Defense Acquisitions: Joint Cyber Warfighting Architecture Would Benefit from Defined Goals and Governance, Report to Congressional Committees [open pdf - 501KB]
From the Highlights: "Cyberspace is a growing, human-made environment that touches many parts of life, including education, economic development, health, and other public services. For DOD, cyberspace is as important as the traditional land, sea, air, and space warfighting domains. To integrate these disparate cyber systems into a more cohesive capability, U.S. Cyber Command introduced an overarching vision for cyber capabilities known as the Joint Cyber Warfighting Architecture. The Senate Armed Services Committee included a provision for GAO [Government Accountability Office] to review the status of the JCWA [Joint Cyber Warfighting Architecture]. This report (1) describes the JCWA concept, systems, and planned capabilities; and (2) assesses the extent to which DOD has defined interoperability goals and a governance structure to guide JCWA cyber system acquisitions."
