Research on Multidimensional System Security Assessment Based on AHP and Gray Correlation

Abstract

Aiming at the problems of the network security evaluation indexes, which are one-sided and difficult to be strictly quantified, this paper proposes the multidimensional system security evaluation method based on AHP and grey relational analysis. Under the guidance of the construction principle of system security evaluation model, this paper puts the source of factors affecting network security as the criterion of dimension Division, and constructs a multidimensional system security evaluation model for environmental security, network security and vulnerability security. On this basis, this paper combines AHP and grey relational analysis theory, and evaluate system security comprehensively and quantitatively. The multidimensional system security evaluation method based on AHP and grey relational analysis can consider the relationship between qualitative and quantitative factors in system security, and it is highly logical and flexible. This method also can effectively solve the problem that system security is difficult to evaluate objectively and quantitatively, and the system security evaluation can be pushed from a simple rough comparison to a comprehensive quantitative calculation stage.
