基于证据推理算法的网络安全评估

Network Security Assessment Based on Evidential Reasoning Algorithm

针对目前网络安全评估方法在同时处理各种类型信息时精度不高等问题,提出了一种新的基于证据推理算法的网络安全评估方法.首先选取指标建立多层次的网络安全评估框架.其次,通过专家知识确定各指标的权重、评估等级和参考值,并以证据推理算法融合出来的安全态势评估值为基础,确定最终网络安全评估等级.最后,通过实验验证了该方法可以得出一个合理的评估结果,具有可行性和有效性.

Aiming at the problem that the accuracy of current network security assessment methods is not high when processing various types of information at the same time,a new network security assessment method based on evidential reasoning algorithm is proposed.Firstly,a multi-level network security evaluation framework is established by selecting indicators.Secondly,the weight,evaluation level and reference value of each indicator are determined by expert knowledge,and the final network security evaluation level is determined based on the security situation evaluation value fused by evidential reasoning algorithm.Finally,the experiment verifies that the method can get a reasonable evaluation result,which is feasible and effective.
