Abstract

A security network is considered as a diagram of security systems deployed in different places in a guard zone. For a security network, its risk is an important metric to judge whether its protection effectiveness is good or not. How to evaluate the risk of a security network In this paper, the protection coverage area of a security system is considered. We put forward the protection model that can be used to determine the protection coverage of a security system and define the protection probability on a grid-modeled field. According to the Shannon Information Theory, we propose the risk entropy, which can be used to quantitatively evaluate the risk of arbitrary position in an area. We use Dijkstra's shortest path algorithm to find the weakest protection path. The protection probability on the weakest protection path is considered as the risk measure.
