摘要

中文摘要: 为了得到信息系统安全措施有效性的评估模型，研究不同的安全措施对抗某一风险的相关性，在假设不同安全措施对抗某一风险的有效性存在（抽象）函数关系的前提下，通过归一化处理展开成级数，引进所有可能的数学意义上的相关性表示，然后根据Gram-Schmidt正交化、F-统计量等这些数学工具结合回归分析的方法逐步剔除冗余相关性，进而得到最终的安全措施有效性评估模型，这比传统的线性评估模型具有更高的精度。

Abstract

Abstract:To formulate a model that can evaluate the effectiveness of information system safety measurements

the relativity between safety measures counting certain risks (1∶n or m∶1) was studied.Supposing that the effectiveness of different safety measures has abstract function relation

the function was extended into power series by normalization

introduced all possible mathematical relativity

and eliminated redundant relativity by F-statistic and Gram-Schmidt orthography algorithm.By regression analysis

we get the high precision evaluation model than the line evalution model.
