Effectiveness Evaluation of Security System Based on Entropy Theory
With the security industry developing rapidly and the number of security systems increasing continuously in recent years, security systems provide a positive effect on society security in China, but many of them became vulnerable or even useless because of the problem of irrational allocation of resources. In order to evaluate security system efficiency to avoid these problems, we present the concept of efficiency entropy based on the Shannon information theory, and build an Efficiency Entropy Evaluation Model which can be used to evaluate the efficiency of the security system quantitatively. It represents security system effectiveness in single node layer and the entire security network layers. So the effectiveness of the whole security system is calculated quantitatively.
