摘　　要：研究网络安全问题,网络安全评价是一项复杂的系统工程。由于各种不正常信息入侵,病毒的干扰,影响着网络的安全。评价指标体系的建立和权重的确定是科学合理确保网络安全的手段。传统的定量评价方法无法准确测量,导致评价结果不准确,误差比较大。为了提高网络安全评价准确率,结合网络评价实际情况,提出一种层次分析法的网络安全综合评价模型。首先利用德尔菲法构建网络安全评价指标体系;然后利用层次分析法确定各指标的权重,并对网络安全进行评价;最后以具体实例对评价模型进行仿真。结果表明,层次分析法评价模型能够客观对网络安全状况进行评价,提高网络安全评价准确率,为网络安全提供了一种新的评价方法。Researching on network security.Network security evaluation is a complicated system.According to relevant standards,evaluation of network security is all-round,multi-level process,which is very complicated.The keystone of comprehensive evaluation of network security is to build the index system and calculation the index weight.In accordance with the actual situation of network security,the model of network security evaluation is built based on analytic hierarchy process.Firstly,on the basis of analysis of various factors and measures of network security,the paper used the Delphi method to construct the network security comprehensive evaluation index system.Secondly,the specific weight of each index was worked out by AHP,and the network security wan evaluated.Finally,the specific examples were used to evaluate and validate the model.Research results showed that this model can evaluate the network security rating situation objectively and effectively,which is an ideal model for evaluating the network security.
