Industrial control systems are complex systems that employ a wide range of hardware, software, and network protocols to control physical processes critical to the smooth functioning of society. It is important for control system operators to receive quality training to respond to various cyber events such as operator actions and cyber attacks. Hands-on training exercises with real-world control systems allow operators to learn various defensive techniques and see the real-world impact of

In addition, cyber events can have unforeseen effects that potentially cause physical harm to the system. The potential damage to exercise equipment threatens to make high-fidelity training exercises prohibitively expensive. This thesis presents a method for accelerating training exercises. Specifically, the method entails simulating and predicting the effects of a cyber event on a partiallysimulated control system that has the ability to speed up the simulated industrial process while allowing the control hardware to continue operating as intended. A hardware-in-the-loop system comprised of a software-modeled water tank controlled by a commercially-available programmable logic controller is used to demonstrate the feasibility of this method. In order to verify the accuracy and consistency of the proposed method, experimentation includes validation testing with an actual water tank controlled by the same model programmable logic controller used in the simulated system. Together, the water tank and programmable logic controller represent a partial, real-world control system. The experiment requires the simulated system to replicate a cyber event iv I had to opportunity to work together and learn so much. Luke M. Bradford, 2d Lt, USAF viii
