By way of a quick follow-up to last Friday’s DAU LOG Blog post “Life Cycle Logistics Workforce Cybersecurity Competencies”, wanted to let the community know that the Department has also issued a new unclassified DoD Cybersecurity Reference Architecture Version 5.0.

According to this new document, which is dated January 30, 2023, “…in 2020, the DoD Chief Information Officer (CIO) subsumed the Joint Information Environment (JIE) into the broader DoD Digital Modernization Strategy (DMS). The DoD CIO approved the Digital Modernization Infrastructure (DMI) Executive Committee (EXCOM) Charter that formalized governance, roles, and responsibilities for implementing select strategy elements of the DMS. JIE architectures aligned to the DoD Information Enterprise Architecture, however; the transition to the DMS also subsumed this historical trend. In 2021, E.O. 14028 directed the Federal Government to "make bold changes and significant investments" and use zero trust (ZT) to modernize cybersecurity. The Cybersecurity Reference Architecture (CSRA) version 5 will deliver on this imperative for the DoD by aligning to the DMS and integrating ZT principles to define data protection for cloud, traditional, and hybrid information systems. Version 5 of the CSRA advances DoD’s defense business systems, national security systems, and critical infrastructure / key resources through an evolution to integrate ZT principles. This evolution is the DoD approach to meet the intent described in Section 3 of E.O. 14028, Improving the Nation’s Cybersecurity and Section 1 of National Security Memorandum 8, Improving the Cybersecurity of National Security, Department of Defense, and Intelligence Community Systems to modernize cybersecurity through adoption of ZT architecture (ZTA).”
