The Industrial Internet Security Situation Assessment Method Based on AHP-CRITIC Hybrid Weighting

The assessment index system for industrial Internet network security relies too heavily on expert knowledge and overlooks the impact of objective factors on situation assessment. This paper addresses this issue by focusing on the characteristics of industrial networks, specifically the impact of asset vulnerabilities and alarm events on network situation. A comprehensive weighted hierarchical industrial Internet situation assessment method is proposed. The final comprehensive weight is obtained using the least square method, combined with the supervisor weight calculated by the analytic hierarchy process and the objective weight calculated by the CRITIC method. Finally, a network security experiment center is used to carry out situation assessment, and the evaluation value is calculated. Experimental results demonstrate that this method provides a more objective and accurate approach to situation assessment.
