Research And Implement Of Network Based Intrusion Detection System

The intrusion detection technology is complementarities for traditional security protecting technology, such as firewalls. It can identify and response to malice activities by monitoring the host system or the Internet. It also can stop intrusion activities with the linkage of other security technology. The research and development of IDS has become the important subject about network security.In the first, the text introduces the background of subject bringed forward. In chapter 2 we primarily introduce the phylogeny, conception, category, actuality, and the developing direction of intrusion detection system. In chapter 3 on design and implement of network based intrusion detection system, we put forward the systematic framework of the network based intrusion detection system, and give concrete design and implement of every part. In chapter 4 we introduce the network based intrusion detection system, its framework and the fuction of every part.Finally we give the next development target and summarize the text.
