The friendly AP list displays details of all the access points in your area that you 
know are not a threat. If you have more than one AP in your network, you need to 
configure this list to include your other APs. If your wireless network overlaps with 
that of a neighbor (for example) you should also add these APs to the list, as they 
do not compromise your own network’s security. If you do not add them to the 
friendly AP list, these access points will appear in the Rogue AP list each time the 
NWA scans.
“Honeypot” Attack
Rogue APs need not be connected to the legitimate network to pose a severe 
security threat. In the following example, an attacker (X) is stationed in a vehicle 
outside a company building, using a rogue access point equipped with a powerful 
antenna. By mimicking a legitimate (company network) AP, the attacker tries to 
capture usernames, passwords, and other sensitive information from 
unsuspecting clients (A and B) who attempt to connect. This is known as a 
“honeypot” attack.
Figure 109   “Honeypot” Attack
If a rogue AP in this scenario has sufficient power and is broadcasting the correct 
SSID (Service Set IDentifier) clients have no way of knowing that they are not 
associating with a legitimate company AP. The attacker can forward network traffic 
from associated clients to a legitimate AP, creating the impression of normal 
service. This is a variety of “man-in-the-middle” attack.
