A Novel IDS Model and the Arithmetic to Get the Detection

A new intrusion detection model that based on the theory of artificial immune system is introduced in this article. It researches emphases on the arithmetic of how to get the detector that included in the negative selection arithmetic. It also puts forward a new arithmetic of how to get the detector and then analyses the arithmetic. The result indicate that, the arithmetic model can do the effective identify variation between the unknown intrusion action and the known one.
