This proposal addresses directly several of the major security implementation issues facing large enterprises and service providers. Specifically it seeks to create an agent-oriented layered architecture to enable the delivery of multiple pattern-based and behaviour-based scanning and filtering functions at very high speeds. The major technical objectives are to provide a framework for the concurrent operation of reactive and proactive security algorithms, to deliver algorithmic enhancements for pattern recognition and behaviour-based detection schemes, as well as enhanced and highly correlated rule sets for more efficient alarm management and root-cause analysis.
