 Risk assessment of security systems based on entropy theory and the Neyman–Pearson criterionHaitao Lv, Chao Yin, Zongmin Cui, Qin Zhan and Hongbo Zhou Reliability Engineering and System Safety, 2015, vol. 142, issue C, 68-77 Abstract: For a security system, the risk assessment is an important method to verdict whether its protection effectiveness is good or not. In this paper, a security system is regarded abstractly as a network by the name of a security network. A security network is made up of security nodes that are abstract functional units with the ability of detecting, delaying and responding. By the use of risk entropy and the Neyman–Pearson criterion, we construct a model to computer the protection probability of any position in the area where a security network is deployed. We provide a solution to find the most vulnerable path of a security network and the protection probability on the path is considered as the risk measure. Finally, we study the effect of some parameters on the risk and the breach protection probability of a security network. Ultimately, we can gain insight about the risk assessment of a security system.
