在本文中，我们报告了网络攻击对复杂工业系统弹性的影响建模的最新结果。我们使用一个混合模型的系统研究，在这两个意外的网络故障和恶意行为的Adjunct建模随机，而故障和攻击的后果建模详细使用确定性模型。这种建模方法在一个复杂的案例研究中得到了证明-参考电力传输网络（NORDIC 32），该网络通过用于符合国际标准IEC 61850的监测，保护和控制的计算机和通信网络的详细模型进行了增强。我们研究了不同场景下建模系统的弹性：（i）基线场景，其中建模系统在没有网络攻击的情况下意外故障的情况下运行;（ii）几种不同的网络攻击场景。我们讨论的建模方法，研究结果的有用性，并概述了进一步工作的方向。
In this paper we report recent results on modelling the impact of cyber-attacks on the resilience of complex industrial systems. We use a hybrid model of the system under study, in which both accidental network failures and the malicious behaviour of an Adversary are modelled stochastically, while the consequences of failures and attacks are modelled in detail using deterministic models. This modelling approach is demonstrated on a complex case study - a reference power transmission network (NORDIC 32), enhanced with a detailed model of the computer and communication network used for monitoring, protection and control compliant with the international standard IEC 61850. We studied the resilience of the modelled system under different scenarios: (i) a base-line scenario in which the modelled system operates in the presence of accidental failures without cyber-attacks; (ii) several different scenarios of cyberattacks. We discuss the usefulness of the modelling approach, of the findings, and outline directions for further work.
