A novel approach to network vulnerabilities quantitative evaluation based on Mamdani-Style fuzzy logic

It is a linguistic issue to evaluate the network vulnerabilities quantitatively in network security management. It is often claimed to evaluate the vulnerabilities properly and effectively. However, detailed analysis and evaluation based on fuzzy logic, which can deal with the linguistic problems well, is very rare. In this paper, a novel approach, based on Mamdani-Style fuzzy logic, is presented. This method considers the network vulnerabilitiespsila impact, possibility of being exploited, and the importance of the environmental assets.It involves the fuzzification of the input, rule evaluation, aggregation and defuzzification.And the simulation test shows that this method can evaluate the network vulnerabilities effectively and properly.
