摘　　要：针对网络安全态势评估指标体系的不完善和难以选取及构建等问题,以相关标准和规范为基础,从系统安全机制出发,按照既定原则,提出了基于态势熵的网络安全态势评估指标体系的构建方法,并给出了网络可用性方面的态势评估指标值的计算方法。实验表明,态势熵值的变化与所反映的网络安全态势是一致的,说明该指标体系的构建具有一定的科学性,为网络安全态势评估提供了一种新的数据解决途径。For solving the problem of network security situation assessment index system imperfect and other difficult issues such as selection and construction,on the basic of relevant standards and norms,and starting from the system security mechanism,a index system construction method of assessment for network security based on situation entropy is proposed,and the assessment index value calculation on the network availability is given.Experiments show that the change of situation entropy and the reflected network security situation is the same,also shows the index system has some scientific,and provides a new data solution for network security situation assessment.
