ROOK: Multi-session Based Network Security Event Detector

We have implemented Multi-Session based Network Security Event Detector: ROOK to detect botnet activity and P2P file sharing traffic and our results show that our method is less false positives than existing network security event detectors (e.g. IDS). We proposed a network security event detection method by analyzing correlation among multiple sessions. Our method can recognize hosts behaviors by rules that describe multi-session correlations: a rule includes the order of starting sessions and information exchange between sessions. By this method, ROOK detected DNS and IRC activities of bots in the experiment.
