17.3 Technical Reference

The following section contains additional technical information about the features described in this
chapter.
Rogue APs
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.

rogue AP uses inferior security that is easily broken by an attacker (X) running readily available
