Vulnerability assessment of security systems based on risk entropy and Neyman-Pearson criterion

摘要

In this paper, security systems deployed in different places in a guard zone are considered as a security network. For a security network, its vulnerability is an important metric to judge whether its protection effectiveness is good or not. How to evaluate the vulnerability? The protection model of security systems via risk entropy and Neyman-Pearson criterion is put forward. According to the model, we propose methods to determine the most vulnerable path of a security network. The protection probability of the most vulnerable path is used to assess the vulnerability of a security network.
