Digital Twins for Industrial Control Systems Security

The emergence of Digital Twins in Industrial Control Systems has enabled advances in the test and evaluation of those systems in a low-cost and non-disruptive manner. The authors propose leveraging these benefits even farther, using the conformance of the digital twin to its physical counterpart to enable security testing of Industrial Control Systems for vulnerability assessment and penetration testing. A proof-of-concept system involving a bottle-filling system controlled by a Programmable Logic Controller (PLC) is presented.
