摘要： 防止非法监听和对监听者进行有效干扰是安全网关的重要环节,该文首先分析了局域网中Sniffer监听原理的实现方法,检测和干扰Sniffer的方法,然后列出远程(跨越局域网)监测Sniffer的方法,并评述这些方法的优缺点。最后提出了利用通用通信平台,结合远程控制和本地检测Sniffer的原理和方法,实现了针对广域网环境的准确定位、及时干扰的Sniffer监测系统。

Abstract: Detecting and disturbing the malicious sniffer under LANs is a crucial part of the network security management and networkinformation security. This paper introduces the principle and action of sniffer. Then it analyses some remote sniffer detection methods and discussestheir disadvantages. Finally, it puts forward a new system of remote sniffer detection across gateway by compiling the communication platform andtraditional sniffer detection methods, which can locate the targets accurately and disturb them immediately.
