Rogue AP

This chapter shows you how to set up Rogue Access Point (AP) detection and containment.

10.1 Rogue AP Detection Overview

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 potentially open holes in the network security. Attackers can take advantage of a rogue AP’s weaker (or non-existent) security to gain illicit access to the network, or set up their own rogue APs in order to capture information from wireless clients.

Conversely, a friendly AP is one that the NXC network administrator regards as non- threatening. This does not necessarily mean the friendly AP must belong to the network managed by the NXC; rather, it is any unmanaged AP within range of the NXC’s own wireless network that is allowed to operate without being contained. This can include APs from neighboring companies, for example, or even APs maintained by your company’s employees that operate outside of the established network.
