Security Maintenance
To ensure proper and secure running of the telepresence system, you need to know application
layer accounts and their default passwords and security maintenance methods, as well as
security maintenance principles and policies at the system, network, and management layers.
10.1 Overview
This section describes the overall purpose of security maintenance, as well as specific
purposes of security maintenance at the application layer, system layer, network layer, and
management layer.
10.1.1 Purpose of Security Maintenance
Security management regulations should be established based on security maintenance
suggestions and problems found in daily operations to ensure proper and secure running of the
videoconferencing system.
Now application systems face severe security threats. Once problems occur, business might be
disturbed, profits reduced, or even systems break down. Users must build up and maintain the
application system security from different layers, and discover and solve potential threats in
advance.
Besides, considering the endless emergence of safety threats, a mere dependence on
technology can hardly ensure the application system security. Users must build up a safety
management system based on security maintenance suggestions and problems they found
during the use of the endpoint to ensure a smooth and safe operation of the endpoint.
10.1.2 What Is Layered Security Maintenance
Service systems must be maintained at the application layer, system layer, network layer, and
management layer.
According to the target and purpose of security maintenance, maintenance personnel must
safeguard the service system from different layers.
Application Layer
Security maintenance of the application layer is to protect the endpoint and its web
management system so that they can provide services to users with a smooth operation.

10 Security Maintenance
System Layer
Security maintenance of the system layer is to ensure a smooth operation of the operating
system, which can support the operation of application software.
Network Layer
Security maintenance of the network layer is to ensure that network devices, such as the
switch, router, and firewall, function properly and that security strategies are implemented at
the network layer.
Management Layer
Security maintenance of the management layer is to strengthen people's management and
avoid threats. Maintenance from the management layer involves the maintenance operations
at all preceding layers.
10.2 Application Layer Security
This section describes application layer accounts and their default passwords and functions, as
well as security configurations at the application layer.
10.2.1 Application Layer Account List
This section describes application layer accounts and their default passwords, functions, and
configuration methods. To ensure account security, you are advised to change the password at
the first login and regularly change the password afterward.
Administrator Password of the Remotely Controlled UI
This section describes the default password of the remotely controlled UI administrator and
relevant settings and precautions.
The default administrator password of remote control interface is 12345678. To improve
device security, set a password at your first login and regularly change the password
afterward.
It is recommended that you set a complex password. A simple or empty password brings security risks.
To set the administrator password for logging in to the remote control interface, perform the
following steps:

On the remotely controlled UI, choose System Settings > More > Administrator
Password, and set the password.

On the web interface, choose System Settings > Security > GUI, and set the password.
You need the administrator password to access the System Settings page. Contact the system
administrator to obtain the password.
Web Management Account
Web login accounts are classified into admin, and api. Keep your administrator account and
password secure to prevent personal information disclosure.

The account and password can be used to log in to the web interface, Telnet, and SSH.

Rights except user name and password change policies are the same: able to read and
write other configuration items; and able to invoke all HTTP interfaces.
The differences of admin, and api accounts lie in the rights in changing other user names and
passwords:

The admin account can be used to change the user name and password of the api
account with the verification of the old password of the admin account.

The api account can be used to change the user name and password of the admin
account with the verification of the old password of the api account.

System Connection Whitelist
The whitelist helps enhance videoconferencing security. After you configure a whitelist, only
devices with the IP addresses specified in the whitelist can connect to the endpoint.
Set the whitelist under the guidance of technical support engineers.
The endpoint whitelist is empty by default. That is, all IP addresses are allowed to connect to
the endpoint. If the endpoint is deployed on a public network, it is recommended that you add
frequently-used IP addresses or IP address segments to the whitelist. This approach helps
defend against potential network threats, such as flood attack and slow HTTP attack. You
must add the IP addresses of the following devices to the whitelist:

PC that is used to access the endpoint web interface

Videoconferencing MCU

SMC2.0

Possible Cause
Solution
Your site and a remote site
cannot call each other using
site numbers.
Your site or the remote site
has not registered with an
SC. An SC is responsible for
translating site numbers into
IP addresses. If either your
site or the remote site does
not register with an SC, the
translation cannot be
implemented, and your site
cannot place a call to the
remote site using the site
number.
Verify SC registration
settings and register your
site and the remote site with
an SC.
If a remote site places a call
to your site by site number,
it will receive a message
from the SC indicating that
your site has not registered
with the SC, and the call
cannot be set up.
The local or remote
