where the device is corporately owned, the device owner manages the entire device including all the apps installed on that device. By default, all installed apps can send traffic through the VPN tunnel according to the access routes defined on the gateway. In a bring-your-own-device (BYOD) environment, the device is not corporately owned and uses a Work Profile to separate business and personal apps. By default only managed apps in the Work Profile can send traffic through the VPN tunnel according to the access routes defined on the gateway. Apps installed on the personal side of the device can not send traffic through the VPN tunnel set by the managed GlobalProtect app installed in the Work Profile. To route traffic from an even smaller set of apps, you can enable Per-App VPN so that GlobalProtect only routes traffic from specific managed apps. For Per-App VPN, you can whitelist or blacklist specific managed apps from having their traffic routed through the VPN tunnel. As part of the VPN configuration, you can also specify how the user connects to the VPN. When you configure the VPN connection method as user-logon, the GlobalProtect app will establish a connection automatically. When you configure the VPN connection method as on-demand, users can initiate a connection manually when attempting to connect to the VPN remotely. The VPN connect method defined in the MDM takes precedence over the connect method defined in the GlobalProtect portal configuration. Removing the VPN configuration automatically restores the GlobalProtect app to the original configuration settings. To configure the GlobalProtect app for Android, configure the following Android App Restrictions.

With today’s workforce becoming more and more mobile, often requiring access to corporate resources from a variety of locations—airports, coffee shops, hotels—and from a variety of devices—both companyprovisioned and personal—you must logically extend your network’s security out to your endpoints to ensure comprehensive and consistent security enforcement. The GlobalProtect™ Host Information Profile (HIP) feature enables you to collect information about the security status of your end hosts—such as whether they have the latest security patches and antivirus definitions installed, whether they have disk encryption enabled, whether the device is jailbroken or rooted (mobile devices only), or whether it is running specific software you require within your organization, including custom applications—and base the decision as to whether to allow or deny access to a specific host based on adherence to the host policies you define. The following topics provide information about the use of host information in policy enforcement. It includes the following sections: > > > > > About Host Information on page 173 Configure HIP-Based Policy Enforcement on page 177 Collect Application and Process Data From Clients on page 184 Block Device Access on page 190 Configure Windows User-ID Agent to Collect Host Information on page 192 171 172 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. About Host Information One of the jobs of the GlobalProtect agent is to collect information about the host it is running on. The agent then submits this host information to the GlobalProtect gateway upon successfully connecting. The gateway matches this raw host information submitted by the agent against any HIP objects and HIP profiles you have defined. If it finds a match, it generates an entry in the HIP Match log. Additionally, if it finds a HIP profile match in a policy rule, it enforces the corresponding security policy. Using host information profiles for policy enforcement enables granular security that ensures that the remote hosts accessing your critical resources are adequately maintained and in adherence with your security standards before they are allowed access to your network resources. For example, before allowing access to your most sensitive data systems, you might want to ensure that the hosts accessing the data have encryption enabled on their hard drives. You can enforce this policy by creating a security rule that only allows access to the application if the client system has encryption enabled. In addition, for clients that are not in compliance with this rule, you could create a notification message that alerts users as to why they have been denied access and links them to the file share where they can access the installation program for the missing encryption software (of course, to allow the user to access that file share you would have to create a corresponding security rule allowing access to the particular share for hosts with that specific HIP profile match). • • • • What Data Does the GlobalProtect Agent Collect? on page 173 How Does the Gateway Use the Host Information to Enforce Policy? on page 175 How Do Users Know if Their Systems are Compliant? on page 176 How Do I Get Visibility into the State of the End Clients? on page 176 What Data Does the GlobalProtect Agent Collect? By default, the GlobalProtect agent collects vendor-specific data about the end user security packages that are running on the computer (as compiled by the OPSWAT global partnership program) and reports this data to the GlobalProtect gateway for use in policy enforcement. Because security software must continually evolve to ensure end user protection, your GlobalProtect gateway licenses also enable you to get dynamic updates for the GlobalProtect data file with the latest patch and software versions available for each package. While the agent collects a comprehensive amount of data about the host it is running on, you may have additional software that you require your end-users to run in order to connect to your network or to access certain resources. In this case, you can define custom checks that instruct the agent to collect specific registry information (on Windows clients), preference list (plist) information (on Mac OS clients), or to collect information about whether or not specific services are running on the host. The agent collects data about the following categories of information by default, to help to identify the security state of the host: Table 6: Table: Data Collection Categories Category Data Collected General Information about the host itself, including the hostname, logon domain, operating system, client version, and, for Windows systems, the domain to which the machine belongs. For Windows clients’ domain, the GlobalProtect agent collects the domain defined for GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 173 2017 Palo Alto Networks, Inc. Category Data Collected ComputerNameDnsDomain, which is the DNS domain assigned to the local computer or the cluster associated with the local computer. This data is what is displayed for the Windows clients’ Domain in the HIP Match log details (Monitor > HIP Match). Patch Management Information about any patch management software that is enabled and/or installed on the host and whether there are any missing patches. Firewall Information about any client firewalls that are installed and/or enabled on the host. Antivirus Information about any antivirus software that is enabled and/or installed on the host, whether or not real-time protection is enabled, the virus definition version, last scan time, the vendor and product name. GlobalProtect uses OPSWAT technology to detect and assess thirdparty security applications on the endpoint. By integrating with the OPSWAT OESIS framework, GlobalProtect enables you to assess the compliance state of the endpoint. For example, you can define HIP objects and HIP profiles that verify the presence of a specific version of Antivirus software from a specific vendor on the endpoint and also ensure that it has the latest virus definition files. Anti-Spyware Information about any anti-spyware software that is enabled and/or installed on the host, whether or not real-time protection is enabled, the virus definition version, last scan time, the vendor and product name. Disk Backup Information about whether disk backup software is installed, the last backup time, and the vendor and product name of the software. Disk Encryption Information about whether disk encryption software is installed, which drives and/or paths are configured for encryption, and the vendor and product name of the software. Data Loss Prevention Information about whether data loss prevention (DLP) software is installed and/or enabled for the prevention sensitive corporate information from leaving the corporate network or from being stored on a potentially insecure device. This information is only collected from Windows clients. Mobile Devices Information about the mobile device, including the device name, logon domain, operating system, app version, and the mobile device network information to which the device is connected. In addition, GlobalProtect collects whether the device is rooted or jailbroken. To collect mobile device attributes and utilize them in HIP enforcement policies, GlobalProtect requires 174 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. Category Data Collected an MDM server. GlobalProtect currently supports HIP integration with the AirWatch MDM server. For devices managed by AirWatch, host information collected by the GlobalProtect app can be supplemented with additional information collected from the AirWatch service. Refer to Configure Windows User-ID Agent to Collect Host Information for a list of attributes that can be retrieved from AirWatch. You can exclude certain categories of information from being collected on certain hosts (to save CPU cycles and improve client response time). To do this, you create a client configuration on the portal excluding the categories you are not interested in. For example, if you do not plan to create policy based on whether or not client systems run disk backup software, you can exclude that category and the agent will not collect any information about disk backup. You can also choose to exclude collecting information from personal devices in order to allow for user privacy. This can include excluding device location and a list of apps installed on the device that are not managed by a third-party mobile device manager. How Does the Gateway Use the Host Information to Enforce Policy? While the agent gets the information about what information to collect from the client configuration downloaded from the portal, you define which host attributes you are interested in monitoring and/or using for policy enforcement by creating HIP objects and HIP profiles on the gateway(s): • HIP Objects—Provide the matching criteria to filter out the host information you are interested in using to enforce policy from the raw data reported by the agent. For example, while the raw host data may include information about several antivirus packages that are installed on the client you may only be interested in one particular application that you require within your organization. In this case, you would create a HIP object to match the specific application you are interested in enforcing. The best way to determine what HIP objects you need is to determine how you will use the host information you collect to enforce policy. Keep in mind that the HIP objects themselves are merely building blocks that allow you to create the HIP profiles that are used in your security policies. Therefore, you may want to keep your objects simple, matching on one thing, such as the presence of a particular type of required software, membership in a specific domain, or the presence of a specific client OS. By doing this, you will have the flexibility to create a very granular (and very powerful) HIPaugmented policy. • HIP Profiles—A collection of HIP objects that are to be evaluated together, either for monitoring or for security policy enforcement. When you create your HIP profiles, you can combine the HIP objects you previously created (as well as other HIP profiles) using Boolean logic such that when a traffic flow is evaluated against the resulting HIP profile it will either match or not match. If there is a match, the corresponding policy rule will be enforced; if there is not a match, the flow will be evaluated against the next rule, as with any other policy matching criteria. Unlike a traffic log—which only creates a log entry if there is a policy match—the HIP Match log generates an entry whenever the raw data submitted by an agent matches a HIP object and/or a HIP profile you have defined. This makes the HIP Match log a good resource for monitoring the state of the hosts on your network over time—before attaching your HIP profiles to security policies—in order to help you determine exactly what policies you believe need enforcement. See Configure HIP-Based Policy Enforcement on page 177 for details on how to create HIP objects and HIP profiles and use them as policy match criteria. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 175 2017 Palo Alto Networks, Inc. How Do Users Know if Their Systems are Compliant? By default, end users are not given any information about policy decisions that were made as a result of enforcement of a HIP-enabled security rule. However, you can enable this functionality by defining HIP notification messages to display when a particular HIP profile is matched and/or not matched. The decision as to when to display a message (that is, whether to display it when the user’s configuration matches a HIP profile in the policy or when it doesn’t match it), depends largely on your policy and what a HIP match (or non-match) means for the user. That is, does a match mean they are granted full access to your network resources? Or does it mean they have limited access due to a non-compliance issue? For example, consider the following scenarios: • You create a HIP profile that matches if the required corporate antivirus and anti-spyware software packages are not installed. In this case, you might want to create a HIP notification message for users who match the HIP profile telling them that they need to install the software (and, optionally, providing a link to the file share where they can access the installer for the corresponding software). • You create a HIP profile that matches if those same applications are installed, you might want to create the message for users who do not match the profile, and direct them to the location of the install package. See Configure HIP-Based Policy Enforcement on page 177 for details on how to create HIP objects and HIP profiles and use in defining HIP notification messages. How Do I Get Visibility into the State of the End Clients? Whenever an end host connects to GlobalProtect, the agent presents its HIP data to the gateway. The gateway then uses this data to determine which HIP objects and/or HIP profiles the host matches. For each match, it generates a HIP Match log entry. Unlike a traffic log—which only creates a log entry if there is a policy match—the HIP Match log generates an entry whenever the raw data submitted by an agent matches a HIP object and/or a HIP profile you have defined. This makes the HIP Match log a good resource for monitoring the state of the hosts on your network over time—before attaching your HIP profiles to security policies—in order to help you determine exactly what policies you believe need enforcement. Because a HIP Match log is only generated when the host state matches a HIP object you have created, for full visibility in to host state you may need to create multiple HIP objects to log HIP matches for hosts that are in compliance with a particular state (for security policy enforcement purposes) as well as hosts that are non-compliant (for visibility). For example, suppose you want to prevent a host that does not have Antivirus software installed from connecting to the network. In this case you would create a HIP object that matches hosts that have a particular Antivirus software installed. By including this object in a HIP profile and attaching it to the security policy rule that allows access from your VPN zone, you can ensure that only hosts that are protected with antivirus software can connect. However, in this case you would not be able to see in the HIP Match log which particular hosts are not in compliance with this requirement. If you wanted to also see a log for hosts that do not have Antivirus software installed so that you can follow up with the users, you can also create a HIP object that matches the condition where the Antivirus software is not installed. Because this object is only needed for logging purposes, you do not need to add it to a HIP profile or attach it to a security policy rule. 176 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. Configure HIP-Based Policy Enforcement To enable the use of host information in policy enforcement you must complete the following steps. For more information on the HIP feature, see About Host Information. STEP 1 | Verify proper licensing for HIP checks. To use the HIP feature, you must have purchased and installed a GlobalProtect subscription license on each gateway that will perform HIP checks. To verify the status of your licenses on each portal and gateway, select Device > Licenses. Contact your Palo Alto Networks Sales Engineer or Reseller if you do not have the required licenses. For more information on licensing, see About GlobalProtect Licenses. STEP 2 | (Optional) Define any custom host information that you want the agent to collect. For example, if you have any required applications that are not included in the Vendor and/or Product lists for creating HIP objects, you could create a custom check that will allow you to determine whether that application is installed (has a corresponding registry or plist key) or is running (has a corresponding running process). 