Risk Assessment of Network Security Based on Non-Optimum Characteristics Analysis

Abstract

Abstract-This paper discusses in detail the theory of nonoptimum analysis on network systems. It points out that the main problem of exploring indefinite networks' optimum lies in the lack of non-optimum analysis on the network system. The paper establishes the syndrome and empirical analysis based on the non-optimum category of the network security. At the same time, it also puts forward the non-optimum measurement of the network security along with non-optimum tracing and selforganization of the network systems. The formation of nonoptimum network serves as the basis for existence of optimum network. Besides, the level of network security can be measured from the non-optimum characteristics analysis of network systems. By summing the practice, this paper has also come at the minimum non-optimum principle of the network security optimization, established the relationship between risk and nonoptimum, and put forward evaluation method about trust degree of network security. Finally, according to the previous practice of network security risk management, a kind of network security optimization has been developed to approach the relationship of non-optimum and risk.
