From the introduction: "“Zero Trust is the term for an evolving set of cybersecurity paradigms that move defenses from static, network-based perimeters to focus on users, assets, and resources. Zero Trust assumes there is no implicit trust granted to assets or user accounts based solely on their physical or network location (i.e., local area networks versus the Internet) or based on asset ownership (enterprise or personally owned).”1 Zero Trust (ZT) requires designing a consolidated and more secure architecture without impeding operations or compromising security. The classic perimeter/defense-in-depth cybersecurity strategy repeatedly shows to have limited value against well-resourced adversaries and is an ineffective approach to address insider threats. The DoD Cybersecurity Reference Architecture (CS RA) documents the Department’s approach to cybersecurity and is being updated to become data centric and infuse ZT principles. ZT supports the 2018 DoD Cyber Strategy, the 2019 DoD Digital Modernization Strategy, the 2021 Executive Order on Improving the Nation’s Cybersecurity, and the DoD Chief Information Officer’s (CIO) vision for creating “a more secure, coordinated, seamless, transparent, and costeffective architecture that transforms data into actionable information and ensures dependable mission execution in the face of a persistent cyber threat.” 2 ZT should be used to re-prioritize and integrate existing DoD capabilities and resources, while maintaining availability and minimizing temporal delays in authentication mechanisms, to address the DoD CIO’s vision."
