摘要
针对当前网络系统安全风险评估错误大、结果可信度低等缺陷,设计了基于组合优化理论的网络系统安全风险评估方法。首先分别采集网络系统安全风险评估数据,其次分别采用3种方法对网络系统安全风险进行评估,然后根据组合优化理论,采用证据理论确定3种方法的网络系统安全风险评估权值,最后根据权值对3种方法的网络系统安全风险评估结果进行组合,输出最终网络系统安全风险评估值,并采用仿真实验分析了网络系统安全风险评估性能,结果表明,这种方法的网络系统安全风险评估正确率要高于对比方法,具有更好的实际应用价值。
Aiming at the defects of current network system security risk assessment,such as large errors and low credibility,a network system security risk assessment method based on combinatorial optimization theory is designed.Firstly,the network system security risk assessment data are collected,and then three methods are used to evaluate the network system security risk.Then,according to the combination optimization theory and evidence theory,the network system security risk assessment weights of the three methods are determined.Finally,the network system security risk assessment results of the three methods are combined according to the weight,and the final network system security is output.The results show that the accuracy of the network system security risk assessment is higher than that of the comparison method,and has better practical application value.
