【Abstract】 Due to some design flaws in ARP protocol, the ethernet is vulnerable to the ARP spoofing attack. Recently,the ARP virus attack is breaking out in a large scale in the campus network, seriously affects the regular operation ofthe campus network, and brings much pressure to the maintenance and control of the network. This paper proposes theprinciples of the ARP protocol,the theory of ARP spoofing attack, the tactics to detect ARP spoofing attack,and finallyproposes a quick solution for the problem of defend ARP spoofing attack in the VLAN by using Ruijie Layer-3 switch.更多还原
