The system includes Policy Connectors, wherein each PC has a specific set of rules and relevant data and an event collector comprising centralized event collector software, wherein the event collector collects security events, and wherein each security event is created in the PMS-SM system using MSSMSP. Each event arises from an application. The system also includes security events which include Business Asset Monitor events. A BAM event represents user activity against a specific business asset and Security data that is queried from the various security sub-systems using the PC's and a Security policy of MSSMSP.
