A Hierarchical Network-Based Security Posture Assessment Method for Power Monitoring System

Aiming at the problem of network security posture assessment in the existing attack classification system of electric power monitoring system, this paper researches the security posture assessment method of electric power monitoring system based on hierarchical analysis network. This research analyzes the security posture of the system from the device layer and the network layer, and designs the assessment index system based on the grey clustering analysis method, and optimizes the index weights by combining with the gravitational search algorithm, and finally obtains the network security posture perception model. The model presents the overall network state through hierarchical analysis, and simulation experiments show that the proposed method can obtain accurate and detailed network security situation information.
