Research and Design of Intrusion Detection System in Computer Network

This paper combines the design of the intrusion detection system based on host and based on network.According to various intrusion detection technology, the paper focus on the mechanism of integration, cooperation, selective of intrusion detection system, so as to achieve the optimization method is introduced to intrusion detection system, put forward a kind of intrusion detection system based on a variety of detection methods and technology, and establish the overall structure of integration, cooperative, selective, so as to achieve the system optimization, and make the network system security really get better effect.
