Electric power information system security risk assessment based on fuzzy rating multilevel analysis

Based on large-scale information system, the system model of active defense system, the information system risk identification and analysis of the deficiencies and shortcomings, this paper describes a multi-level analysis based on fuzzy evaluation model of the risk. By analyzing the characteristics of the information system to analysis the risk and risk factor in the information system, this paper adopts the Multi-level analysis technology and fuzzy evaluation method to establish the risk assessment of risk and calculation model.