2 and 3 assume that you have already created a Portal Configuration. If you have not yet configured your portal, see Set Up Access to the GlobalProtect Portal for instructions. 1. On the firewall that is hosting your GlobalProtect portal, select Network > GlobalProtect > Portals. 2. Select your portal configuration to open the GlobalProtect Portal dialog. 3. Select the Agent tab and then select the agent configuration to which you want to add a custom HIP check, or click Add to create a new agent configuration. 4. Select the Data Collection tab. 5. Enable the option to Collect HIP Data. 6. Select Custom Checks and define the data you want to collect from hosts running this agent configuration as follows: GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 177 2017 Palo Alto Networks, Inc. • To collect information about specific registry keys: On the Windows tab, Add the name of a Registry Key for which to collect data in the Registry Key area. Optionally, to restrict data collection to a specific Registry Value, Add and then define the specific Registry Value or values. Click OK to save the settings. • To collect information about running processes: Select the appropriate tab (Windows or Mac) and then Add a process to the Process List. Enter the name of the process that you want the agent to collect information about. • To collect information about specific property lists: On the Mac tab, click Add in the Plist section. Enter the Plist for which to collect data. Optionally, click Add to restrict the data collection to specific Key values. Click OK to save the settings. 7. If this is a new client configuration, complete the rest of the configuration as desired. For instructions, see Define the GlobalProtect Agent Configurations. 8. Click OK to save the client configuration. 9. Commit the changes. STEP 3 | (Optional) Exclude categories from collection. 1. On the firewall that is hosting your GlobalProtect portal, select Network > GlobalProtect > Portals. 2. Select your portal configuration to open the GlobalProtect Portal dialog. 3. On the Agent tab, select the Agent configuration from which to exclude categories, or Add a new one. 4. Select Data Collection, and then verify that Collect HIP Data is enabled. 5. On the Exclude Categories tab, click Add. The Edit Exclude Category dialog displays. 6. Select the Category you want to exclude from the drop-down list. 7. (Optional) If you want to exclude specific vendors and/or products from collection within the selected category rather than excluding the entire category, click Add. You can then select the Vendor to exclude from the drop-down on the Edit Vendor dialog and, optionally, click Add to exclude specific products from that vendor. When you are done defining that vendor, click OK. You can add multiple vendors and products to the exclude list. 8. Repeat Step f and Step g for each category you want to exclude. 9. If this is a new client configuration, complete the rest of the configuration as desired. For more information on defining client configurations, see Define the GlobalProtect Agent Configurations. 10.Click OK to save the client configuration. 11.Commit the changes. STEP 4 | Create the HIP objects to filter the raw host data collected by the agents. The best way to determine what HIP objects you need is to determine how you will use the host information you collect to enforce policy. Keep in mind that the HIP objects themselves are merely building blocks that allow you to create the HIP profiles that are used in your security policies. Therefore, you may want to keep your objects simple, matching on one thing, such as the presence of a particular type of required software, membership in a specific domain, or the presence of a specific client OS. By doing this, you will have the flexibility to create a very granular (and very powerful) HIPaugmented policy. For details on a specific HIP category or field, refer to the online help. 1. On the gateway (or on Panorama if you plan to share the HIP objects among multiple gateways), select Objects > GlobalProtect > HIP Objects and click Add. 2. On the General tab, enter a Name for the object. 3. Select the tab that corresponds to the category of host information you are interested in matching against and select the check box to enable the object to match against the category. For example, 178 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. to create an object that looks for information about Antivirus software, select the Antivirus tab and then select the Antivirus check box to enable the corresponding fields. Complete the fields to define the desired matching criteria. For example, the following screenshot shows how to create an object that will match if the Symantec Norton AntiVirus 2004 Professional application is installed, has Real Time Protection enabled, and has virus definitions that have been updated within the last 5 days. Repeat this step for each category you want to match against in this object. For more information, see Table: Data Collection Categories. 4. Click OK to save the HIP object. 5. Repeat these steps to create each additional HIP object you require. 6. Commit the changes. STEP 5 | Create the HIP profiles that you plan to use in your policies. When you create your HIP profiles, you can combine the HIP objects you previously created (as well as other HIP profiles) using Boolean logic such that when a traffic flow is evaluated against the resulting HIP profile it will either match or not match. If there is a match, the corresponding policy rule will be enforced; if there is not a match, the flow will be evaluated against the next rule, as with any other policy matching criteria. 1. On the gateway (or on Panorama if you plan to share the HIP profiles among multiple gateways), select Objects > GlobalProtect > HIP Profiles and click Add. 2. Enter a descriptive Name for the profile and optionally a Description. 3. Click Add Match Criteria to open the HIP Objects/Profiles Builder. 4. Select the first HIP object or profile you want to use as match criteria and then click add to move it over to the Match text box on the HIP Profile dialog. Keep in mind that if you want the HIP profile to evaluate the object as a match only when the criteria in the object is not true for a flow, select the NOT check box before adding the object. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 179 2017 Palo Alto Networks, Inc. 5. Continue adding match criteria as appropriate for the profile you are building, making sure to select the appropriate Boolean operator radio button (AND or OR) between each addition (and, again, using the NOT check box when appropriate). 6. If you are creating a complex Boolean expression, you must manually add the parenthesis in the proper places in the Match text box to ensure that the HIP profile is evaluated using the logic you intend. For example, the following HIP profile will match traffic from a host that has either FileVault disk encryption (for Mac OS systems) or TrueCrypt disk encryption (for Windows systems) and also belongs to the required Domain, and has a Symantec antivirus client installed: 7. When you are done adding match criteria, click OK to save the profile. 8. Repeat these steps to create each additional HIP profile you require. 9. Commit the changes. STEP 6 | Verify that the HIP objects and HIP profiles you created are matching your GlobalProtect client traffic as expected. Consider monitoring HIP objects and profiles as a means to monitor the security state and activity of your host endpoints. By monitoring the host information over time you will be better able to understand where your security and compliance issues are and you can use this information to guide you in creating useful policy. For more details, see How Do I Get Visibility into the State of the End Clients? On the gateway(s) that your GlobalProtect users are connecting to, select Monitor > Logs > HIP Match. This log shows all of the matches the gateway identified when evaluating the raw HIP data reported by the agents against the defined HIP objects and HIP profiles. Unlike other logs, a HIP match does not require a security policy match in order to be logged. 180 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. STEP 7 | Enable User-ID on the source zones that contain the GlobalProtect users that will be sending requests that require HIP-based access controls. You must enable User-ID even if you don’t plan on using the user identification feature or the firewall will not generate any HIP Match logs entries. 1. Select Network > Zones. 2. Click on the Name of the zone in which you want to enable User-ID to open the Zone dialog. 3. Enable User ID by selecting the Enabled check box and then click OK. STEP 8 | Create the HIP-enabled security rules on your gateway(s). As a best practice, you should create your security rules and test that they match the expected flows based on the source and destination criteria as expected before adding your HIP profiles. By doing this you will also be better able to determine the proper placement of the HIP-enabled rules within the policy. 1. Select Policies > Security and select the rule to which you want to add a HIP profile. 2. On the Source tab, make sure the Source Zone is a zone for which you enabled User-ID in 7. 3. On the User tab, click Add in the HIP Profiles section and select the HIP profile(s) you want to add to the rule (you can add up to 63 HIP profiles to a rule). 4. Click OK to save the rule. 5. Commit the changes. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 181 2017 Palo Alto Networks, Inc. STEP 9 | Define the notification messages end users will see when a security rule with a HIP profile is enforced. The decision as to when to display a message (that is, whether to display it when the user’s configuration matches a HIP profile in the policy or when it doesn’t match it), depends largely on your policy and what a HIP match (or non-match) means for the user. That is, does a match mean they are granted full access to your network resources? Or does it mean they have limited access due to a non-compliance issue? For example, suppose you create a HIP profile that matches if the required corporate antivirus and antispyware software packages are not installed. In this case, you might want to create a HIP notification message for users who match the HIP profile telling them that they need to install the software. Alternatively, if your HIP profile matched if those same applications are installed, you might want to create the message for users who do not match the profile. 1. On the firewall that is hosting your GlobalProtect gateway(s), select Network > GlobalProtect > Gateways. 2. Select a previously-defined gateway configuration to open the GlobalProtect Gateway dialog. 3. Select Client Configuration > HIP Notification and then click Add. 4. Select the HIP Profile this message applies to from the drop-down. 5. Select Match Message or Not Match Message, depending on whether you want to display the message when the corresponding HIP profile is matched in policy or when it is not matched. In some cases you might want to create messages for both a match and a non-match, depending on what objects you are matching on and what your objectives are for the policy. For the Match Message, you can also enable the option to Include matched application list in message to indicate what applications triggered the HIP match. 6. Select the Enable check box and select whether you want to display the message as a Pop Up Message or as a System Tray Balloon. 7. Enter the text of your message in the Template text box and then click OK. The text box provides both a WYSIWYG view of the text and an HTML source view, which you can toggle between using the Source Edit icon. The toolbar also provides many options for formatting your text and for creating hyperlinks to external documents, for example to link users directly to the download URL for a required software program. 8. Repeat this procedure for each message you want to define. 9. Commit the changes. 182 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. STEP 10 | Verify that your HIP profiles are working as expected. You can monitor what traffic is hitting your HIP-enabled policies using the Traffic log as follows: 1. From the gateway, select Monitor > Logs > Traffic. 2. Filter the log to display only traffic that matches the rule that has the HIP profile you are interested in monitoring attached. For example, to search for traffic that matches a security rule named “iOS Apps” you would enter ( rule eq 'iOS Apps' ) in the filter text box as follows: GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 183 2017 Palo Alto Networks, Inc. Collect Application and Process Data From Clients The Windows Registry and Mac Plist can be used to configure and store settings and options for Windows and Mac operating systems, respectively. You can create a custom check that will allow you to determine whether an application is installed (has a corresponding registry or plist key) or is running (has a corresponding running process) on a Windows or Mac client. Enabling custom checks instructs the GlobalProtect agent to collect specific registry information (Registry Keys and Registry Key Values from Windows clients), preference list (plist) information (plist and plist keys from Mac OS clients). The data that you define to be collected in a custom check is included in the raw host information data collected by the GlobalProtect agent and then submitted to the GlobalProtect gateway when the agent connects. To monitor the data collected with custom checks you can create a HIP object. You can then add the HIP object to a HIP profile to use the collected data to match to device traffic and enforce security rules. The gateway can use the HIP object (which matches to the data defined in the custom check) to filter the raw host information submitted by the agent. When the gateway matches the client data to a HIP object, a HIP Match log entry is generated for the data. A HIP profile allows the gateway to also match the collected data to a security rule. If the HIP profile is used as criteria for a security policy rule, the gateway will enforce that security rule on the matching traffic. Use the following task to enable custom checks to collect data from Windows and Mac clients. This task includes the optional steps to create a HIP object and HIP profile for a custom check, if you would like to use client data as matching criteria for a security policy to monitor, identify, and act on traffic. For more information on defining agent settings directly from the Windows registry or the global Mac plist, see Deploy Agent Settings Transparently. STEP 1 | Enable the GlobalProtect agent to collect Windows Registry information from Windows clients or Plist information from Mac clients. The type of information collected can include whether or not an application is installed on the client, or specific attributes or properties of that application. This step enables the agent to report data on the applications and client settings. (5 and 6 will show you how to monitor and use the reported data to identify or take action on certain device traffic). Collect data from a Windows client: 1. Select Network > GlobalProtect > Portals and then select the portal configuration you want to modify or Add a new one. 2. Select the Agent tab and then select the Agent configuration you want to modify or Add a new one. 3. Select Data Collection, and then verify that Collect HIP Data is enabled. 4. Select Custom Checks > Windows. 5. Add the Registry Key that you want to collect information about. If you want to restrict data collection to a value contained within that Registry Key, add the corresponding Registry Value. 184 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. Collect data from a Mac client: 1. Select Network > GlobalProtect > Portals and then select the portal configuration you want to modify or Add a new one. 2. Select the Agent tab and then select the Agent configuration you want to modify or Add a new one. 3. Select Data Collection, and then verify that Collect HIP Data is enabled. 4. Select Custom Checks > Mac. 5. Add the Plist that you want to collect information about and the corresponding Plist Key to determine if the application is installed: For example, Add the Plist com.apple.screensaver and the Key askForPassword to collect information on whether a password is required to wake the Mac client after the screen saver begins: GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 185 2017 Palo Alto Networks, Inc. Confirm that the Plist and Key are added to the Mac custom checks: STEP 2 | (Optional) Check if a specific process is running on the client. 1.

