Abstract: The article designs an intrusion detection system model based on data mining technique.The model based on the Snort intrusion detection system utilizes data mining technique to add clustering analysis module,anomaly detection engine and correlation analyzer.The system can not only effectively detect new invasion,but also promote detective speed.So it can solve a problem that general network detect system does nothing to new invasion as well as meet the real-time demand.

Key words: intrusion detection, data mining, Snort
