Abstract
The landscape of cyber and other threats to Cyber Physical Systems (CPS), such as the Power Grid, is growing rapidly. Smart and distributed devices capable of extensive inter- and intra- networking are playing a more significant role in CPS thereby increasing the risks associated with such systems. Realistic and reconfigurable testbeds with correctly implemented security policies capable of mitigating threats are needed to develop, test, improve, and deploy practical cybersecurity solutions for CPS. This thesis primarily discusses the design and implementation of ISAAC, the Idaho CPS Smart Grid Cybersecurity Testbed, a cross-domain, distributed, and reconfigurable testbed, which emulates a realistic power utility and provides researchers with the tools needed to develop and test integrated cybersecurity solutions. Furthermore, the thesis showcases the post-implementation capabilities of the testbed through a two-pronged validation: i) mapping with an ICS reference architecture model; and ii) an emulated cyber-attack experimental scenario.
