What occurs when a rogue access point is added to a WLAN?
-
Authorized access points can transmit excess traffic to rogue access points to help alleviate congestion.
-
Unauthorized users can gain access to internal servers, thus causing a security hole.
-
All traffic that uses the same channel as the rogue access point will be encrypted.
-
All traffic that uses the same channel as the rogue access point will be required to authenticate.
A rogue access point is an unauthorized AP installed on a network without the IT department's knowledge, creating a security vulnerability. It allows unauthorized users to bypass network security and gain access to internal resources. Rogue APs do not alleviate congestion (option A), they do not encrypt traffic (option C - encryption is a function of legitimate APs using WPA/WPA2), and they definitely do not enforce authentication (option D - they bypass security). The primary risk is the security hole they create.
