摘　　要：作为交换式局域网重要协议之一,地址解析协议(AddressResolutionProtocol,ARP)对局域网的正常运行具有十分重要的作用。ARP诞生之初,局域网并未得到广泛应用,ARP设置的运行机制在现有的局域网环境下存在安全隐患。基于ARP的原理,对ARP存在的典型安全漏洞进行了分析,并对局域网环境中通过利用ARP存在的漏洞进行局域网攻击的一般流程进行了介绍,提出了主机主动防御和网络安全设备防御两种典型防范方法。As one of the important protocols for switched LANs,the address resolution protocol(ARP)plays a crucial role in the normal operation of LANs.At the beginning of the birth of the ARP,LANs were not widely used,and the operating mechanism set by the ARP has security risks in the existing LAN environment.Based on the principles of the ARP,this article analyzes the typical security vulnerabilities of the ARP,introduces the general process of using the vulnerabilities of the ARP to carry out LAN attacks in the LAN environment,and proposes two typical prevention methods:host active defense and network security device defense.
