An Intrusion Detection System Model Based on Immune Principle and Performance Analysis

1　Introduction　 With the rapid development of Internet, network securityhas gotten the increasing focus of government, enterprise,even the individuals. But with the continuously spread ofnetwork application, attacks and destroys aiming at it in crease steadily also. Intrusion detection is a kind of networksecurity technique to detect any damage or attempt to tamperthe secrecy, integrality and usability of system. IntrusionDetection System (IDS) is an automated system for t…

An Intrusion Detection System Model Based on Immune Principle and Performance Analysis

The study of security in computer networks is a key issue,which is a rapidly growing area of interest because of its importance.Main network security problems are analyzed in this paper above all,which currently are confronted with network systems and existing works in intrusion detection.And then an intrusion detection system model based on Immune Principle(IPIDS)is presented.Meanwhile,it expatiates detailed implementation of the methods how to reduce the high false positive and negative alarms of the traditional Intrusion Detection System(IDS).At last a simple simulation is performed on this model just using string match algorithm as binding mechanism.The simulation results indicate that the model can detect malicious activity effectively,and consequently the security and steadiness of the whole network system are improved also.