Add the name of the process that you want to collect information about to the Process List. STEP 3 | Save the custom check. Click OK and Commit the changes. STEP 4 | Verify that the GlobalProtect agent is collecting the data defined in the custom check from the client. For Windows clients: On the Windows client, double-click the GlobalProtect icon on the task bar and click the Host State tab to view the information that the GlobalProtect agent is collecting from the Mac client. Under the custom-checks dropdown, verify that the data that you defined for collection in 7 is displayed: For Mac clients: 186 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. On the Mac client, click the GlobalProtect icon on the Menu bar, click Advanced View, and click Host State to view the information that the GlobalProtect agent is collecting for the Mac client. Under the custom-checks dropdown, verify that the data you defined for collection in 7 is displayed: STEP 5 | (Optional) Create a HIP Object to match to a Registry Key (Windows) or Plist (Mac). This can allow you to filter the raw host information collected from the GlobalProtect agent in order to monitor the data for the custom check. With a HIP object defined for the custom check data, the gateway will match the raw data submitted from the agent to the HIP object and a HIP Match log entry is generated for the data (Monitor > HIP Match). For Windows and Mac clients: 1. Select Objects > GlobalProtect > HIP Objects and Add a HIP Object. 2. Select and enable Custom Checks. For Windows clients only: 1. To check Windows clients for a specific registry key, select Registry Key and Add the registry to match on. To only identify clients that do not have the specified registry key, select Key does not exist or match the specified value data. 2. To match on specific values within the Registry key, click Add and then enter the registry value and value data. To identify clients that explicitly do not have the specified value or value data, select the Negate check box. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 187 2017 Palo Alto Networks, Inc. 3. Click OK to save the HIP object. You can Commit to view the data in the HIP Match logs at the next device check-in or continue to 6. For Mac clients only: 1. Select the Plist tab and Add and enter the name of the Plist for which you want to check Mac clients. (If instead, you want to match Mac clients that do not have the specified Plist, continue by selecting Plist does not exist). 2. (Optional) You can match traffic to a specific key-value pair within the Plist by entering the Key and the corresponding Value to match. (Alternatively, if you want to identify clients that do not have a specific Key and Value, you can continue by selecting Negate after adding populating the Key and Value fields). 3. Click OK to save the HIP object. You can Commit to view the data in the HIP Match logs at the next device check-in or continue to 6. STEP 6 | (Optional) Create a HIP profile to allow the HIP object you created in 5 to be evaluated against traffic. The HIP profile can be added to a security policy as an additional check for traffic matching that policy. When the traffic is matched to the HIP profile, the security policy rule will be enforced on the traffic. 188 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. For more details on creating a HIP profiles, see Configure HIP-Based Policy Enforcement. 1. Select Objects > GlobalProtect > HIP Profile. 2. Click Add Match Criteria to open the HIP Objects/Profiles Builder. 3. Select the HIP object you want to use as match criteria and then move it over to the Match box on the HIP Profile dialog. 4. When you have finished adding the objects to the new HIP profile, click OK and Commit. STEP 7 | Add the HIP profile to a security policy so that the data collected with the custom check can be used to match to and act on traffic. Select Policies > Security, and Add or modify a security policy. Go to the User tab to add a HIP profile to the policy. For more details on security policies components and using security policies to match to and act on traffic, see Security Policy. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 189 2017 Palo Alto Networks, Inc. Block Device Access In the event that a user loses a device that provides GlobalProtect access to your network, that device is stolen, or a user leaves your organization, you can block the device from gaining access to the network by placing the device in a block list. A block list is local to a logical network location (vsys, 1 for example) and can contain a maximum of 1,000 devices per location. Therefore, you can create separate device block lists for each location hosting a GlobalProtect deployments. STEP 1 | Identify the host ID for the endpoints you want to block. The host ID is a unique ID that GlobalProtect assigns to identify the host. The host ID value varies by device type: • Windows—Machine GUID stored in the Windows registry (HKEY_Local_Machine\Software \Microsoft\Cryptography\MachineGuid) • macOS—MAC address of the first built-in physical network interface • Android—Android ID • iOS—UDID • Chrome—GlobalProtect assigned unique alphanumeric string with length of 32 characters If you do not know the host ID, you can correlate the user-ID to the host ID in the HIP Match logs: 1. Select Monitor > Logs > HIP Match. 2. Filter the HIP match logs for the source user associated with the device. 3. Open the HIP match log and identify the host ID under OS > Host ID and optionally the hostname under Host Information > Machine Name. STEP 2 | Create a device block list. 190 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. You cannot use Panorama templates to push a device block list to firewalls. 1. Select Network > GlobalProtect > Device Block List and Add a device block list. 2. Enter a descriptive Name for the list. 3. For a firewall with more than one virtual system (vsys), select the Location (vsys or Shared) where the profile is available. STEP 3 | Add a device to a block list. 1. Add devices. Enter the host ID (required) and hostname (optional) for a device you need to block. 2. Add additional devices, if needed. 3. Click OK to save and activate the block list. The device list does not require a commit and is immediately active. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 191 2017 Palo Alto Networks, Inc. Configure Windows User-ID Agent to Collect Host Information The Windows-based User-ID agent has been extended to support a new AirWatch MDM integration service. This service enables GlobalProtect to use the host information collected by the service to enforce HIP-based policies on devices managed by AirWatch. Running as part of the Windows-based User-ID agent, the AirWatch MDM integration service uses the AirWatch API to collect information from mobile devices that are managed by VMware AirWatch and translate this data into host information. For Android devices managed by AirWatch, this feature supports Android for Work devices, but it does not support other types of Android devices. • • • • • MDM Integration Overview on page 192 Information Collected on page 192 System Requirements on page 194 Configure GlobalProtect to Retrieve Host Information on page 194 Troubleshoot the MDM Integration Service on page 197 MDM Integration Overview MDM integration service included with the Windows-based User-ID agent does a full HIP query to the AirWatch MDM server to get the complete host information for a device. GlobalProtect apps on the devices also send HIP information to the gateway and the gateway merges HIP information from the GlobalProtect apps and the MDM integration service. When a mobile device running the GlobalProtect app is connected to a GlobalProtect gateway, GlobalProtect can apply security policies with host information profiles. You configure the MDM integration service to fetch AirWatch device information at regular intervals and push this information to GlobalProtect gateways. In addition, the service can monitor AirWatch event notifications and fetch updated device information when AirWatch events occur (for example, device enrollment, device wipe, and compliance changes). Information Collected The following table shows how information collected from devices managed by AirWatch are translated into HIP report attributes. The mapping is done automatically. 192 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc.

STEP 1 | Install and configure the Windows-based User-ID agent. The User-ID agent must be in a location that enables secure connections to the VMware AirWatch Mobile Device Management (MDM) system. For more information, see Install the User-ID Agent. The AirWatch MDM integration service is included with the PAN-OS Windows-based User-ID agent. STEP 2 | Configure SSL authentication between the Windows-based User-ID agent and the GlobalProtect gateway. 194 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. When you configure SSL authentication, make sure: • The server certificate configured on the Windows-based User-ID Agent has the same Common Name (CN) as the hostname/IP address of the User-ID Agent host. • The server certificate is trusted by the firewall (included in the trusted CA list in the MDM configuration on the firewall). • The root certificate authority (CA) certificate of the MDM client certificate configured on the firewall must be imported into Windows trust store of the Windows server. 1. Obtain a server certificate and private key for authentication between the Windows-based User-ID agent and the GlobalProtect gateway. The certificate bundle must be in PEM format that contains a PEM certificate, full certificate chain, and private key. 2. Open the Windows-based User-ID agent and select Server Certificate. 3. Add the server certificate. • Browse to the certificate file and Open the file to upload the certificate to the Windows-based UserID agent. • Enter a Private Key Password for the certificate. • Click OK. The agent verifies the certificate is valid and stores the encryption password of the private key in the host machine’s Windows credential store. If installation is successful, detailed information about the certificate (including common name, expiration date, and issuer) appears on the Server Certificate tab. 1. Restart the Windows-based User-ID agent. STEP 3 | Configure the MDM integration service on the Windows-based User-ID agent. 1. Select MDM Integration in the Windows-based User-ID agent. 2. In Gateway Connection TCP Port, specify a port for TCP communications. The Windows-based UserID agent listens at this port for all MDM-related messages. The default port is 5008. To change the port, specify a number from 1 to 65535. 3. On the Setup tab, click Edit. 4. Choose AirWatch for the MDM Vendor. STEP 4 | Specify the MDM Event Notification settings to monitor and collect AirWatch events (for example, device enrollment, device wipe, and compliance changes). When an event occurs, the MDM integration service fetches the updated device information from the AirWatch API and pushes this information to all configured GlobalProtect gateways. For MDM Event Notification, make sure the values you enter here are also configured in the AirWatch console under Groups & Settings > All Settings > System > Advanced > API > Event Notifications.

For example, api.awmdm.com. • Enter the Username and Password credentials needed to access the AirWatch MDM API. • Enter the Tenant Code.This is a unique hexadecimal code number required to access the AirWatch MDM API. On the AirWatch console, you can find the tenant code at System > Advanced > API > REST API > API Key. • Enter the Mobile Device State Retrieval Interval. This setting controls how often host information is retrieved from devices managed by AirWatch. The default is 30 minutes. To change the interval, specify a number from 1 to 600. STEP 6 | Commit your changes. 196 GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 2017 Palo Alto Networks, Inc. STEP 7 | Click Test Connection to make sure the Windows-based User-ID agent can connect to the AirWatch API. STEP 8 | Configure the GlobalProtect gateway to communicate with the MDM integration service to retrieve the HIP reports for the devices managed by AirWatch. 1. In the PAN-OS web interface, select Network > GlobalProtect > MDM. 2. Add the following information about the MDM integration service. • Name—Enter a name for the MDM integration service (up to 31 characters). The name is casesensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores. • (Optional) Select the virtual system to which the gateway belongs. • Server—Enter the IP address or FQDN of the interface on the Airwatch MDM integration service where the gateway connects to retrieve HIP reports. Ensure that you have a service route to this interface. • Connection Port—Enter the connection port where the MDM integration service listens for HIP report requests. The default port is 5008. To change the port, specify a number from 1 to 65535. • Client Certificate—Choose the client certificate for the gateway to present to the MDM integration service when it establishes an HTTPS connection. You can choose a client certificate from the drop down, or import a new client certificate. The Certificate Purpose must indicate that it is a client authentication certificate. The root certificate authority (CA) certificate of the client certificate must be imported into the Windows trust store of the Windows server where the User-ID Agent is installed. 1. Add the root CA certificate associated with the server certificate installed on the MDM integration service host. You need both the root CA certificate and the server certificate to establish a secure connection between the gateway and the MDM integration service. You can choose a root CA certificate from the drop down, or Import a new certificate. 2. Click OK. 3. Commit your changes. STEP 9 | Check your connection to make sure AirWatch device data is transferred to GlobalProtect. 1. Open the Windows-based User-ID agent and select MDM Integration > Mobile Devices. You should see a list of unique device IDs and user names for all the devices managed by AirWatch. 2. (Optional) You can Filter the list to find a specific Mobile Device. 3. (Optional). Select a device in the list of device IDs and click Retrieve Device State to extract the latest information about the device and see how it maps to host information profiles on the GlobalProtect gateway. Troubleshoot the MDM Integration Service Follow these instructions if you have trouble with event notifications or trouble authenticating to the AirWatch REST API. • Event notifications from the AirWatch MDM server are not received by the MDM integration service. 1. Set the Debug option (in the File menu) to Debug or Verbose. 2. Go the User-ID agent installation folder on the Windows server and open the MaDebug file. Look for messages similar to the following: The address x.x.x.x is not in the permitted ip list for event notifications. GLOBALPROTECT ADMINISTRATOR'S GUIDE | Host Information © 197 2017 Palo Alto Networks, Inc. 3. Add this IP address as a Permitted IP address (MDM Integration > Setup > Permitted IP). • Authentication to the Airwatch REST API is unsuccessful. Make sure that: • The credentials used for the MDM integration service to authenticate to the AirWatch MDM service are valid. • The user account used to access the Airwatch REST API has API access permissions and read-only permissions (at minimum) to data for the mobile devices and users managed by AirWatch. • The Tenant Code (API key) is correctly associated with the user account.

