Embodiment 1

[0046] see figure 1 , figure 2 , the present embodiment is based on the risk assessment system of fuzzy matrix analytic hierarchy process, including:

[0047] (1) The evaluation index system generation module 1 is used to generate the evaluation index system aimed at the hazard source. The evaluation index system is formulated by the expert group for evaluating the hazard source, and it includes a target layer, a criterion layer and an index layer. The target The layer is defined as the hazard to be evaluated. The criterion layer includes three parent indicators, the probability of the hazard occurring, the degree of influence of the hazard after the hazard occurs, and the uncontrollability. Sub-index, which considers the risk reduction and control effect of the safety measures or strategies adopted by the system, and defines uncontrollability as the ability characteristic of making the strategy invalid after the hazard occurs;

Abstract

The invention discloses a risk assessment system based on a fuzzy matrix analytic hierarchy process. The system comprises an assessment index system generation module, an assessment level system generation module, an index quantification module, a index weight calculating module, a membership degree matrix construction module, a fuzzy comprehensive result calculating module and a risk assessment module, wherein the risk assessment module comprises a risk situation assessment sub-module, a risk analysis sub-module and a risk control sub-module. The risk assessment system based on the fuzzy matrix analytic hierarchy process of the invention can analyze various uncertain factors and indexes appearing in the risk assessment process by using the fuzzy matrix and the analytic hierarchy process (AHP) in the risk assessment.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a risk assessment system based on fuzzy matrix analytic hierarchy process. Background technique [0002] In related technologies, in the process of network security risk assessment, the nature and activities of many influencing factors cannot be quantitatively described by numbers, and the results cannot be judged by a single criterion, so fuzzy mathematical methods are often used for processing. American scholar L.A.Zadeth first proposed the concept of fuzzy sets in 1965 to model fuzzy behaviors and activities. Fuzzy mathematics transfers from the basis of binary logic to continuous logic, turns absolute "yes" and "no" into something more flexible, and uses strict mathematical methods to deal with fuzzy phenomena. [0003] In addition, Analytic Hierarchy Process (AHP) is also commonly used. It is a simple, flexible and practical multi-criteria decision-making method pr...
