以配电自动化系统为研究对象,进行系统分解,对分解模块进行资产归类,并参照信息安全评估标准ISO/IEC17799:2005,分析影响各类资产信息安全的多项指标,从而构建一套多层次,多角度全面反映信息安全等级的评价指标体系。提出了基于改进的D—S证据理论和模糊层次分析法(FAHP)的配电自动化系统信息安全等级的评估方法。列举了应用实例。
Distribution automation system was researched by decomposing system into different modules and classifying decomposition modules to different sorts. According to information security assessment standard ISO/IEC 17799:2005 to analyze the indices, which affect the information security levels of each sort, to construct an assessment indices hierarch,which reflects information security risk assessment comprehensively from multi-hierarchy and multi-attribute, basing on this to do assessment. Assessment method of information security levels in DAS using FAHP and improved D-S was presented in the paper. Demonstration was given.
