Research on ARP Attack and Defense

The network anomalies, illegal control, data theft and tampering caused by ARP attack have made ARP attack and defense a focus in the field of network security. In response to the common ARP attack in local area networks, the paper first analyzes the ARP protocol and its shortcomings. On this basis, the basic principles and common simulation methods of ARP attack were elaborated. Finally, the current mainstream ARP attack detection and defense methods were discussed in conjunction with network management.
