Expanding Bayes algorithm in network security model
Wenjun Liu · Jisuanji gongcheng yu sheji · 2004
Although various gateway and intrusion detection system have been designed to protect system security, they work with a hidden trouble on the imperfectness of gateway and the error diagnosis of intrusion detection system. The traditional Bayes algorithm in the intrusion detection system is improved, and the absolute coordinate is used to replace the relative coordinate, so it is easy to see the detected objeet's manner with in the scope of rules or out of the normal behavior. Besides, this model weakens the requent for independence of all the object's behavior and so it improves performance of intrusion detection system and protec-tects the security of information system more effectively.
