Modern critical infrastructure, such as a water treatment plant, water distribution system, and power grid, are representative of Cyber Physical Systems (CPSs) in which the physical processes are monitored and controlled in real time. One source of complexity in such systems is due to the intra-system interactions and inter-dependencies. Consequently, these systems are a potential target for attackers. When one or more of these infrastructure are attacked, the connected systems may also be affected due to potential cascading effects. In this paper, we report a study to investigate the cascading effects of cyber-attacks on two interdependent critical infrastructure namely, a Secure water treatment plant (SWaT) and a Water Distribution System (WADI).

现代关键基础设施，例如水处理厂，配水系统和电网，是网络物理系统（CPS）的代表，其中实时监视和控制物理过程。这种系统中复杂性的一种来源是由于系统内部的交互作用和相互依存关系。因此，这些系统是攻击者的潜在目标。当这些基础结构中的一个或多个受到攻击时，由于潜在的级联效应，连接的系统也可能会受到影响。在本文中，我们报告了一项研究，以研究网络攻击对两个相互依赖的关键基础设施（安全水处理厂（SWaT）和水分配系统（WADI））的级联影响。
