A mobile ad-hoc network (MANET 10, 20, 30, 40, 50, 60) may include a plurality for nodes for transmitting data therebetween using a media access layer (MAC), where each of the nodes has a respective MAC address associated therewith. The MANET may also include a policing node (13, 23, 33, 43, 53, 63) for detecting intrusions (14, 24, 34, 44, 54, 64) into the MANET by monitoring transmissions among the plurality of nodes 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 node 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.
