Abstract

An approach to network anomaly detection is investigated, based on dynamic self-organizing maps (DSOM) and ant colony optimization (ACO) clustering. The basic idea of the method is to produce the cluster by DSOM and ACO. With the classified data instances, anomaly data clusters can be easily identified by normal cluster ratio. And then the identified cluster can be used in real data detection. In the traditional clustering-based intrusion detection algorithms, clustering using a simple distance-based metric and detection based on the centers of clusters, which generally degrade detection accuracy and efficiency. Our approach based on DSOM and ACO clustering can settle these problems effectively. The experiment results show that our approach can detect unknown intrusions efficiently in the real network connections.
