Anomaly-Based Unsupervised Intrusion Detection

At Black Hat Europe we met Stefano Zanero who talked about anomaly-based unsupervised intrusion detection. In this video he provides an overview of his research into the subject by illustrating how he worked trying to find ways to detect intruders without relying on signatures. To get more information about the subject take a look at his whitepaper and his presentation from Black Hat Europe 2007.