Remote Access VPN (Authentication Profile) In the GlobalProtect VPN for Remote Access, the GlobalProtect portal and gateway are configured on ethernet1/2, so this is the physical interface where GlobalProtect clients connect. After a client connects and the portal and gateway authenticates it, the client establishes a VPN tunnel from its virtual adapter, which has been assigned an address in the IP address pool associated with the gateway tunnel.2 configuration—10.31.32.3-10.31.32.118 in this example. Because GlobalProtect VPN tunnels terminate in a separate corp-vpn zone, you have visibility into the VPN traffic as well as the ability to customize security policy for remote users. Watch the video. Figure 3: GlobalProtect VPN for Remote Access The following procedure provides the configuration steps for this example. You can also watch the video. STEP 1 | Create Interfaces and Zones for GlobalProtect. Use the default virtual router for all interface configurations to avoid having to create interzone routing. • Select Network > Interfaces > Ethernet and configure ethernet1/2 as a Layer 3 Ethernet interface with IP address 203.0.113.1 and assign it to the l3-untrust zone and the default virtual router. • Create a DNS “A” record that maps IP address 203.0.113.1 to gp.acme.com. • Select Network > Interfaces > Tunnel and add the tunnel.2 interface and add it to a new zone called corp-vpn. Assign it to the default virtual router. • Enable User Identification on the corp-vpn zone. STEP 2 | Create security policy to enable traffic flow between the corp-vpn zone and the l3-trust zone to enable access to your internal resources. 1. Select Policies > Security and then Add a new rule. 2. For this example, you would define the rule with the following settings: • Name—VPN Access • Source Zone—corp-vpn • Destination Zone—l3-trust GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 201 2017 Palo Alto Networks, Inc. STEP 3 | Obtain a server certificate for the interface hosting the GlobalProtect portal and gateway using one of the following methods: • (Recommended) Import a server certificate from a well-known, third-party CA. • Use the root CA on the portal to generate a self-signed server certificate. Select Device > Certificate Management > Certificates to manage certificates as follows: • Obtain a server certificate. Because the portal and gateway are on the same interface, the same server certificate can be used for both components. • The CN of the certificate must match the FQDN, gp.acme.com. • To enable clients to connect to the portal without receiving certificate errors, use a server certificate from a public CA. STEP 4 | Create a server profile. The server profile instructs the firewall how to connect to the authentication service. Supported methods are Local, RADIUS, Kerberos, SAML, and LDAP authentication. This example shows an LDAP authentication profile for authenticating users against the Active Directory. Create the server profile for connecting to the LDAP server (Device > Server Profiles > LDAP). STEP 5 | (Optional) Create an authentication profile. Attach the server profile to an authentication profile (Device > Authentication Profile). 202 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. STEP 6 | Configure a GlobalProtect Gateway. Select Network > GlobalProtect > Gateways and add the following configuration: Interface—ethernet1/2 IP Address—203.0.113.1 Server Certificate—GP-server-cert.pem issued by GoDaddy Authentication Profile—Corp-LDAP Tunnel Interface—tunnel.2 IP Pool—10.31.32.3 - 10.31.32.118 STEP 7 | Configure the GlobalProtect Portals. Select Network > GlobalProtect > Portals and add the following configuration: 1. Set Up Access to the GlobalProtect Portal. This example uses the following settings: Interface—ethernet1/2 IP Address—203.0.113.1 Server Certificate—GP-server-cert.pem issued by GoDaddy Authentication Profile—Corp-LDAP 2. Define the GlobalProtect Client Authentication Configurations using the following settings: Connect Method—On-demand (Manual user initiated connection) External Gateway Address—gp.acme.com STEP 8 | Deploy the GlobalProtect Agent Software. Select Device > GlobalProtect Client. In this example, use the procedure to Host Agent Updates on the Portal. STEP 9 | (Optional) Enable use of the GlobalProtect mobile app. Purchase and install a GlobalProtect subscription (Device > Licenses) to enable use of the app. STEP 10 | Save the GlobalProtect configuration. Click Commit. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 203 2017 Palo Alto Networks, Inc. Remote Access VPN (Certificate Profile) With certificate authentication, the client must present a valid client certificate that identifies the user to the GlobalProtect portal or gateway. In addition to the certificate itself, the portal or gateway can use a certificate profile to determine whether the client that sent the certificate is the client to which the certificate was issued. When a client certificate is the only means of authentication, the certificate that the client presents must contain the username in one of the certificate fields; typically the username corresponds to the common name (CN) in the Subject field of the certificate. Upon successful authentication, the GlobalProtect agent establishes a VPN tunnel with the gateway and is assigned an IP address from the IP pool in the gateway’s tunnel configuration. To support user-based policy enforcement on sessions from the corp-vpn zone, the username from the certificate is mapped to the IP address that the gateway assigned. Also, if a security policy requires a domain name in addition to user name, the specified domain value in the certificate profile is appended to the username. Figure 4: GlobalProtect Client Certificate Authentication Configuration This quick configuration uses the same topology as GlobalProtect VPN for Remote Access. The only configuration difference is that instead of authenticating users against an external authentication server, this configuration uses client certificate authentication only. STEP 1 | Create Interfaces and Zones for GlobalProtect. Use the default virtual router for all interface configurations to avoid having to create interzone routing. • Select Network > Interfaces > Ethernet and configure ethernet1/2 as a Layer 3 Ethernet interface with IP address 203.0.113.1 and assign it to the l3-untrust security zone and the default virtual router. • Create a DNS “A” record that maps IP address 203.0.113.1 to gp.acme.com. • Select Network > Interfaces > Tunnel. • Add tunnel.2 interface to a new zone called corp-vpn. Assign the interface to the default virtual router. • Enable User Identification on the corp-vpn zone. 204 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. STEP 2 | Create security policy to enable traffic flow between the corp-vpn zone and the l3-trust zone to enable access to your internal resources. 1. Select Policies > Security and then Add a new rule. 2. For this example, you would define the rule with the following settings: • Name—VPN Access • Source Zone—corp-vpn • Destination Zone—l3-trust STEP 3 | Obtain a server certificate for the interface hosting the GlobalProtect portal and gateway using one of the following methods: • (Recommended) Import a server certificate from a well-known, third-party CA. • Use the root CA on the portal to generate a self-signed server certificate. Select Device > Certificate Management > Certificates to manage certificates as follows: • Obtain a server certificate. Because the portal and gateway are on the same interface, the same server certificate can be used for both components. • The CN of the certificate must match the FQDN, gp.acme.com. • To enable clients to connect to the portal without receiving certificate errors, use a server certificate from a public CA. STEP 4 | Issue client certificates to GlobalProtect clients and endpoints. 1. Use your enterprise PKI or a public CA to issue a unique client certificate to each GlobalProtect user. 2. Install certificates in the personal certificate store on the endpoints. STEP 5 | Create a client certificate profile. 1. Select Device > Certificate Management > Certificate Profile, click Add and enter a profile Name such as GP-client-cert. 2. Select Subject from the Username Field drop-down. 3. Click Add in the CA Certificates section, select the CA Certificate that issued the client certificates, and click OK twice. STEP 6 | Configure a GlobalProtect Gateway. See the topology diagram shown in GlobalProtect VPN for Remote Access. Select Network > GlobalProtect > Gateways and add the following configuration: Interface—ethernet1/2 IP Address—203.0.113.1 Server Certificate—GP-server-cert.pem issued by GoDaddy Certificate Profile—GP-client-cert Tunnel Interface—tunnel.2 IP Pool—10.31.32.3 - 10.31.32.118 STEP 7 | Configure the GlobalProtect Portals. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 205 2017 Palo Alto Networks, Inc. Select Network > GlobalProtect > Portals and add the following configuration: 1. Set Up Access to the GlobalProtect Portal: Interface—ethernet1/2 IP Address—203.0.113.1 Server Certificate—GP-server-cert.pem issued by GoDaddy Certificate Profile—GP-client-cert 2. Define the GlobalProtect Agent Configurations: Connect Method—On-demand (Manual user initiated connection) External Gateway Address—gp.acme.com STEP 8 | Deploy the GlobalProtect Agent Software.

STEP 9 | (Optional) Enable use of the GlobalProtect mobile app. Purchase and install a GlobalProtect subscription (Device > Licenses) to enable use of the app. STEP 10 | Save the GlobalProtect configuration. Click Commit. 206 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. Remote Access VPN with Two-Factor Authentication If you configure a GlobalProtect portal or gateway with an authentication profile and a certificate profile (which together can provide two-factor authentication), the end user must succeed at authentication through both profiles before gaining access. For portal authentication, this means that certificates must be pre-deployed to the end clients before their initial portal connection. Additionally, the client certificate presented by a client must match what is defined in the certificate profile. • If the certificate profile does not specify a username field (that is, the Username Field it is set to None), the client certificate does not need to have a username. In this case, the client must provide the username when authenticating against the authentication profile. • If the certificate profile specifies a username field, the certificate that the client presents must contain a username in the corresponding field. For example, if the certificate profile specifies that the username field is Subject, the certificate presented by the client must contain a value in the common-name field, or else the authentication fails. In addition, when the username field is required, the value from the username field of the certificate is automatically populated as the username when the user attempts to enter credentials for authenticating to the authentication profile. If you do not want force users to authenticate with a username from the certificate, do not specify a username field in the certificate profile. This quick configuration uses the same topology as GlobalProtect VPN for Remote Access. However, in this configuration the clients must authenticate against a certificate profile and an authentication profile. For more details on a specific type of two-factor authentication, see the following topics: • Enable Two-Factor Authentication Using Certificate and Authentication Profiles • Enable Two-Factor Authentication Using One-Time Passwords (OTPs) • Enable Two-Factor Authentication Using Smart Cards Use the following procedure to configure VPN Remote Access with Two-Factor Authentication. STEP 1 | Create Interfaces and Zones for GlobalProtect. Use the default virtual router for all interface configurations to avoid having to create interzone routing. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 207 2017 Palo Alto Networks, Inc. • Select Network > Interfaces > Ethernet and configure ethernet1/2 as a Layer 3 Ethernet interface with IP address 203.0.113.1 and assign it to the l3-untrust security zone and the default virtual router. • Create a DNS “A” record that maps IP address 203.0.113.1 to gp.acme.com. • Select Network > Interfaces > Tunnel and add the tunnel.2 interface and add it to a new zone called corp-vpn. Assign it to the default virtual router. • Enable User Identification on the corp-vpn zone. STEP 2 | Create security policy to enable traffic flow between the corp-vpn zone and the l3-trust zone to enable access to your internal resources. 1. Select Policies > Security and then click Add to add a new rule. 2. For this example, you would define the rule with the following settings: • Name—VPN Access • Source Zone—corp-vpn • Destination Zone—l3-trust STEP 3 | Obtain a server certificate for the interface hosting the GlobalProtect portal and gateway using one of the following methods: • (Recommended) Import a server certificate from a well-known, third-party CA. • Use the root CA on the portal to generate a self-signed server certificate. Select Device > Certificate Management > Certificates to manage certificates as follows: • Obtain a server certificate. Because the portal and gateway are on the same interface, the same server certificate can be used for both components. • The CN of the certificate must match the FQDN, gp.acme.com. • To enable clients to connect to the portal without receiving certificate errors, use a server certificate from a public CA. STEP 4 | Issue client certificates to GlobalProtect clients and endpoints. 1. Use your enterprise PKI or a public CA to issue a unique client certificate to each GlobalProtect user. 2. Install certificates in the personal certificate store on the endpoints. STEP 5 | Create a client certificate profile. 1. Select Device > Certificate Management > Certificate Profile, Add and enter a profile Name such as GP-client-cert. 2. Specify where to get the username that will be used to authenticate the end user: • From user—If you want the end user to supply a username when authenticating to the service specified in the authentication profile, select None as the Username Field. • From certificate—If you want to extract the username from the certificate, select Subject as the Username Field. If you use this option, the CN contained in the certificate will automatically populated the username field when the user is prompted to login to the portal/gateway and the user will be required to log in using that username. 3. In the CA Certificates section, Add and then select the CA Certificate that issued the client certificates, and click OK twice. 208 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. STEP 6 | Create a server profile. The server profile instructs the firewall how to connect to the authentication service. Local, RADIUS, Kerberos, SAML, and LDAP authentication methods are supported. This example shows an LDAP authentication profile for authenticating users against the Active Directory. Create the server profile for connecting to the LDAP server (Device > Server Profiles > LDAP). STEP 7 | (Optional) Create an authentication profile. Attach the server profile to an authentication profile (Device > Authentication Profile). STEP 8 | Configure a GlobalProtect Gateway. See the topology diagram shown in GlobalProtect VPN for Remote Access. Select Network > GlobalProtect > Gateways and add the following configuration: Interface—ethernet1/2 IP Address—203.0.113.1 Server Certificate—GP-server-cert.pem issued by GoDaddy Certificate Profile—GP-client-cert Authentication Profile—Corp-LDAP Tunnel Interface—tunnel.2 IP Pool—10.31.32.3 - 10.31.32.118 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 209 2017 Palo Alto Networks, Inc.

