CHAPTER 15
Rogue AP Detection
15.1 Overview
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.

AP (R) set up by an employee at his workstation in order to allow him to connect
