Abstract
A method, performed by at least one processor, for protecting a front-haul link from a Man-in-the-Middle (MiTM) attack in a network communication system includes receiving, through a port of an authenticator, an authentication request for port authentication from a supplicant via an Ethernet Frame, obtaining, by the authenticator from the Ethernet frame, a hop count corresponding to a number of hops in a transmission path of the Ethernet frame between the supplicant and the authenticator, comparing the hop count to a predetermined threshold to determine whether the port should be disabled, and disabling the port based on the hop count being greater than the predetermined threshold.
