The paper proposes a IDS that is based on HGA and Data mining. In this model, an improved clustering algorithm is introduced to classify the normal/abnormal behaviour library from behaviour records on the network and in the system. Then it takes the HGA and data mining as a basis to dig out the the invasion rules and put them into the rule base. Finally, Hybrid Detection Module is proposed to detect the intrusion system. The experiment shows that with a high adaptability, the model has enabled to detect unknown intrusion, improve the detection rate and reduce the false detection rate, thus to protect the computer systems from exotic intrusion.