Select Device > GlobalProtect Client. In this example, use the procedure to Host Agent Updates on the Portal. STEP 11 | (Optional) Deploy Agent Settings Transparently. As an alternative to deploying agent settings from the portal configuration, you can define settings directly from the Windows registry or global MAC plist. Examples of settings that you can deploy include specifying the portal IP address or enabling GlobalProtect to initiate a VPN tunnel before a user logs in to the device and connects to the GlobalProtect portal. On Windows clients only, you can also configure settings using the MSIEXEC installer. For additional information, see Customizable Agent Settings. STEP 12 | (Optional) Enable use of the GlobalProtect mobile app. Purchase and install a GlobalProtect subscription (Device > Licenses) to enable use of the app. STEP 13 | Save the GlobalProtect configuration. Click Commit. 210 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. Always On VPN Configuration In an “always on” GlobalProtect configuration, the agent connects to the GlobalProtect portal upon user logon to submit user and host information and receive the client configuration. It then automatically establishes the VPN tunnel to the gateway specified in the client configuration delivered by the portal without end user intervention as shown in the following illustration. To switch any of the previous remote access VPN configurations to an always-on configuration, you simply change the connect method: • Remote Access VPN (Authentication Profile) on page 201 • Remote Access VPN (Certificate Profile) on page 204 • Remote Access VPN with Two-Factor Authentication on page 207 Use the following procedure to switch to an Always On configuration. STEP 1 | Select Network > GlobalProtect > Portals and select the portal configuration to open it. STEP 2 | Select the Agent tab and then select the agent configuration you want to modify. STEP 3 | Select the App tab. STEP 4 | Select User-logon (Always On) as the Connect Method. Repeat this step for each agent configuration. STEP 5 | Click OK twice to save the agent configuration and the portal configuration and then Commit your changes. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 211 2017 Palo Alto Networks, Inc. Remote Access VPN with Pre-Logon Pre-logon is a connect method that establishes a VPN tunnel before a user logs in. The purpose of prelogon is to authenticate the endpoint (not the user) and then enable domain scripts and other tasks of your choice to run as soon as the endpoint powers on. A machine certificate enables the endpoint to have the VPN tunnel to the gateway. A common practice for IT personnel is to install the machine certificate while staging the endpoint for the user. A pre-logon VPN tunnel has no username association because the user has not logged in. Therefore, to let the endpoint have access to resources in the trust zone, you must create security policies that match the pre-logon user. These policies should allow access to only the basic services for starting up the system, such as DHCP, DNS, Active Directory (for example, to change an expired password), antivirus, or operating system update services. After the gateway authenticates a Windows user, the VPN tunnel is reassigned to that user (the IP address mapping on the firewall changes from the pre-logon endpoint to the authenticated user). Mac systems behave differently from Windows systems with pre-logon. With Mac OS, the tunnel created for pre-logon is torn down and a new tunnel created when the user logs in. When a client requests a new connection, the portal authenticates the client by using an authentication profile. The portal can also use an optional certificate profile that validates the client certificate (if the configuration includes a client certificate). In this case, the client certificate must identify the user. After authentication, the portal determines if the client’s configuration is current. If the portal’s configuration for the agent has changed, it pushes an updated configuration to the endpoint. If the configuration on the portal or a gateway includes cookie-based authentication for the client, the portal or gateway installs an encrypted cookie on the client. Subsequently, the portal or gateway uses the cookie to authenticate users and for refreshing the client’s configuration. Also, if an agent configuration profile includes the pre-logon connect method in addition to cookie-authentication, the GlobalProtect components can use the cookie for pre-logon. If users never log into a device (for example, a headless device) or a pre-logon connection is required on a system that a user has not previously logged into, you can let the endpoint initiate a pre-logon tunnel without first connecting to the portal to download the pre-logon configuration. To do this, you must override the default behavior by creating entries in the Windows registry or Mac plist. The GlobalProtect endpoint will then connect to the portal specified in the configuration and authenticate the endpoint by using its machine certificate (as specified in a certificate profile configured on the gateway) and establish the VPN tunnel. When the end user subsequently logs in to the machine and if single sign-on (SSO) is enabled in the client configuration, the username and password are captured while the user logs in and used to authenticate to the gateway and so that the tunnel can be renamed (Windows). If SSO is not enabled in the client configuration or of SSO is not supported on the client system (for example, it is a Mac OS system) the users’ credentials must be stored in the agent (that is, the Save User Credentials option must be set to Yes). After successful authentication to the gateway the tunnel will be renamed (Windows) or rebuilt (Mac) and userand group-based policy can be enforced. 212 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. This example uses the GlobalProtect topology shown in GlobalProtect VPN for Remote Access. STEP 1 | Create Interfaces and Zones for GlobalProtect. Use the default virtual router for all interface configurations to avoid having to create interzone routing. • For this example, select Network > Interfaces > Ethernet and then: • Select ethernet1/2. • For its interface type, select Layer 3. • Assign interface to: default virtual router, default virtual system, and l3-untrust security zone. • Select IPv4 and Add. • Select the address 203.0.113.1 (or the object that maps 203.0.113.1) or add a New Address to create a new object and address mapping. (Leave the address type as Static.) • Create a DNS “A” record that maps IP address 203.0.113.1 to gp.acme.com. • Select Network > Interfaces > Tunnel. • Add a tunnel.2 interface to a new zone called corp-vpn. Assign it to the default virtual router. • Enable User Identification on the corp-vpn zone. STEP 2 | Create the security policy rules. This configuration requires the following policies (Policies > Security): 1. Create a rule that enables pre-logon user access to basic services that are required for the computer to come up, such as authentication services, DNS, DHCP, and Microsoft Updates. 2. Create a rule to deny pre-logon user access to all other destinations and applications. 3. Create any additional rules to enable access to specific destinations and applications for specific users or user groups. Follow the Best Practice Internet Gateway Security Policy recommendations for creating these rules. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 213 2017 Palo Alto Networks, Inc. STEP 3 | Use one of the following methods to obtain a server certificate for the interface that is hosts the GlobalProtect portal and gateway: • (Recommended) Import a server certificate from a well-known, third-party CA. • Use the root CA on the portal to generate a self-signed server certificate. Select Device > Certificate Management > Certificates to manage certificates with the following criteria: • Obtain a server certificate. Because the portal and gateway are on the same interface, the same server certificate can be used for both components. • The CN of the certificate must match the FQDN, gp.acme.com. • To enable clients to connect to the portal without receiving certificate errors, use a server certificate from a public CA. STEP 4 | Generate a machine certificate for each client system that will connect to GlobalProtect and import them into the personal certificate store on each machine. Although you could generate self-signed certificates for each client system, as a best practice, use your own public-key infrastructure (PKI) to issue and distribute certificates to your clients. 1. Issue client certificates to GlobalProtect clients and endpoints. 2. Install certificates in the personal certificate store on the endpoints. (Local Computer store on Windows or System Keychain on Mac OS) STEP 5 | Import the trusted root CA certificate from the CA that issued the machine certificates onto the portal and gateway(s). You do not have to import the private key. 1. Download the CA certificate in Base64 format. 2. Import the certificate onto each firewall that hosts a portal or gateway, as follows: 1. 2. 3. 4. 5. 6. Select Device > Certificate Management > Certificates > Device Certificates and click Import. Enter a Certificate Name that identifies the certificate as your client CA certificate. Browse to the Certificate File you downloaded from the CA. Select Base64 Encoded Certificate (PEM) as the File Format and then click OK. Select the certificate you just imported on the Device Certificates tab to open it. Select Trusted Root CA and then click OK. STEP 6 | On each firewall that hosts a GlobalProtect gateway, create a certificate profile to identify the CA certificate for validating the machine certificates. Optionally, if you plan to use client certificate authentication to authenticate users when they log in to the system, make sure that the CA certificate that issues the client certificates is referenced in the certificate profile in addition to the CA certificate that issued the machine certificates if they are different. Select Device > Certificates > Certificate Management > Certificate Profile. Click Add and enter a Name to uniquely identify the profile, such as PreLogonCert. Set Username Field to None. (Optional) If you will also use client certificate authentication to authenticate users upon login, add the CA certificate that issued the client certificates if it is different from the one that issued the machine certificates. 5. In the CA Certificates field, click Add, select the Trusted Root CA certificate you imported in 5 and then click OK. 1. 2. 3. 4. 214 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. 6. Click OK to save the profile. STEP 7 | Configure a GlobalProtect Gateway. See the topology diagram shown in GlobalProtect VPN for Remote Access. Although you must create a certificate profile for pre-logon access to the gateway, you can use either client certificate authentication or authentication profile-based authentication for logged in users. In this example, the same LDAP profile is used that is used to authenticate users to the portal. 1. Select Network > GlobalProtect > Gateways and add the following configuration: Interface—ethernet1/2 IP Address—203.0.113.1 Server Certificate—GP-server-cert.pem issued by GoDaddy Certificate Profile—PreLogonCert Authentication Profile—Corp-LDAP Tunnel Interface—tunnel.2 IP Pool—10.31.32.3 - 10.31.32.118 2. Commit the gateway configuration. STEP 8 | Configure the GlobalProtect Portals. Configure Device details (networking parameters, the authentication service profile, and the certificate for the authentication server). Select Network > GlobalProtect > Portals and specify the following configuration: Set Up Access to the GlobalProtect Portal: Interface—ethernet1/2 IP Address—203.0.113.1 Server Certificate—GP-server-cert.pem issued by GoDaddy Certificate Profile—None Authentication Profile—Corp-LDAP STEP 9 | Define the GlobalProtect Agent Configurations for pre-logon users and for logged in users. Use a single agent configuration if you want pre-logon users to access the same gateways before and after they log in. Otherwise, to direct pre-logon users to different gateways before and after they log in, create two agent configuration profiles. In this first agent configuration’s User/User Group, select the pre-logon filter. With pre-logon, the portal first authenticates the endpoint, not the user, to set up a VPN (even though the pre-logon parameter is associated with users). Subsequently, the portal authenticates the user when he or she logs in. After the portal authenticates the user, it deploys the second agent configuration. In this case, User/ User Group is any. As a best practice, enable SSO in the second agent configuration so that the correct username is immediately reported to the gateway when the user logs in to the endpoint. If SSO is not enabled, the saved username in the Agent settings panel is used. Select Agent and specify one of the following configurations: GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 215 2017 Palo Alto Networks, Inc. • Use the same gateway before and after pre-logon users log in: Use single sign-on—enabled Connect Method—pre-logon External Gateway Address—gp1.acme.com User/User Group—any Authentication Override—Cookie authentication for transparently authenticating users and for configuration refresh • Use separate gateways for pre-logon users before and after they log in: First Agent Configuration: Connect Method—pre-logon External Gateway Address—gp1.acme.com User/User Group—pre-logon Authentication Override—Cookie authentication for transparently authenticating users and for configuration refresh Second Agent Configuration: Use single sign-on—enabled Connect Method—pre-logon External Gateway Address—gp2.acme.com User/User Group—any Authentication Override—Cookie authentication for transparently authenticating users and for configuration refresh Make sure the pre-logon client configuration is first in the list of configurations. If it is not, select it and click Move Up. STEP 10 | Save the GlobalProtect configuration. Click Commit. STEP 11 | (Optional) If users will never log into a device (for example, a headless device) or a pre-logon connection is required on a system that a user has not previously logged into, create the Prelogon registry entry on the client system. You must also pre-deploy additional agent settings such as the default portal IP address and connect method. For more information about registry settings, see Deploy Agent Settings Transparently. 