ARP（地址解析）协议是TCP/IP 网络中常用的网络协议之一。其功能是根据主机IP 地址获取其物理地址。 然而由于协议的特点，基于ARP 的攻击也是常见的局域网攻击手段，给网络带来严重的安全隐患。本文结合ARP 协议的特 点，分析了常见的ARP 协议攻击方式，并按攻击方式的类别，给出了不同的解决策略。

ARP (Address Resolution Protocol) is one of the commonly used network protocol in TCP/IP network. Its function is to obtain the physical address based on the host IP address. However, ARP attack is also a common mean of local area network attack for the protocol characteristics, bringing serious security hidden danger to the network. According to the characteristics of ARP protocol, the ARP attack means are analyzed, and different solution strategies are given according to different kinds of attack.
