This chapter discusses rogue wireless access points and how to configure the 
NWA’s rogue AP detection feature.

Rogue APs are wireless access points operating in a network’s coverage area that 
are not under the control of the network’s administrators, and can open up holes 
in a network’s security. Attackers can take advantage of a rogue AP’s weaker (or 
non-existent) security to gain access to the network, or set up their own rogue 
APs in order to capture information from wireless clients. If a scan reveals a rogue 
AP, you can use commercially-available software to physically locate it.

Note that it is not necessary for a network to have a legitimate wireless LAN 
component for rogue APs to open the network to an attacker. In this case, any AP 
detected can be classified as rogue.

Figure 113   Rogue AP Example

In the example above, a corporate network’s security is compromised by a rogue 
AP (R) set up by an employee at his workstation in order to allow him to connect 
his notebook computer wirelessly (A). The company’s legitimate wireless network
