摘要
针对工控系统层次结构构建层次化分析模型建立判断矩阵,利用模糊一致变换计算模糊判断矩阵和元素权重值。对攻击方式和防御措施建立攻防博弈模型,计算攻击收益和混合策略纳什均衡,以及攻击可能发生的概率。最后,根据信息安全风险值计算方法得到各个攻击风险值和系统设备风险值。进行了针对性防御措施和实际场景应用分析。
A hierarchical analysis model and a judgment matrix are built for industrial control system hierarchy structure.Fuzzy consistent transformation is applied to calculate the fuzzy judgment matrix and element weight value.For attacking mode and defense measures,an attack&defense game model is established to calculate the gain and loss of attack&defense,the mixed strategy nash equilibrium and the probability of attack may happen.With information security risk assessment,the risk rate of every attack and equipment are obtained.Finally,we offer some defense measures and scenarios.
