More Information
Summary:Disclosed is a system for correlating intrusion events using attack graph distances. The system includes an attack graph generator, an exploit distance calculator, an intrusion detector, an event report/exploit associator, an event graph creator, an event graph distance calculator, a correlation value calculator, and a coordinated attack analyzer. An attack graph is constructed for exploits and conditions in a network. The exploit distance calculator determines exploit distances for exploit pair(s). The intrusion detector generates event. Events are associated with exploits. Event graph distances are calculated. Correlation values are calculated for event pair(s) using event graph distances. The correlation values are analyzed using a correlation threshold to detect coordinated attacks.
