Ad hoc网络的入侵检测技术

Intrusion Detection Technology in Ad Hoc Network

随着无线网络的发展和移动计算应用的快速增加,网络安全问题愈加突出.入侵检测已经从保护固定有线网络扩展到移动无线网络.作为无线移动网络众多实现方式之一的移动Ad hoc网络,由于其与有线网络存在很大差别,现有针对有线网络开发的入侵检测系统很难适用于移动Ad hoc网络.在描述入侵检测技术的相关内容基础上,提出了基于移动Ad hoc网络的多层分布式入侵检测系统模型,并重点分析了在该模型中的协议分析技术.

With the rapid development of wireless network and mobile computing, the security of network becomes more important. As one of wireless mobile network, mobile Ad hoe network has new vulnerabilities that do not exist in a fixed wired network, and is susceptible to attacks. This paper introduces some methods which used in intrusion detection system and provides a new model of system based on multi - layer integrated distributed technology, especially recommend the protocol analyzing method in this system.
