The evolution of communications networks into the cyber warfighting domain presents challenges across the doctrine, organization, training, materiel, personnel and facilities (DOTMLPF) spectrum. The Department of Defense (DOD) created new joint and service headquarters to address these challenges and to address the cyberspace risks to national security. While these headquarters have been able to make some progress in addressing cyber challenges, the current DOD approach to cyber depends on antiquated doctrinal concepts, mission command constructs, and indefensible network architectures.No single organization in the DOD has the responsibility to build, operate and defend cyber networks. The lack of a clear cyber chain of command greatly hinders cyberspace operations. Also, the current DOD network architecture is so complex that military cyberspace is indefensible. Compounding these problems, the current service-centric cyber approach is extremely inefficient. Can a DOD enterprise approach to cyberspace correct these deficiencies, effectively support the GCCs and enable USCYBERCOM to accomplish its mission?
