摘　　要：研究网络安全准确评估问题,由于非法入侵使网络存在安全隐患,为最大限度降低网络安全带来的损失,在分析网络安全态势影响因素的基础上,提出一种模糊层次分析的网络安全态势评估模型。先构建构建网络安全指标体系,采用层次分析法计算各评估指标权重,并采用模糊方法建立网络安全态势一致性判断矩,从而实现对网络安全态势进行综合评估。仿真结果表明,模糊层次分析法提高了网络安全态势评估的准确率,评估结果更加客观,是一种有效的网络安全态势评估方法。The networks are facing many security hidden dangers,and the network information security is facing huge risks and security threats.To reduce the network security loss,based on the analysis of the factors influencing network security situation,the network security situation assessment model was proposed based on fuzzy analytic hierarchy process method.The analytic hierarchy process was used to calculate the evaluation index weights,and the network security posture fuzzy hierarchical analysis evaluation model of network security situation was put forward.Research result shows that the evaluation model has very good scientific and practical rationality,and can improve the network security situation of present situation assessment.
