Physical security management system
First Claim
1. A security system for protecting a physical installation, the security system comprising:
- an access controller for controlling access to the physical installation comprising access control rules;
a plurality of physical sensors in communication with the controller, wherein the plurality of physical sensors sense physical threats to the physical installation;
a sensor report aggregator connected to the plurality of sensors and in communication with the access controller; and
a security reference model connected to the sensor report aggregator, wherein the security reference model contains information about the protected physical installation including information about the protected physical installation'"'"'s security goals;
wherein the sensor report aggregator outputs hypotheses descriptive of a threat situation based on combined reports from the plurality of sensors to the access controller.

Abstract
A physical security system having a plurality of sensors and a sensor report aggregator. The sensors may detect a large number of physical activities. The aggregator may cluster a large number of detected reports to a small number of sets of reports. The sets of reports may be reduced to hypotheses. From the hypotheses, the aggregator may develop hypotheses about the physical environment which the sensors are monitoring in view of a security reference model. The security reference model may include, but not be limited to, facility models, physical security models, and/or attack models. The hypotheses may have probabilities assigned to them according to their certitude of likelihood and severity of danger.
