摘　　要：风险评估是评价网络信息系统安全的有效措施之一,基于免疫网络安全风险评估较好的动态实时性,依据现有标准风险评估方程,设计了基于免疫机理的网络安全风险评估模型,提出了一种基于粗糙集的网络风险指标权重计算方法。实现层次化分析与动态评估,在保障动态实时性的同时,又能整体不孤立的对整个网络状况做出判断,增强了模型的健壮性。仿真实验结果表明了该模型的正确性和方法的有效性。Risk assessment is one of the effective measures that evaluate the security status of network information system, on the basis of dynamic real-time of immune-based network security risk assessment, according to the existing standard risk assessment equations, a new model of immune-based risk assessment for network security is designed, and a method based on rough set theory for compute the index-weight of network risk is mentioned. Combining the use of hierarchical analysis model and the dynamic analysis of the immunity system, we can response to network risks instantly, and at the same time provide a whole but not isolated way to judge the entire network conditions and enhance the robustness of the model.
