ARP攻击的原理分析及防范对策研究

Research on the Principle of ARP Attack and Its Countermeasures

计算机网络的迅猛发展和普及,改变了人们的工作与生活,但同时也给人们带来了新的隐患,网络安全事件层出不穷。在目前计算机网络运行与使用中,ARP攻击成为最为常见的问题。本文结合自身实际工作经验,提出了一种新的ARP防御方案,在介绍IP地址和MAC地址的基础上,阐述了ARP协议的工作过程,剖析了ARP协议存在的弊端,分析了ARP攻击的原理。从网管中心端和用户端两个角度讨论防范ARP攻击的策略,并在网络环境中演示了这些策略防范ARP攻击的效果。

The rapid development and popularization of computer network have changed people's work and life,but also brought people new hidden troubles-endless network security events.In the current computer network operation and application,ARP attack constitutes the most common problem.The paper proposes a new ARP defense scheme based on practical experience.On the basis of introducing IP address and MAC address,this paper elaborates on the working process of ARP protocol,expounds the disadvantages of ARP,and analyzes the principle of ARP attack.This paper discusses the strategies of preventing ARP attack from both the network tube center and the user,and demonstrates these strategies in the network environment to prevent the effects of ARP attack.
