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。The safety evaluation accuracy of the multi-source network events was researched.A new network security evaluation method based on the AHP weights calculation was put forward.By constructing a three-layer hierarchical time model and relying on the calculation principle of the rule layer,the multiple source event weights were processed by hierarchical structure calculation.And the evaluation parameters were achieved according to the calculated weights,avoiding the inaccurate evaluation led by calculating the evaluation parameters with the traditional simple weighted average method.It is shown that the proposed method can calculate and set the weights of multisource events according to the computer network security principle,finish the evaluation of security events precisely,and ensure the accuracy of the network events safety evaluation.
