网络入侵检测系统的研究

Study on Intrusion Detecting System (IDS)

介绍了网络入侵的基本概念，提出了网络入侵检测系统的基本任务，给出了一个通用的网络入侵检测系统的结构模型。对目前入侵检测系统作了分类，分析了网络入侵检测技术，指出入侵检测系统在网络安全中的作用，同时对网络入侵检测系统（ＮＩＤＳ）的发展作了展望。

This paper begins with the concept of net intrusion, discusses the basic demand to the Intrusion Detecting System (IDS), and summarizes a kind of model of the NIDS. The paper also gives out the class of the IDS, analyses the technique of the network intrusion de-tecting in detail, and discusses the role of IDS in network security. The future development of IDS is also discussed in the paper.
