Modeling facility protection for numerical vulnerability assessment

Numerical vulnerability assessment provides calculations of possible facility attacking paths of the adversary. Path analysis is used to recommend facility modification or to add security elements to the most vulnerable path in order to reduce the vulnerability of the protected facility. For the implementation of the numerical vulnerability assessment it is necessary to develop a mathematical model of the protected facility. This paper presents an object based modeling approach that enables configuring the protected facility, placing the sensors, setting the blocking elements to delay the intruder, the use of burglary tools, modeling the security personnel activity, etc.
