An ISM-based Analysis Method on the Influencing Factors of Network Security Situation (NSS)

Abstract

For the accuracy of network security management, an ISM-based analysis method on the influencing factors of network security situation (NSS) is proposed. The 17 factors of NSS were constructed first, the ISM of NSS influencing factors was established, and Matlab2019 was used for simulation. The results showed that the offensive and defensive game factors, such as attack method, attack tool, attack path, and defense strategy, are the direct influencing factors of NSS; the internal environmental factors such as operating system, application service, network bandwidth, network security device, user security awareness, and network topology are the necessary influencing factors; the external environmental factors such as legal environment, institutional environment, technical environment and business importance (economic environment) are the indirect influencing factors; the vulnerability factors such as asset value, vulnerability and open port are the fundamental influencing factors. The corresponding advice for management was put forward at the end of the paper.
