ULISSE, a network intrusion detection system
Stefano Zanero · 2008
In this paper we present a tool for network anomaly detection and network intelligence which we named ULISSE. It uses a two tier architecture with unsupervised learning algorithms to perform network intrusion and anomaly detection. ULISSE uses a combination of clustering of packet payloads and correlation of anomalies in the packet stream. We show the experiments we conducted on such architecture, we give performance results, and we compare our achievements with other comparable existing systems.
