A Review of Anomaly based Intrusion Detection Systems

A Review of Anomaly based Intrusion Detection Systems

Abstract— With the advent of anomaly-based intrusion detection systems, many approaches and techniques have been developed to track novel attacks on the systems. High detection rate of 98% at a low alarm rate of 1% can be achieved by using these techniques. Though anomaly-based approaches are efficient, signature-based detection is preferred for mainstream implementation of intrusion detection systems. As a variety of anomaly detection techniques were suggested, it is difficult to compare the strengths, weaknesses of these methods. The reason why industries don’t favor the anomaly-based intrusion detection methods can be well understood by validating the efficiencies of the all the methods. To investigate this issue < Final Year Projects 2016 > problem, the current state of the experiment practice in the field of anomaly-based intrusion detection is reviewed and survey recent studies in this.
