About distributed intrusion Detection System's research

With the risk factor of network security continuously improving, firewalls, which once as a means of the most important safety precautions, can no longer satisfy people's demand for network security. As a complement of the firewall, Distributed Intrusion Detection System can effectively improve the security. This article describes the framework, the structure, the Working principle, the functional structure and the development status quo, the development trend and the algorithm design of Distributed Intrusion Detection System, analyzes the data collection module operation of Distributed Intrusion Detection System. As Distributed Intrusion Detection System can prevent internal attacks, external attacks and disoperation, it plays a crucial role in the network security protection.
