  8. Detecting Intrusions • Statistical anomaly-based IDS • Uses thresholds for various types of activities • Pattern matching or signature-based IDS • Uses a set of rules to detect an attack • Content-based and context-based signatures • Cisco host-based and network-based IDS detect attacks based on signatures and anomalies