1. Locate the GlobalProtect settings in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Palo Alto Networks\GlobalProtect\PanSetup 2. Create a DWORD named Prelogon with a value of 1 in the Value data field and Hexadecimal as the Base. This setting enables GlobalProtect to initiate a VPN connection before the user logs into the laptop. 3. Create a String Value named Portal that specifies the IP address or hostname of the default portal for the GlobalProtect client. 216 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. 4. Create a String Value named connect-method with a value of pre-logon in the Value data field. This setting enables GlobalProtect to initiate a VPN tunnel before a user logs in to the device and connects to the GlobalProtect portal. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 217 2017 Palo Alto Networks, Inc. GlobalProtect Multiple Gateway Configuration In GlobalProtect Multiple Gateway Topology, a second external gateway has been added to the configuration. Multiple gateways are supported in all of the preceding example configurations. Additional steps include configuring a second firewall as a GlobalProtect gateway. In addition, when configuring the client configurations to be deployed by the portal you can decide whether to allow access to all gateways, or specify different gateways for different configurations. Figure 5: GlobalProtect Multiple Gateway Topology If a client configuration contains more than one gateway, the agent will attempt to connect to all gateways listed in its client configuration. The agent will then use priority and response time as to determine the gateway to which to connect. The agent connects to a lower priority gateway only if the response time for the higher priority gateway is greater than the average response time across all gateways. For more information, see Gateway Priority in a Multiple Gateway Configuration. STEP 1 | Create Interfaces and Zones for GlobalProtect. In this configuration, you must set up interfaces on each firewall hosting a gateway. Use the default virtual router for all interface configurations to avoid having to create interzone routing. On the firewall hosting the portal/gateway (gw1): • Select Network > Interfaces > Ethernet and configure ethernet1/2 as a Layer 3 Ethernet interface with IP address 198.51.100.42 and assign it to the l3-untrust security zone and the default virtual router. • Create a DNS “A” record that maps IP address 198.51.100.42 to gp1.acme.com. • Select Network > Interfaces > Tunnel and add the tunnel.2 interface and add it to a new zone called corp-vpn. Assign it to the default virtual router. • Enable User Identification on the corp-vpn zone. On the firewall hosting the second gateway (gw2): • Select Network > Interfaces > Ethernet and configure ethernet1/5 as a Layer 3 Ethernet interface with IP address 192.0.2.4 and assign it to the l3-untrust security zone and the default virtual router. • Create a DNS “A” record that maps IP address 192.0.2.4 to gp2.acme.com. 218 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. • Select Network > Interfaces > Tunnel and add the tunnel.1 interface and add it to a new zone called corp-vpn. Assign it to the default virtual router. • Enable User Identification on the corp-vpn zone. STEP 2 | Purchase and install a GlobalProtect subscription on each gateway if you have users who will be using the GlobalProtect app on their mobile devices or if you plan to use HIP-enabled security policy. After you purchase the GlobalProtect subscription and receive your activation code, install the license on the firewall hosting the portal as follows: 1. 2. 3. 4. Select Device > Licenses. Select Activate feature using authorization code. When prompted, enter the Authorization Code and then click OK. Verify that the license was successfully activated. STEP 3 | On each firewall hosting a GlobalProtect gateway, create security policy. This configuration requires policy rules to enable traffic flow between the corp-vpn zone and the l3-trust zone to enable access to your internal resources (Policies > Security). STEP 4 | Obtain server certificates for the interfaces hosting your GlobalProtect portal and each of your GlobalProtect gateways using the following recommendations: • (On the firewall hosting the portal or portal/gateway) Import a server certificate from a well-known, third-party CA. • (On a firewall hosting only a gateway) Use the root CA on the portal to generate a self-signed server certificate. On each firewall hosting a portal/gateway or gateway, select Device > Certificate Management > Certificates to manage certificates as follows: • Obtain a server certificate for the portal/gw1. Because the portal and the gateway are on the same interface you must use the same server certificate. The CN of the certificate must match the FQDN, gp1.acme.com. To enable clients to connect to the portal without receiving certificate errors, use a server certificate from a public CA. • Obtain a server certificate for the interface hosting gw2. Because this interface hosts a gateway only you can use a self-signed certificate. The CN of the certificate must match the FQDN, gp2.acme.com. STEP 5 | Define how you will authenticate users to the portal and the gateways. You can use any combination of certificate profiles and/or authentication profiles as necessary to ensure the security for your portal and gateways. Portals and individual gateways can also use different authentication schemes. See the following sections for step-by-step instructions: • Set Up External Authentication (authentication profile) • Set Up Client Certificate Authentication (certificate profile) • Set Up Two-Factor Authentication (token- or OTP-based) GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 219 2017 Palo Alto Networks, Inc. You will then need to reference the certificate profile and/or authentication profiles you defined in the portal and gateway configurations you define. STEP 6 | Configure the gateways. This example shows the configuration for gp1 and gp2 shown in GlobalProtect Multiple Gateway Topology. (See Configure a GlobalProtect Gateway for step-by-step instructions on creating the gateway configurations.) On the firewall hosting gp1, select Network > GlobalProtect > Gateways and configure the gateway settings as follows: Interface—ethernet1/2 IP Address—198.51.100.42 Server Certificate—GP1-server-cert.pem issued by GoDaddy Tunnel Interface—tunnel.2 IP Pool—10.31.32.3 - 10.31.32.118 On the firewall hosting gp2, select Network > GlobalProtect > Gateways and configure the gateway settings as follows: Interface—ethernet1/2 IP Address—192.0.2.4 Server Certificate—self-signed certificate, GP2-server-cert.pem Tunnel Interface—tunnel.1 IP Pool—10.31.33.3 - 10.31.33.118 STEP 7 | Configure the GlobalProtect Portals. Select Network > GlobalProtect > Portals and add the following configuration: 1. Set Up Access to the GlobalProtect Portal: Interface—ethernet1/2 IP Address—198.51.100.42 Server Certificate—GP1-server-cert.pem issued by GoDaddy 2. Define the GlobalProtect Agent Configurations: The number of client configurations you create depends on your specific access requirements, including whether you require user/group-based policy and/or HIP-enabled policy enforcement. STEP 8 | Deploy the GlobalProtect Agent Software. Select Device > GlobalProtect Client. In this example, use the procedure to Host Agent Updates on the Portal. STEP 9 | Save the GlobalProtect configuration. Click Commit on the firewall hosting the portal and the gateway(s). 220 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. GlobalProtect for Internal HIP Checking and User-Based Access When used in conjunction with User-ID and/or HIP checks, an internal gateway can be used to provide a secure, accurate method of identifying and controlling traffic by user and/or device state, replacing other network access control (NAC) services. Internal gateways are useful in sensitive environments where authenticated access to critical resources is required. In a configuration with only internal gateways, all clients must be configured with user-logon; on-demand mode is not supported. In addition, it is recommended that you configure all client configurations to use single sign-on (SSO). Additionally, because internal hosts do not need to establish a tunnel connection with the gateway, the IP address of the physical network adapter on the client system is used. In this quick config, internal gateways are used to enforce group based policies that allow users in the Engineering group access to the internal source control and bug databases and users in the Finance group to the CRM applications. All authenticated users have access to internal web resources. In addition, HIP profiles configured on the gateway check each host to ensure compliance with internal maintenance requirements, such as whether the latest security patches and antivirus definitions are installed, whether disk encryption is enabled, or whether the required software is installed. Figure 6: GlobalProtect Internal Gateway Configuration Use the following procedure to quickly configure a GlobalProtect internal gateway. STEP 1 | Create Interfaces and Zones for GlobalProtect. In this configuration, you must set up interfaces on each firewall hosting a portal and/or a gateway. Because this configuration uses internal gateways only, you must configure the portal and gateways on interfaces on the internal network. Use the default virtual router for all interface configurations to avoid having to create interzone routing. On each firewall hosting a portal/gateway: GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 221 2017 Palo Alto Networks, Inc. 1. Select an Ethernet port to host the portal/gateway and then configure a Layer3 interface with an IP address in the l3-trust security zone. (Network > Interfaces > Ethernet). 2. Enable User Identification on the l3-trust zone. STEP 2 | Purchase and install a GlobalProtect subscription for each firewall hosting an internal gateway if you have users who will be using the GlobalProtect app on their mobile devices or if you plan to use HIP-enabled security policy. After you purchase the GlobalProtect subscriptions and receive your activation code, install the GlobalProtect subscriptions on the firewalls hosting your gateways as follows: 1. 2. 3. 4. Select Device > Licenses. Select Activate feature using authorization code. When prompted, enter the Authorization Code and then click OK. Verify that the license was successfully activated. Contact your Palo Alto Networks Sales Engineer or Reseller if you do not have the required licenses. For more information on licensing, see About GlobalProtect Licenses. STEP 3 | Obtain server certificates for the GlobalProtect portal and each GlobalProtect gateway. In order to connect to the portal for the first time, the end clients must trust the root CA certificate used to issue the portal server certificate. You can either use a self-signed certificate on the portal and deploy the root CA certificate to the end clients before the first portal connection, or obtain a server certificate for the portal from a trusted CA. You can use self-signed certificates on the gateways. The recommended workflow is as follows: 1. On the firewall hosting the portal: 1. Import a server certificate from a well-known, third-party CA. 2. Create the root CA certificate for issuing self-signed certificates for the GlobalProtect components. 3. Use the root CA on the portal to generate a self-signed server certificate. Repeat this step for each gateway. 2. On each firewall hosting an internal gateway: Deploy the self-signed server certificates. STEP 4 | Define how you will authenticate users to the portal and the gateways. You can use any combination of certificate profiles and/or authentication profiles as necessary to ensure the security for your portal and gateways. Portals and individual gateways can also use different authentication schemes. See the following sections for step-by-step instructions: • Set Up External Authentication (authentication profile) • Set Up Client Certificate Authentication (certificate profile) • Set Up Two-Factor Authentication (token- or OTP-based) You will then need to reference the certificate profile and/or authentication profiles you defined in the portal and gateway configurations you define. STEP 5 | Create the HIP profiles you will need to enforce security policy on gateway access. See Host Information for more information on HIP matching. 222 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. 1. Create the HIP objects to filter the raw host data collected by the agents. For example, if you are interested in preventing users that are not up to date with required patches, you might create a HIP object to match on whether the patch management software is installed and that all patches with a given severity are up to date. 2. Create the HIP profiles that you plan to use in your policies. For example, if you want to ensure that only Windows users with up-to-date patches can access your internal applications, you might attach the following HIP profile that will match hosts that do NOT have a missing patch: STEP 6 | Configure the internal gateways. Select Network > GlobalProtect > Gateways and add the following settings: • • • • Interface IP Address Server Certificate Authentication Profile and/or Configuration Profile Notice that it is not necessary to configure the client configuration settings in the gateway configurations (unless you want to set up HIP notifications) because tunnel connections are not required. See Configure a GlobalProtect Gateway for step-by-step instructions on creating the gateway configurations. STEP 7 | Configure the GlobalProtect Portals. Although all of the previous configurations could use a Connect Method of User-logon (Always On) or On-demand (Manual user initiated connection), an internal gateway configuration must always be on and therefore requires a Connect Method of User-logon (Always On). GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 223 2017 Palo Alto Networks, Inc. Select Network > GlobalProtect > Portals and add the following configuration: 1. Set Up Access to the GlobalProtect Portal: Interface—ethernet1/2 IP Address—10.31.34.13 Server Certificate—GP-server-cert.pem issued by GoDaddy with CN=gp.acme.com 2. Define the GlobalProtect Client Authentication Configurations: Use single sign-on—enabled Connect Method—User-logon (Always On) Internal Gateway Address—california.acme.com, newyork.acme.com User/User Group—any 3. Commit the portal configuration. STEP 8 | Deploy the GlobalProtect Agent Software. Select Device > GlobalProtect Client. In this example, use the procedure to Host Agent Updates on the Portal. STEP 9 | Create the HIP-enabled and/or user/group-based security rules on your gateway(s). Add the following security rules for this example: 1. Select Policies > Security and click Add. 2. On the Source tab, set the Source Zone to l3-trust. 