Assessment and Experience Using Open-Source NPP Environments for Cyber-Security Training

Hahn, Andrew S.; Rowland, Michael T.; Laros, James H.; Lamb, Christopher L.; Valme, Romuald V.

The use of high-fidelity, real-time physics engines of nuclear power plants in a cyber security training platform is feasible but requires additional research and development. This paper discusses recent developments for cybersecurity training leveraging open-source NPP simulators and network emulation tools. The paper will detail key elements of currently available environments for cybersecurity training. Key elements assessed for each environment are: (i) Management and student user interfaces, (ii) pre-developed baseline and cyber-attack effects, and (iii) capturing student results and performance. Representative and dynamic environments require integration of physics model, network emulation, commercial of the shelf hardware, and technologies that connect these together. Further, orchestration tools for management of the holistic set of models and technologies decrease time in setup and maintenance allow for click to deploy capability. The paper will describe and discuss the Sandia developed environment and open-source tools that incorporates these technologies with click-to-deploy capability. This environment was deployed for delivery of an undergraduate/graduate course with the University of Sao Paulo, Brazil in July 2022 and has been used to investigate new concepts involving Cyber-STPA analysis. This paper captures the identified future improvements, development activities, and lessons learned from the course.
