Abstract:

The authors provided a comprehensive survey of anomaly detection systems used in the recent years. Intrusion detection was divided into 3 kinds based on technologies used. They are statistical anomaly detection, machine learning based anomaly detection and data mining based anomaly detection. The authors described the various features of anomaly detection technologies in details, represented the algorithms used in the current Anomaly Intrusion Detection Systems, the implements of the algorithms, and also compared the effects of various detection algorithms through the experiment.

Key words: anomaly detection, machine learning, statistical anomaly detection, data mining
