Chapter 2 Wireless Security Checklist

Wireless-G Router for Mobile Broadband
Chapter 2:
Wireless Security Checklist
Wireless networks are convenient and easy to install, so
homes with high-speed Internet access are adopting them
at a rapid pace. Because wireless networking operates by
sending information over radio waves, it can be more
vulnerable to intruders than a traditional wired network.
Like signals from your cellular or cordless phones, signals
from your wireless network can also be intercepted. Since
you cannot physically prevent someone from connecting
to your wireless network, you need to take some additional
steps to keep your network secure.
1. Change the default wireless
network name or SSID
Wireless devices have a default wireless network name
or Service Set Identifier (SSID) set by the factory. This
is the name of your wireless network, and can be up
to 32 characters in length. Linksys wireless products
use linksys as the default wireless network name. You
should change the wireless network name to something
unique to distinguish your wireless network from other
wireless networks that may exist around you, but do not
use personal information (such as your Social Security
number) because this information may be available for
anyone to see when browsing for wireless networks.
2. Change the default password
For wireless products such as access points, routers, and
gateways, you will be asked for a password when you
want to change their settings. These devices have a default
password set by the factory. The Linksys default password
is admin. Hackers know these defaults and may try to
use them to access your wireless device and change your
network settings. To thwart any unauthorized changes,
customize the device’s password so it will be hard to
guess.
3. Enable MAC address filtering
Linksys routers and gateways give you the ability to
enable Media Access Control (MAC) address filtering. The
MAC address is a unique series of numbers and letters
assigned to every networking device. With MAC address
filtering enabled, wireless network access is provided
solely for wireless devices with specific MAC addresses.
For example, you can specify the MAC address of each
computer in your home so that only those computers can
access your wireless network.
4. Enable encryption
Encryption protects data transmitted over a wireless
network. Wi-Fi Protected Access (WPA/WPA2) and Wired
Equivalency Privacy (WEP) offer different levels of security
for wireless communication.
A network encrypted with WPA/WPA2 is more secure
than a network encrypted with WEP, because WPA/WPA2
uses dynamic key encryption. To protect the information
as it passes over the airwaves, you should enable the
highest level of encryption supported by your network
equipment.
WEP is an older encryption standard and may be the
only option available on some older devices that do not
support WPA.
General Network Security Guidelines
Wireless network security is useless if the underlying
network is not secure.
Password protect all computers on the network and
individually password protect sensitive files.
Change passwords on a regular basis.
Install anti-virus software and personal firewall
software.
Disable file sharing (peer-to-peer). Some applications
may open file sharing without your consent and/or
knowledge.
Additional Security Tips
Keep wireless routers, access points, or gateways away
from exterior walls and windows.
Turn wireless routers, access points, or gateways
off when they are not being used (at night, during
vacations).
Use strong passphrases that are at least eight characters
in length. Combine letters and numbers to avoid using
standard words that can be found in the dictionary.

Authentication Type The default is set to Auto, which
allows either Open System or Shared Key authentication
to be used. With Open System authentication, the sender
and the recipient do NOT use a WEP key for authentication.
With Shared Key authentication, the sender and recipient
use a WEP key for authentication. Select Shared Key to
only use Shared Key authentication.
Basic Rate The Basic Rate setting is not actually one rate
of transmission but a series of rates at which the Router
can transmit. The Router will advertise its Basic Rate to
the other wireless devices in your network, so they know
which rates will be used. The Router will also advertise that
it will automatically select the best rate for transmission.
The default is Default, when the Router can transmit at
all standard wireless rates (1-2Mbps, 5.5Mbps, 11Mbps,
18Mbps, and 24Mbps). Other options are 1-2Mbps, for
use with older wireless technology, and All, when the
Router can transmit at all wireless rates. The Basic Rate
is not the actual rate of data transmission. If you want to
specify the Router’s rate of data transmission, configure
the Transmission Rate setting.
Transmission Rate The rate of data transmission should
be set depending on the speed of your wireless network.
You can select from a range of transmission speeds, or you
can select Auto to have the Router automatically use the
fastest possible data rate and enable the Auto-Fallback
feature. Auto-Fallback will negotiate the best possible
connection speed between the Router and a wireless
client. The default is Auto.
CTS Protection Mode The Router will automatically
use CTS (Clear-To-Send) Protection Mode when your
Wireless-N and Wireless-G products are experiencing
severe problems and are not able to transmit to the
Router in an environment with heavy 802.11b traffic. This
function boosts the Router’s ability to catch all Wireless-
N and Wireless-G transmissions but will severely decrease
performance. The default is Auto.
Beacon Interval Enter a value between 1 and 65,535
milliseconds. The Beacon Interval value indicates the
frequency interval of the beacon. A beacon is a packet
broadcast by the Router to synchronize the wireless
network. The default is 100.
DTIM Interval This value, between 1 and 255, indicates
the interval of the Delivery Traffic Indication Message
(DTIM). A DTIM field is a countdown field informing
clients of the next window for listening to broadcast
and multicast messages. When the Router has buffered
broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Its clients
hear the beacons and awaken to receive the broadcast
and multicast messages. The default is 1.
Fragmentation Threshold This value specifies the
maximum size for a packet before data is fragmented
into multiple packets. If you experience a high packet
error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low
may result in poor network performance. Only minor
reduction of the default value is recommended. In most
cases, it should remain at its default of 2346.
Chapter 3 Advanced Configuration

Wireless-G Router for Mobile Broadband
RTS Threshold Should you encounter inconsistent data
flow, only minor reduction of the default value, 2347, is
recommended. If a network packet is smaller than the
preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Router sends Request to Send (RTS)
frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS, the
wireless station responds with a Clear to Send (CTS) frame
to acknowledge the right to begin transmission. The RTS
Threshold value should remain at its default value of
2347.
