Abstract

An intrusion detection system and method for detecting unauthorized or malicious use of network resources includes an intrusion detection analysis engine that instanciates one or more analysis objects to detect signatures associated with attacks on network vulnerabilities. As new network vulnerabilities are identified, new analysis objects can be dynamically interfaced on a runtime basis with the intrusion detection analysis engine to detect signatures associated with the new network vulnerabilities. A signature application programming interface supports communication between the intrusion detection analysis engine and the analysis objects. When the instance of an analysis object indicates that an associated signature exists in network data, the intrusion detection analysis engine can provide an alarm.
