利用ARP协议的漏洞对网络进行攻击,是当前计算机网络所面临的的主要威胁之一。本文首先对ARP协议进行了理论分析,探究了ARP协议的工作原理和存在的漏洞,并根据漏洞进行了ARP攻击和防御的实验,提出了ARP缓存清除,MAC地址静态绑定、划分VLAN等ARP攻击防御的方法。研究结果可以用于局域网内的安全防御,同时整个实验过程还可为高校计算机网络安全教学提供教学实例。
Exploiting the ARP protocol vulnerabilities to attack the network is one of the major threats to the current computer network. This dissertation firstly analyzes the ARP protocol theoretically, explores the working principle and existing vulnerabilities of ARP protocol, and experiments ARP attacks and defenses according to vulnerabilities. ARP cache cleaning, static MAC address binding, VLAN-based ARP, Attack defense method. The research result can be used in the security defense in the LAN, and the entire experimental process can also provide teaching examples for the computer network security teaching in colleges and universities.
