Design and implementation of distributed collaborative intrusion detection system model

With the constant development of network application nowadays, the network security has become a hot issue. The intrusion detection is a good and active defense technology which will detect network security loopholes, make a response and promote network security in time. In this paper, a distributed collaborative intrusion detection system model will be proposed and a series of relatively complete intrusion detection algorithms and engines are also designed for the new model. In the meantime, the frames of distributed collaborative intrusion detection system and the function of every component are also provided. Through the simulation experiment, the stability, reliability and expandability of the system have been validated, and the expected results have been achieved.
