A mobile ad-hoc network (MANET 10, 20, 30, 40, 50, 60) may include a plurali ty for nodes for transmitting data therebetween using a media access layer (MAC ), where each of the nodes has a respective MAC address associated therewith. T he MANET may also include a policing node (13, 23, 33, 43, 53, 63) for detectin g intrusions (14, 24, 34, 44, 54, 64) into the MANET by monitoring transmissio ns among the plurality of nodes to detect frame check sequence (FCS) errors fro m a MAC address, and generating an intrusion alert based upon detecting a numb er of FCS errors for the MAC address exceeding a threshold. The policing node m ay 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.
