云计算环境下的电力系统动态风险评估方法研究
Study on dynamic risk assessment method of electric power system in cloud computing environment
摘要
Abstract
The information system risk assessment is used to assess the asset threat,weakness and impact of information system,and risk possibility of the three items. In order to dynamically evaluate the safety of the electric power system in cloud computing environment,and on the basis of hidden Markov model,the available static risk assessment algorithm was improved by combining the influence of entity behavior on system risk. The threat and vulnerability of system assets are analyzed,and an improved risk calculation method is given. The theoretical analysis and experimental results show that the improved method can enhance the reliability and timeliness of the assessment results.关键词
