A New NIDS Model Based on Dangerous Model Theory

The NIDS models based on immunity have many deficiencies.For these deficiencies,a new NIDS model in which the new immune recognition theory (Dangerous Model Theory) was used has been put forward in this paper.In this model,role of the self library has been changed to release Detection Agents;Immune recognition mechanism based on abnormal signals has been introduced,the rate of mis-alarm was reduced and the adaptability was advanced; A new affinity algorithm has been put forward,efficiency and veracity has been advanced depend on "key gene snippet control string".
