随着网络应用的发展,网络安全评估已成为网络安全研究的一个重要课题。为了克服传统网络安全评估模型的不足,文章提出了基于灰色综合关联分析的网络安全综合评估模型。该模型将灰色关联分析法与层次分析法有机结合,首先通过德尔菲法建立评估指标体系,然后采用层次分析法确定各被评因素的权重,最后计算灰色关联度对网络安全进行评估。利用该方法对某高校网络进行仿真实验,结果表明,该方法评估结果准确,是一种高效、准确和实用的网络安全评估方法。
With the development of network applications, network security assessment has become an important issue in network security research. In order to overcome the deficiency of the traditional network security assessment model, this paper presents a comprehensive evaluation model of network security based on gray comprehensive association analysis. The model combines gray relational analysis and analytic hierarchy process. Firstly, the evaluation index system is established by Delphi method. Then the analytic hierarchy process is used to determine the weight of each factor. Finally, the gray relational degree is calculated to evaluate the network security. Using this method to simulate a university network, the results show that the method is accurate, and it is an efficient, accurate and practical method for network security assessment.
