The Universities Work Network invasion Examination System Grinds

With the development of computer and network technology, more and more network including campus network intruded by hackers. Security expert found that only use protection technology to build a security system is not enough. The Intrusion Detection System (IDS) has become a new method for network security, which apart from tradition security protect technology, such as firewall and data encryption. This paper, firstly, introduce the intrusion detection principle and the relative work in the aspect of distributed intrusion detection. On the basis of analyzing the existing model of distributed intrusion detection system, this paper brings forward the model framework of an agent-based intrusion detection system. The distributed model composed of an agent console and several agents, integrating the network-based and host-based intrusion detection methods and using the agent technology to detect the intrusion in the distributed environment. It can detect intrusion effectively and is extensible for adding new intrusion detection agents or new intrusion models. system is not enough.
