%0Computer Program %TARCADE (Advanced Reactor Cyber Analysis and Development Environment) %XSAND2025-11780O ARCADE (Advanced Reactor Cyber Analysis and Development Environment) software performs cybersecurity experiments on Defensive Cyber Security Architectures (DCSA) for Distributed Control Systems (DCSs). The application is integrated into a cohesive environment that performs cyber risk analyses and reduces costs. ARCADE can investigate the entire cyber-attack surface of a DCS from the physics of control, down to the firmware of individual components with automated efficiency. ARCADE has five major functional components: the Data Broker system, the virtualization environment, the cyber-attack simulator, the cyber-physical analysis system, and the physics simulator. Sandia National Laboratories is a multimission laboratory managed and operated by National Technology & Engineering Solutions of Sandia, LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525. %AValme, Romuald %AHahn, Andrew %ABeauchaine, Adam %AGray, Titus %Rhttps://doi.org/10.11578/dc.20251016.9 %Uhttps://www.osti.gov/doecode/biblio/167158 %CUnited States %D2024 %GEnglish %2USDOE %1NA0003525 2024-09-10
