MAC地址攻击及其防御机制的研究与实现

Research and implementation of MAC address attack and its defense mechanism

MAC地址攻击是一种数据链路层攻击,攻击者通过伪造MAC地址来欺骗交换机,从而达到窃取网络数据的目的。而端口安全是一种基于MAC地址对网络接入进行控制的安全机制,它将接口学习到的动态MAC地址转换为安全MAC地址。通过对MAC地址欺骗攻击和CAM地址表溢出攻击原理的研究,提出了通过端口安全技术机制来进行防御,并详细实现了防御MAC地址攻击的全过程。

MAC address attack is a data link layer attack.The attacker cheats the switch by forging MAC address to steal network data.Port security is a security mechanism that controls network access based on MAC addresses,which converts dynamic MAC addresses learned by interfaces into secure MAC addresses.Research on the principles of MAC address spoofing attacks and CAM address table overflow attacks,proposes defense through port security technology mechanisms,and implements the entire process of defending against MAC address attacks in detail.
