Traditional data mining techologies used in data mining need to build intrusion detection model in labled data set. The process to lable data set is all by hands, and if the lables have some errors, the efficiency of the intrusion detection system will be affected. Unsupervised anomaly detection methods can detect the anomaly records in unlabled dataset.
