System and method for wireless LAN dynamic channel change with honeypot trap
A network security system includes a system data store capable of storing a variety of data associated with a wireless computer network and communication transmitted thereon, a communication interface supporting wireless communication over the wireless computer network and a system processor. Configuration data associated with an access point on a wireless computer network potentially compromised by an intruder is received. Information contained within and/or derived from the received configuration data is stored. Communication with the intruder is continued by emulating the identification characteristics of the potentially compromised access point. A channel change request is transmitted to the potentially compromised access point to reroute communication between the potentially compromised access point and authorized stations such that communications may continue on a different channel.
