摘要
为了实施信息系统的风险度量,首先基于信息流的资源分布规律,参考风险评估要素改进模型,得到具有体系性和完整性的风险分布;在获取风险分布后,基于资源保护角度,考虑安全保护等级,运用层次分析法、多级模糊综合评判、函数级数展开、F-统计量等方法和工具对资源的安全属性所面临的风险进行量化,给出系统的风险量化指标体系,重点考虑风险之间的相关性,构建相关性准则,并得到其计算量为o(Si)。
In order to carry out the risk quantification for the information system, the risk distribution was proposed based on resources distribution of information system, and the improvement of elements relationship model for risk assessment. In quantifying risks, Analytic Hierarchy Process （AHP）, Fuzzy Comprehensive Evaluation （FCE）, Fstatistic and Least Square Estimation （LSE） was applied to get hierarchy of risk factors. The criteria of relativity and formulated relativity functions were established.
