A method and system for adaptive network security using intelligent packet analysis are provided. The method comprises monitoring network data traffic. The network data traffic is analyzed to assess network information. A plurality of analysis tasks are prioritized based upon the network information. The analysis tasks are to be performed on the monitored network data traffic in order to identify attacks upon the network.

Method and system for adaptive network security using intelligent packet analysis

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.

Intrusion detection system and method having dynamically loaded signatures

A method and system for adaptive network security using network vulnerability assessment is disclosed. The method comprises directing a request onto a network. A response to the request is assessed to discover network information. A plurality of analysis tasks are prioritized based upon the network information. The plurality of analysis tasks are to be performed on monitored network data traffic in order to identify attacks upon the network.
