ARP欺骗实现交换式网络数据包嗅探的原理及其防范

Principle of Packet Sniff by ARP Spoof in a Switched Network and Defense Instrument

分析了共享式网络与交换式网络数据包嗅探的差别,利用ARP欺骗实现交换式网络数据包嗅探的原理与方法,并提出了应对措施。

The paper contrasts the sniffing in a shared network and the sniffing in a switched network, discusses the principle and technique of packet sniff by ARP spoof in a switched network,and introduces some defense instruments.
