由于ARP协议本身的漏洞,ARP攻击特别频繁。目前解决ARP攻击的思路多集中在客户端安装ARP防火墙或在网络中部署安全设备。通过分析ARP攻击的基本原理和交换机功能特性,本文列举了七种基于智能交换机防御ARP攻击的方案。网络管理员结合网络环境合理选用方案,能提高网络管理的便捷性和网络的安全性。
ARP attacks are particularly frequent due to vulnerabilities in the ARP protocol itself. At present, the ideas for solving ARP attacks mostly focus on client installation of ARP firewall or deployment of security devices in the network. By analyzing the basic principles of ARP attacks and switch features, this article lists seven solutions based on intelligent switch defense ARP attacks. Network administrators combined with the network environment reasonable selection program, can improve the convenience of network management and network security.
