Study on ARP spoofing attack detection and defense technology

Attackers using ARP spoofing attack network segment host In the LAN,which threaten the LAN security seriously.This paper analyzed the common tricks such as monitor,intercept,and malicious attacks which attackers used,and summarized the IP matched methods based on ARP cheat theory,data frame detection method,Echo time method,ARP response analysis method,tools detection method and so on.A prevent ARP spoofing algorithm is proposed in this paper,which made use of ARP cache update policy,switching equipment control and other strategies to prevent ARP spoofing.This algorithm can reject ARP spoofing,achieve the goals of maintaining network security.
