Abstract: A method for preventing Medium Access Control (MAC) spoofing attacks in a communication network may include obtaining, by a protection layer, a connecting request for connecting a terminal to the communication network. The method may include issuing, by the protection layer, a MAC authentication request to a Network Admission Control (NAC) server, the MAC authentication request may be a request to determine whether a MAC address of the terminal is whitelisted. The method may include responding, by the NAC server, to the MAC authentication request of the protection layer by allowing the terminal to join the communication network based on whether the MAC address of the terminal is whitelisted. The method may include sending, by the NAC server, a log message to a log analyzer server, the log message including a result identifying whether the MAC address of the terminal is whitelisted.
