To protect your network, change the default wireless network name to a
unique name to distinguish your wireless network from other wireless
networks that may exist around you.
When choosing names, 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.
•
Change the default password.
For wireless products such as access points, routers, and gateways, you
are asked for a password when you want to change their settings. These
devices have a default password. The default password is often
cisco
.
Hackers know these default values and may try to use them to access your
wireless device and change your network settings. To thwart unauthorized
access, customize the device’s password so it is hard to guess.
•
Enable MAC address filtering.
Cisco routers and gateways give you the ability to enable 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 network so that
only those computers can access your wireless network.
•
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. Currently, devices
that are Wi-Fi certified are required to support WPA2, but are not required
to support WEP.
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, 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.
•
Keep wireless routers, access points, or gateways away from exterior walls
and windows.
