By analyzing the principle of ARP spoofing attacks, this paper introduces the method of locating ARP attack sources and puts forward a scheme of ARP virus prevention against the engine room. The main measures are: sub-VLAN; in the three-tier equipment and the host to achieve two-way binding; use ARP attack prevention function of access switches; computer room to do computer security protection; install ARP virus prevention software.
