局域网中的DHCP攻击防范策略分析

Analysis of DHCP Attack Prevention Strategies in Local Area Networks

阐述动态主机配置协议(Dynamic Host Configuration Protocol,DHCP)是在局域网中普遍使用的协议,对提高网络配置效率,减轻网络管理员管理工作量具有十分重要的作用。基于DHCP协议的原理,分析在局域网环境中通过利用DHCP协议存在的漏洞进行攻击的一般流程,并针对不同攻击方法提出应对措施。

This paper describes that Dynamic Host Configuration Protocol(DHCP)is a widely used protocol in local area networks,which plays a crucial role in improving network configuration efficiency and reducing the workload of network administrators.Based on the principle of DHCP protocol,it analyzes the general process of attacking through exploiting vulnerabilities in the DHCP protocol in a local area network environment,and proposes countermeasures for different attack methods.
