针对网络安全评估存在的不确定性,提出了一种新的基于区间层次分析法的网络安全评估方法.首先建立了多层次的网络安全评估指标体系,然后利用区间层次分析法确定了网络安全评估指标的区间数权重.在此基础上,结合区间数理论建立了基于区间层次分析法的网络安全评估模型.最后结合评估实例对某公司办公自动化网络进行了安全评估,验证了方法的可行性和有效性. Aiming at the uncertainty of network security assessment, a new method of network security assessment based on interval analytic hierarchy process is proposed.Firstly, a multi-level network security assessment index system is established, and then the interval network analytic hierarchy process Index based on the number of interval weights.On this basis, combined with the interval number theory to establish a network security assessment model based on interval analytic hierarchy process.At the end of the evaluation example of a company office automation network security assessment, verify the feasibility of the method and Effectiveness.
