影响网络安全性的因素辨识、评价与分析

Factors Recognition、Evaluation and Analysis on Influencing Network Security

本文采用DEMATEL方法对影响网络安全性的所有可能因素进行关联分析,系统分析了各影响因素的综合影响指数,按照影响程度辨识主要影响因素,从而给出所有因素的影响程度的排序,按照中心度的大小,选取最重要的五个因素作为网络安全性评价的指标,通过层次分析法确定了指标权重,建立了网络安全等级的模糊综合评价模型,在此基础上提出了提高网络安全性的相关对策。

In this paper, we uses the DEMATEL method to carry on the incidence analysis on all possible factors influencing network security, By calculating the comprehensive influencing index of all factors, the major effect factors are recognized, so we can recognize their degree orders quantitatively. The five factors are chose as the index for network security evaluating according to their central degrees. The weight of the index are determined by AHP and the fuzzy comprehensive evaluation model is established. Based on the above, the corresponding strategies for the development of network security are present.
