Research Of Intrusion Detection Technology Based On The Immunity Principle In The Third-level Net

With the traditional security mechanisms compared,Intrusion Detection is treatment after program,with intelligent control, real-time detection, dynamic response, easy configuration,etc. As Intrusion Detection require analytical data which record system track,it applies to almost all computer systems.However some IDS made use of several monitors distributing network to collect invading information don't carry complete meaning invade of distribute because the analysis of information still is concentrate.As a result, they doesn't have very strong haleness and goodly expand.The mass IDS doesn't adapt,distill and renew signature from signature knowledge.The text study "Intrusion detection technique based on the immunity principle",main basis:The first,model and arithmetic based on immunity mechanism have already been apply in excellent control, mode identify,trouble diagnosis,network safety.etc;The second,immune system and intrusion detection system resolve the problem described elimination of self and nonself.Main work include:The article analyzed currently intrusion detection technique the weakness of haleness, study and ability.etc.For strengthening network safety,the text study the arithmetic of prepaid detector,improve the arithmetic of detector,give matching rule.Experiment result indicate:arithmetic of detector improvemen is better than the form detector in the born detector.On this foundation, this text putting forward a model of immune intrusion detection with improvment algorithm, and make use of some work experiment terrace, argument the model feasibility application and availability defense.
