Cyber Training Architecture, Enabling Digital Twin Environments
In 2019, The U.S. Army Program Executive Officer for Simulation, Training and Instrumentation (PEO STRI) released an initial cyberspace operations training platform prototype called the Persistent Cyber Training Environment (PCTE). The PCTE platform includes tools to rapidly create ‘Digital Twins’ that replicate cyberspace operational environments in a virtualized platform for the Cyber Mission Force (CMF) to execute realistic training and mission rehearsals. PCTE is laying the groundwork for these virtualized assets to connect to real world physical security assets such as industrial controls systems (ICS) that are otherwise not practical to emulate. To address this challenge, PEO STRI and the larger DoD cyber training community are utilizing an evolutionary architecture to rapidly integrate PCTE with real world physical security assets. This paper introduces evolutionary architecture and discusses the cyber training community’s approach for evolving a cyber training architecture over time while simultaneously delivering capability to the CMF.
