【摘要】：研究多源网络事件的安全评估准确性问题,针对利用网络中众多安全设备组成的防御体系得到的多源安全评估数据,计算评估参数完成安全事件评估时,传统的方法将多源安全数据进行简单加权平均得到评估参数,造成网络事件安全评估准确率不高的问题。提出基于AHP权值计算的网络安全评估方法,通过构建三层递阶层次模型,依据准则层的计算原则,进行多源事件权值比重的层次化计算,并根据权重计算得到评估参数,避免了传统简单加权平均法计算评估参数导致的评估不准确的问题。实验表明,改进方法能够根据计算机网络的安全原则计算设定多源事件的权值,准确完成安全事件的评估,保证了网络事件的安全评估准确性。
[Abstract]:This paper studies the accuracy of security assessment of multi-source network events. In view of the multi-source security evaluation data obtained from the defense system composed of many security devices in the network, the evaluation parameters are calculated to complete the security event assessment.The traditional method simply weighted the multi-source security data to get the evaluation parameters, which caused the problem that the accuracy of network event security evaluation is not high.This paper presents a network security evaluation method based on AHP weight calculation. By constructing a three-level hierarchical model, according to the calculation principle of criterion layer, the hierarchical calculation of weight weight of multi-source events is carried out, and the evaluation parameters are obtained according to the weight calculation.It avoids the problem of inaccurate evaluation caused by the traditional simple weighted average method.Experiments show that the improved method can calculate and set the weights of multi-source events according to the security principle of computer network, complete the evaluation of security events accurately, and ensure the accuracy of security evaluation of network events.
