A parallel cluster intrusion detection system for backbone network

In order to change the traditional intrusion detection system architecture modei by adopting some ef ficient intrusion detection techniques in an intrusion detection system (IDS) for backbone network, based on in-depth research on the key techniques of the IDS for backbone network, the design and implementation of a rule-based intrusion detection system for backbone network-BNIDS ( Backbone Network Intrusion Detection System) , are discussed with emphasis on the parallel cluster detection modei, packet capture mechanism and rule-based analysis engine. The results -of experiments indicate that the scalable BNIDS can do the real-time intrusion detection in a backbone network.
