How to Cheat at Securing a Wireless Network

Solutions Fast Track

Enabling Security Features on a Linksys WRT54G, a D-Link DI-624 AirPlus Xtreme G, an Apple Airport Extreme, and a Cisco 1100 Series Access Point

These have been consolidated because they are the recommendations for securing any AP/router and are not specific to a particular hardware:

Assigning a unique SSID to your wireless network is the first security measure that you should take. Any attacker with a default configuration profile is able to associate with an access point that has a default SSID. Assigning a unique SSID in and of itself doesn t offer much protection, but it is one layer in your wireless defense.

Many attackers use active wireless scanners to discover target wireless networks. Active scanners rely on the access point beacon to locate it.This beacon broadcasts the SSID to any device that requests it. Disabling SSID broadcast makes your access point invisible to active scanners. Because your access point can still be discovered by passive wireless scanners, this step should be used in conjunction with other security measures.

Wired Equivalent Privacy (WEP) encryption, at a minimum, should be used on your home wireless network. Although there are tools available that make it possible to crack WEP, the fact that encryption is enabled on the access point may be the difference between an attack on your AP or your neighbor s. Adequate security for these networks is provided by 128-bit WEP.
