Research And Application Of Intrusion Detection System

With the attack means complicated and diversified, the traditional intrusion detection means can't meet the need of network security, and the intelligent intrusion detection system has already become one of keys in the realm for the research of intrusion detection and even in the whole field of network security. This paper uses neural network model to realize the intelligent detection in this system. At the same time for improving the speed of study of network, the rough set that can reduce the attribute from a great deal of data is used. Finally, a new intelligent intrusion detection system-R_NNIDS is designed based on these theories. The result of experiment testing this model shows that this system can complete the basal mission, so it have certain practicability; and this system can find new rules from pockets, so it have certain intelligence.