3. On the User tab, add the HIP profile and user/group to match. • Click Add in the HIP Profiles section and select the HIP profile MissingPatch. • Click Add in the Source User section and select the group (Finance or Engineering depending on which rule you are creating). 4. Click OK to save the rule. 5. Commit the gateway configuration. 224 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. Mixed Internal and External Gateway Configuration In a GlobalProtect mixed internal and external gateway configuration, you configure separate gateways for VPN access and for access to your sensitive internal resources. With this configuration, agents perform internal host detection to determine if they are on the internal or external network. If the agent determines it is on the external network, it will attempt to connect to the external gateways listed in its client configuration and it will establish a VPN (tunnel) connection with the gateway with the highest priority and the shortest response time. Because security policies are defined separately on each gateway, you have granular control over which resources your external and internal users have access to. In addition, you also have granular control over which gateways users have access to by configuring the portal to deploy different client configurations based on user/group membership or based on HIP profile matching. In this example, the portals and all three gateways (one external and two internal) are deployed on separate firewalls. The external gateway at gpvpn.acme.com provides remote VPN access to the corporate network while the internal gateways provide granular access to sensitive datacenter resources based on group membership. In addition, HIP checks are used to ensure that hosts accessing the datacenter are up-to-date on security patches. Figure 7: GlobalProtect Deployment with Internal and External Gateways Use the following procedure to quickly configure a mix of internal and external GlobalProtect gateways. STEP 1 | Create Interfaces and Zones for GlobalProtect. In this configuration, you must set up interfaces on the firewall hosting a portal and each firewall hosting a gateway. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 225 2017 Palo Alto Networks, Inc. Use the default virtual router for all interface configurations to avoid having to create interzone routing. On the firewall hosting the portal gateway (gp.acme.com): • Select Network > Interfaces > Ethernet and configure ethernet1/2 as a Layer 3 Ethernet interface with IP address 198.51.100.42 and assign it to the l3-untrust security zone and the default virtual router. • Create a DNS “A” record that maps IP address 198.51.100.42 to gp.acme.com. • Select Network > Interfaces > Tunnel and add the tunnel.2 interface and add it to a new zone called corp-vpn. Assign it to the default virtual router. • Enable User Identification on the corp-vpn zone. On the firewall hosting the external gateway (gpvpn.acme.com): • Select Network > Interfaces > Ethernet and configure ethernet1/5 as a Layer 3 Ethernet interface with IP address 192.0.2.4 and assign it to the l3-untrust security zone and the default virtual router. • Create a DNS “A” record that maps IP address 192.0.2.4 to gpvpn.acme.com. • Select Network > Interfaces > Tunnel and add the tunnel.3 interface and add it to a new zone called corp-vpn. Assign it to the default virtual router. • Enable User Identification on the corp-vpn zone. On the firewall hosting the internal gateways (california.acme.com and newyork.acme.com): • Select Network > Interfaces > Ethernet and configure Layer 3 Ethernet interface with IP addresses on the internal network and assign them to the l3-trust security zone and the default virtual router. • Create a DNS “A” record that maps the internal IP addresses california.acme.com and newyork.acme.com. • Enable User Identification on the l3-trust zone. STEP 2 | Purchase and install a GlobalProtect subscription for each firewall hosting a gateway (internal and external) if you have users who will be using the GlobalProtect app on their mobile devices or if you plan to use HIP-enabled security policy. After you purchase the GlobalProtect subscriptions and receive your activation code, install the GlobalProtect subscriptions on the firewalls hosting your gateways as follows: 1. 2. 3. 4. Select Device > Licenses. Select Activate feature using authorization code. When prompted, enter the Authorization Code and then click OK. Verify that the license and subscriptions were successfully activated. Contact your Palo Alto Networks Sales Engineer or Reseller if you do not have the required licenses. For more information on licensing, see About GlobalProtect Licenses. STEP 3 | Obtain server certificates for the GlobalProtect portal and each GlobalProtect gateway. In order to connect to the portal for the first time, the end clients must trust the root CA certificate used to issue the portal server certificate. 226 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. You can use self-signed certificates on the gateways and deploy the root CA certificate to the agents in the client configuration. The best practice is to generate all of the certificates on firewall hosting the portal and deploy them to the gateways. The recommended workflow is as follows: 1. On the firewall hosting the portal: 1. Import a server certificate from a well-known, third-party CA. 2. Create the root CA certificate for issuing self-signed certificates for the GlobalProtect components. 3. Use the root CA on the portal to generate a self-signed server certificate. Repeat this step for each gateway. 2. On each firewall hosting an internal gateway: • Deploy the self-signed server certificates. STEP 4 | Define how you will authenticate users to the portal and the gateways. You can use any combination of certificate profiles and/or authentication profiles as necessary to ensure the security for your portal and gateways. Portals and individual gateways can also use different authentication schemes. See the following sections for step-by-step instructions: • Set Up External Authentication (authentication profile) • Set Up Client Certificate Authentication (certificate profile) • Set Up Two-Factor Authentication (token- or OTP-based) You will then need to reference the certificate profile and/or authentication profiles you defined in the portal and gateway configurations you define. STEP 5 | Create the HIP profiles you will need to enforce security policy on gateway access. See Host Information for more information on HIP matching. 1. Create the HIP objects to filter the raw host data collected by the agents. For example, if you are interested in preventing users that are not up to date with required patches, you might create a HIP object to match on whether the patch management software is installed and that all patches with a given severity are up to date. 2. Create the HIP profiles that you plan to use in your policies. For example, if you want to ensure that only Windows users with up-to-date patches can access your internal applications, you might attach the following HIP profile that will match hosts that do NOT have a missing patch: GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 227 2017 Palo Alto Networks, Inc. STEP 6 | Configure the internal gateways. Select Network > GlobalProtect > Gateways and add the following settings: • • • • Interface IP Address Server Certificate Authentication Profile and/or Configuration Profile Notice that it is not necessary to configure the client configuration settings in the gateway configurations (unless you want to set up HIP notifications) because tunnel connections are not required. See Configure a GlobalProtect Gateway for step-by-step instructions on creating the gateway configurations. STEP 7 | Configure the GlobalProtect Portals. Although this example shows how to create a single client configuration to be deployed to all agents, you could choose to create separate configurations for different uses and then deploy them based on user/group name and/or the operating system the agent/app is running on (Android, iOS, Mac, or Windows). Select Network > GlobalProtect > Portals and add the following configuration: 1. Set Up Access to the GlobalProtect Portal: Interface—ethernet1/2 IP Address—10.31.34.13 Server Certificate—GP-server-cert.pem issued by GoDaddy with CN=gp.acme.com 2. Define the GlobalProtect Client Authentication Configurations: Internal Host Detection—enabled Use single sign-on—enabled Connect Method—User-logon (Always On) External Gateway Address—gpvpn.acme.com Internal Gateway Address—california.acme.com, newyork.acme.com User/User Group—any 3. Commit the portal configuration. STEP 8 | Deploy the GlobalProtect Agent Software. Select Device > GlobalProtect Client. In this example, use the procedure to Host Agent Updates on the Portal. 228 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 2017 Palo Alto Networks, Inc. STEP 9 | Create security policy rules on each gateway to safely enable access to applications for your VPN users. • Create security policy (Policies > Security) to enable traffic flow between the corp-vpn zone and the l3-trust zone. • Create HIP-enabled and user/group-based policy rules to enable granular access to your internal datacenter resources. • For visibility, create rules that allow all of your users web-browsing access to the l3-untrust zone, using the default security profiles to protect you from known threats. STEP 10 | Save the GlobalProtect configuration. Click Commit on the portal and all gateways. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs © 229 2017 Palo Alto Networks, Inc. 230 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Quick Configs GlobalProtect Architecture This section outlines an example reference architecture for deploying GlobalProtect™ which secures internet traffic and provides secure access to corporate resources. The reference architecture and guidelines described in this section provide a common deployment scenario. Before adopting this architecture, identify your corporate security, infrastructure manageability, and end user experience requirements and deploy GlobalProtect based on those requirements. Although the requirements may be different for each enterprise, you can leverage the common principles and design considerations outlined in this document along with best practice configuration guidelines to meet your enterprise security needs. > GlobalProtect Reference Architecture Topology on page 233 > GlobalProtect Reference Architecture Features on page 235 > GlobalProtect Reference Architecture Configurations on page 237 231 232 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Architecture © 2017 Palo Alto Networks, Inc. GlobalProtect Reference Architecture Topology • GlobalProtect Portal on page 233 • GlobalProtect Gateways on page 233 GlobalProtect Portal In this topology, a PA-3020 in the co-location space functions as a GlobalProtect portal. Employees and contractors can authenticate to the portal using two-factor authentication (2FA) consisting of Active Directory (AD) credentials and a one-time password (OTP). The portal deploys GlobalProtect client configurations based on user and group membership and operating system. By configuring a separate portal client configuration that applies to a small group or set of pilot users, you can test features before rolling them out to a wider user base. Any client configuration containing new features—such as the Enforce GlobalProtect or Simple Certificate Enrollment Protocol (SCEP) features which were made available with PAN-OS 7.1 and content updates that followed—is enabled in the pilot configuration first and validated by those pilot users, before it is made available to other users. The GlobalProtect portal also pushes configurations to GlobalProtect satellites. This configuration includes the GlobalProtect gateways to which satellites can connect and establish a site-to-site tunnel. GlobalProtect Gateways The PA-3020 in the co-location space (mentioned previously) also doubles as a GlobalProtect gateway (the Santa Clara Gateway). 10 additional gateways are deployed in Amazon Web Services (AWS) and the Microsoft Azure public cloud. The regions or POP locations where these AWS and Azure gateways are deployed are based on the distribution of employees across the globe. • Santa Clara Gateway—Employees and contractors can authenticate to the Santa Clara Gateway (PA-3020 in the co-location space) using 2FA. This gateway requires users to provide their Active GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Architecture © 233 2017 Palo Alto Networks, Inc. Directory credentials and their OTP. Because this gateway protects sensitive resources, it is configured as a manual-only gateway. As a result, users do not connect to this gateway automatically and must manually choose to connect to this gateway. For example, when users connect to AWS-Norcal, which is not a manual-only gateway, some sensitive internal resources are not accessible. The user must then manually switch to and authenticate with the Santa Clara Gateway to access these resources. In addition, the Santa Clara Gateway is configured as a Large Scale VPN (LSVPN) tunnel termination point for all satellite connections from gateways in AWS and Azure. The Santa Clara Gateway is also configured to set up an Internet Protocol Security (IPSec) tunnel to the IT firewall in corporate headquarters. This is the tunnel that provides access to resources in the corporate headquarters. • Gateways in Amazon Web Services and Microsoft Azure—This gateway requires 2FA: a client certificate and Active Directory credentials. The GlobalProtect portal distributes the client certificate that is required to authenticate with these gateways using the GlobalProtect SCEP feature. These gateways in the public cloud also act as GlobalProtect satellites. They communicate with the GlobalProtect portal, download the satellite configuration, and establish a site-to-site tunnel with the Santa Clara Gateway. GlobalProtect satellites initially authenticate using serial number, and subsequently authenticate using certificates. • Gateways Inside Corporate Headquarters—Within the corporate headquarters, three firewalls function as GlobalProtect gateways. These are internal gateways and do not require endpoints to set up a tunnel. Users authenticate to these gateways using their Active Directory credentials. These internal gateways use GlobalProtect to identify the User-ID and to collect Host Information Profile (HIP) from the endpoints. To make the end user experience as seamless as possible, you can configure these internal gateways to authenticate users using certificates provisioned by SCEP or using Kerberos service tickets. 