This paper advocates for increasing the utilization of hybrid modeling and simulation technologies for understanding and developing mitigations for cyber threats upon Industrial Control Systems (ICS). It first outlines the challenges to PCS security that can be addressed using these technologies. The paper then describes Virtual Control System Environments (VCSE) that use this approach and briefly discusses security research that Sandia has performed using VCSEs. It closes with recommendations to the ICS security community for applying this valuable technology.
