Abstract
A wireless local or metropolitan area network may include a plurality of stations for transmitting data therebetween and a policing station. The policing station may detect intrusions into the wireless network by monitoring transmissions among the plurality of stations to detect transmissions during an unauthorized period and generate an intrusion alert based thereon. The policing station may also detect intrusions based upon one or more of integrity check values which do not correspond with respective data packets, usage of non-consecutive media access control (MAC) sequence numbers by a station, and collisions of packet types and/or MAC addresses.
