Based on natural immune theory,this research simulates natural cognition and memory mechanism to form and analyze an algorithm of constructing detector.

Based on natural immune theory, in this paper, the author simulated natural cognition and memory mechanism, and further formed a method of constructing detector.

Natural immune systems protect animals from dangerous foreign pathogens.

Research of intrusion detecto based on biological immunity;

In recent years, the intrusion detection based on biological immunity has become a key research area in network intrusion detection system.

From the viewpoint of control, the paper discusses the similarity of computer immunology and biological immunology.

In light of the system flaws arising from the transfer of disease-causing mechanisms of biological immune system into IDS,an algorithm for optimizing measure parameters based on genetic algorithm and biological immunology is designed together with a hybrid intrusion detection engine.
