Abstract: Enterprise threat assessment and management provides both physical and logical security. Physical access control systems are configured to identify physical events in the physical domain, and logical access control systems are configured to identify logical events in the logical domain. Connectors establish uninterrupted coupling to the physical and logical access control systems. Event middleware is configured to selectively subscribe only to those events that correspond to defined policies. The policies define a correlation of the physical and logical events, actions are initiated depending upon the correlated physical and logical events defined by the policies.
