Many industry researchers say the state of VoIP security is as bad today as it was two years ago, with many adopters relying on protocols that are easy to attack. VOIP sessions are particularly vulnerable to man-in-the-middle attacks where frames sent back and forth between a user's radio NIC and access point during the association process are monitored. As a result, the attacker can learn information about the radio card and access point, such as IP address of both devices, association ID for the radio NIC, and so on. With this information, the attacker can setup a rogue access point (on a different radio channel) closer to a particular user to force the user's radio NIC to reassociate with the rogue access point.

Addressing this problem will improve once VoIP communications professionals and IT security specialists can learn the other’s technology.
