Abstract:
A wireless local or metropolitan area network may include a plurality of stations for transmitting data therebetween using a media access layer (MAC), where each of the stations has a respective MAC address associated therewith. The wireless network may also include a policing station for detecting intrusions into the wireless network by monitoring transmissions among the plurality of stations to detect frame check sequence (FCS) errors from a MAC address, and generating an intrusion alert based upon detecting a number of FCS errors for the MAC address exceeding a threshold. The policing station may also detect intrusions based upon one or more of failed MAC address authentications, illegal network allocation vector (NAV) values, and unexpected contention or contention-free operation.