234 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Architecture © 2017 Palo Alto Networks, Inc. GlobalProtect Reference Architecture Features • End User Experience on page 235 • Management and Logging on page 235 • Monitoring and High Availability on page 236 End User Experience End users who are remote (not inside the corporate network) connect to one of the gateways in AWS or Azure. When you configure the GlobalProtect portal client configuration, assign equal priority to the gateways. With this configuration, the gateway to which users connect depends on the SSL response time of each gateway measured on the endpoint during the tunnel set-up time. For example, a user in Australia would typically connect to the AWS-Sydney Gateway. Once the user is connected to AWS-Sydney, GlobalProtect client tunnels all traffic from the endpoint to the AWSSydney firewall for inspection. GlobalProtect sends traffic to public internet sites directly via the AWSSydney Gateway and tunnels traffic to corporate resources through a site-to-site tunnel between the AWS-Sydney Gateway and the Santa Clara Gateway, and then through an IPSec site-to-site tunnel to the corporate headquarters. This architecture is designed to reduce any latency the user may experience when accessing the internet. If the AWS-Sydney Gateway (or any gateway closer to Sydney) was unreachable, the GlobalProtect client would back-haul the internet traffic to the firewall in the corporate headquarters and cause latency issues. Active directory servers reside inside the corporate network. When remote end users authenticate, the GlobalProtect client sends authentication requests through the site-to-site tunnel in AWS/Azure to the Santa Clara Gateway. The gateway then forwards the request through an IPSec site-to-site tunnel to the Active Directory Server in corporate headquarters. To reduce the time it takes for remote user authentication and tunnel set up, consider replicating the Active Directory Server and making it available in AWS. End users inside the corporate network authenticate to the three internal gateways immediately after they log in; The GlobalProtect client sends the HIP report to these internal gateways. When users are inside the office on the corporate network, they must meet the User-ID and HIP requirements to access any resource at work. Management and Logging In this deployment, you can manage and configure all firewalls from Panorama, which is deployed in the colocation space. To provide consistent security, all firewalls in AWS and Azure use the same security policies and configurations. To simplify configuration of the gateways, Panorama also uses one device group and one template. In this deployment, all gateways forward all logs to Panorama. This enables you to monitor network traffic or troubleshoot issues from a central location instead of requiring you to log in to each firewall. When software updates are required, you can use Panorama to deploy the software updates to all firewalls. Panorama first upgrades one or two firewalls and verifies whether the upgrade was successful before updating the remaining firewalls. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Architecture © 235 2017 Palo Alto Networks, Inc. Monitoring and High Availability To monitor the firewalls in this deployment, you can use Nagios, an open-source server, network, and log monitoring software. Configure Nagios to periodically verify the response from the portal and the gateways' pre-login page and send an alert if the response does not match the expectations. You can also configure GlobalProtect Simple Network Management Protocol (SNMP) Management Information Base (MIB) objects to monitor gateway usage. In this deployment there is only one instance of the GlobalProtect portal. If the portal becomes unavailable, new users (who have never connected to the portal before) will not be able to connect to GlobalProtect. However, existing users can use the cached portal client configuration to connect to one of the gateways. Multiple virtual machine (VM) firewalls in AWS configured as GlobalProtect gateways provide gateway redundancy. Therefore, configuring gateways as a high availability (HA) pair is not required. 236 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Architecture © 2017 Palo Alto Networks, Inc. GlobalProtect Reference Architecture Configurations To align your deployment with the reference architecture, review the following configuration checklists. • Gateway Configuration on page 237 • Portal Configuration on page 237 • Policy Configurations on page 237 Gateway Configuration Disable split tunneling. To do this, ensure there are no Access Routes specified in Agent > Client Settings > Split Tunnel settings. See Configure a GlobalProtect Gateway on page 72. Enable No direct access to local network in Agent > Client Settings > Split Tunnel. See Configure a GlobalProtect Gateway on page 72. Enable the gateway to Accept cookie for authentication override. See Configure a GlobalProtect Gateway on page 72. Portal Configuration Configure the Connect Method as Always-on (User logon). See Customize the GlobalProtect Agent. Set Use Single Sign-On (Windows only) to Yes. See Customize the GlobalProtect Agent. Configure the portal to Save User Credentials (set the value to Yes). See Define the GlobalProtect Agent Configurations. Enable the portal to Accept cookie for authentication override. See Define the GlobalProtect Agent Configurations. Configure the Cookie Lifetime as 20 hours. See Define the GlobalProtect Agent Configurations. Enforce GlobalProtect for network access. See Customize the GlobalProtect Agent. When Enforce GlobalProtect for Network Access is enabled, allow users to disable the GlobalProtect agent with a passcode. See Customize the GlobalProtect Agent. Configure Internal Host Detection. See Define the GlobalProtect Agent Configurations. Enable the Collect HIP Data option in Data Collection. See Define the GlobalProtect Agent Configurations. Distribute and install the SSL Forward Proxy CA certificate used for SSL Decryption. See Define the GlobalProtect Agent Configurations. Policy Configurations Configure all firewalls to use security policies and profiles based on the Best Practice Internet Gateway Security Policy. In this reference deployment, this includes the Santa Clara Gateway in the co-location space and gateways in the AWS/Azure public cloud. Enable SSL Decryption on all gateways in AWS and Azure. Configure Policy-Based Forwarding rules for all gateways in AWS to forward traffic to certain websites through the Santa Clara Gateway. This ensures that sites like www.stubhub.com and www.lowes.com that block traffic from AWS IP address ranges are still accessible when users connect to gateways in AWS.

GlobalProtect also supports the ability to enable and require the GlobalProtect agent to always attempt to set up IPSec tunnel first before falling back to SSL tunnel. With an IPSec tunnel, the GlobalProtect agent uses SSL/TLS to exchange encryption and authentication algorithms and the keys. The selection of cipher suite that GlobalProtect uses to secure the SSL/TLS tunnel depend on: • SSL/TLS versions accepted by the gateway—The GlobalProtect portal and gateways can restrict the list of cipher suites available for the client using SSL/TLS profiles. On the firewall, you create the SSL/ TLS profile by specifying the certificate and the allowed protocol versions and associate that to the GlobalProtect portal and gateway. • Algorithm of the server certificate of the gateway—The operating system of the endpoint determines what cipher suites the GlobalProtect agent includes in its Client Hello message. As long as the GlobalProtect agent includes the cipher suite that gateway prefers to use, the gateway will select that cipher suite for the SSL session. The order of cipher suites within the Client Hello message does not affect the cipher suite selection: The gateway selects the cipher suite based on the SSL/TLS service profile and the algorithm of the gateway server certificate and its preferred list. You select the service profile from the GlobalProtect gateway authentication configuration. GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Cryptography © 241 2017 Palo Alto Networks, Inc. Cipher Exchange Between the GlobalProtect Agent and Gateway The following figure displays the exchange of ciphers between GlobalProtect gateways and GlobalProtect agents when creating the VPN tunnel. Figure 8: Cipher Exchange Between the Agent and the Gateway The following table describes these stages in more detail. Table 7: Cipher Exchange Between the Agent and Gateway Communication Stage Description 1. Client Hello The agent proposes a list of cipher suites depending on the OS of the endpoint. 2. Server Hello The gateway selects the cipher suite proposed by the agent. When selecting the ciphers to set up the tunnel, the gateway ignores both the number and 242 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Cryptography © 2017 Palo Alto Networks, Inc. Communication Stage Description order of cipher suites proposed by the agent and instead relies on the SSL/ TLS versions and algorithm of the gateway server certificate and its preferred list (as described in About GlobalProtect Cipher Selection). 3. Optional Client Certificate The gateway can optionally request a client certificate from the agent to use to trust the identity of the user or endpoint. 4. SSL Session After setting up the SSL/TLS session, the agent authenticates with the gateway and requests the gateway configuration (Get-Config-Request). To request the configuration, the agent proposes the encryption and authentication algorithms and other settings such as preferred IP address for the tunnel interface. The gateway responds to the request and selects the encryption and authentication algorithm to use based on the configuration of the GlobalProtect IPSec Crypto Profile (Get-Config-Response). The following table displays an example of the cipher exchange between an agent on a Mac endpoint and the gateway. Table 8: Example: Cipher Exchange for Mac Endpoints Communication Stage Example: Mac Endpoints 1. Client Hello TLS 1.2 37 Cipher Suites (Reference: TLS Ciphers Supported by GlobalProtect Agents on Mac Endpoints) 2. Server Hello • When GlobalProtect uses an ECDSA certificate and TLS 1.2 is accepted, the SSL session uses ECDSA-AES256-CBC-SHA. • When GlobalProtect uses an RSA certificate and TLS 1.2 is accepted, the SSL session uses RSA-AES256-CBC-SHA256. 3.

Because AES-GCM encryption algorithms (aes-128-gcm and aes-256-gcm) natively provide ESP integrity protection, the sha1 authentication algorithm is ignored for these ciphers even though it is required during configuration. 244 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Cryptography © 2017 Palo Alto Networks, Inc.

Ciphers Used to Set Up IPSec Tunnels GlobalProtect can restrict and/or set preferential order for what encryption and authentication algorithm the GlobalProtect agent can use for the IPSec tunnel. The algorithms and preferences are defined in the GlobalProtect IPSec Crypto Profile that you configure when you set up the tunnel settings of the GlobalProtect gateway. When the GlobalProtect agent sets up an SSL session with GlobalProtect gateway. The cipher suite used for this SSL session is governed by the SSL/TLS profile configured on the gateway and the type of algorithm GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Cryptography © 251 2017 Palo Alto Networks, Inc. used by the gateway certificate. After the SSL session is established, the GlobalProtect agent initiates a VPN tunnel setup by requesting the configuration over SSL. Using the same SSL session, the GlobalProtect gateway responds with the encryption and authentication algorithms, keys, and SPIs the agent should use to set up the IPSec tunnel. AES-GCM is recommended for more secure requirements. To provide data integrity and authenticity protection, the aes-128-cbc cipher requires the SHA1 authentication algorithm. Because AES-GCM encryption algorithms (aes-128-gcm and aes-256-gcm) natively provide ESP integrity protection, the SHA1 authentication algorithm is ignored for these ciphers even though it is required during configuration. The GlobalProtect IPSec Crypto Profile that you configured on the gateway determines the encryption and authentication algorithm used to set up the IPSec tunnel. The GlobalProtect gateway responds with the first matching encryption algorithm listed in the IPSec Crypto Profile that matches the agent’s proposal. The GlobalProtect agent then attempts to set up a tunnel based on the response from the gateway. 252 GLOBALPROTECT ADMINISTRATOR'S GUIDE | GlobalProtect Cryptography © 2017 Palo Alto Networks, Inc. SSL APIs GlobalProtect agent uses both OpenSSL and native system APIs for doing the SSL Handshake. Operations such as the GlobalProtect gateway latency measurement—used by GlobalProtect to select the best gateway —gateway logout, and sending the HIP check message and report are all performed over an SSL session that is set up using OpenSSL library. While operations like gateway pre-login, login and get-config are all done over the SSL session that is set up using the native system API.
