入侵检测系统

Intrusion Detection Systems

入侵检测系统 (IDS)是一种基于主动策略的网络安全系统 ,是对常用的被动策略的逻辑补偿 ,是网络安全系统中的重要组成部分。首先对IDS技术进行了分析 ,说明了入侵检测的技术原理 ,并从两个角度对IDS进行分类 ;接着讨论了系统的实现方法和现有的IDS系统 ;最后总结了这项技术 。

Intrusion Detection System(IDS) is an activity based network security system. As the logical supplement of usual passive policy, it is the important part of whole security system. This paper analyzes IDS , presents the mechanisms of IDS, and categorizes IDS from two different points of view. Then it discusses the existing IDS, at last ends with a discussion of the method and the promising future.
