Attack Scenario-based Validation of the Idaho CPS Smart Grid Cybersecurity Testbed (ISAAC)

The use of smart and distributed devices is increasing in Cyber Physical Systems (CPS). The smart and distributed devices are capable of extensive inter- and intra- networking. Consequently, cyber attack attempts against CPS have been increasing in recent years. The potential for widespread loss of resources for utilities is high if a cyber-attack is executed successfully on a CPS. Realistic and comprehensive cyber-physical testbeds are becoming increasingly necessary to analyze and secure CPS organizations. One such comprehensive and realistic testbed, ISAAC - the Idaho CPS Smart Grid Cybersecurity Testbed, was previously presented. Validating testbeds with realistic experiments is of paramount importance in increasing the usability of a testbed. We present a mapping of ISAAC to the Purdue reference model. We also validate ISAAC by performing a realistic attack-scenario on the testbed. Our results indicate that ISAAC can simulate realistic scenarios.
