What GAO Found
According to data provided by Department of Defense (DOD) components, DOD has established almost 440 organizations that contain about 61,000 military and civilian personnel (and over 9,500 contractors), to conduct cyberspace operations. These organizations are most often aligned with U.S. Cyber Command (CYBERCOM) or retained by the military services and conduct a mixture of offensive, defensive, and DOD Information Network operations (see figure). CYBERCOM-aligned organizations include organizations such as Navy cyber strike activities and Army cyber protection battalions that oversee tactical Cyber Mission Force teams. Military service organizations include units such as Air Force communications squadrons and Marine Corps radio battalions. Other organizations include cybersecurity service providers that provide network protection services to non-service components, such as the Defense Threat Reduction Agency and the Defense Advanced Research Projects Agency.
Department of Defense Organizations Conducting Cyberspace Operations
To enable organizations conducting cyberspace operations, each unit is supported by organizations providing budgetary, personnel, policy, and training support. GAO identified 70 organizations and about 3,400 personnel that provide support to cyberspace operations. These include the Office of the Secretary of Defense, military department, and service headquarters, and other organizations.
GAO found that some of the functions of these organizations may overlap. These include training courses the military services provide to organizations conducting cyberspace operations and the administration of DOD's 23 cybersecurity service providers that conduct cybersecurity for DOD organizations. Although some overlap can be intentional and appropriate, unnecessary overlap can lead to organizations paying for the same service or product twice or more. As DOD considers the future organization and composition of its cyberspace operations forces, it will be important to take steps to reduce cost and inefficiencies while maintaining mission effectiveness.
Why GAO Did This Study
The U.S. and its allies face sophisticated cyber threats from both state and nonstate actors. To counter these threats, DOD conducts cyberspace operations to defend the nation, support allies and partners, and protect its DOD Information Network.
Conference Report 118-301 includes a provision for GAO to review DOD's management of cyberspace operations. GAO (1) identified the type and number of organizations and personnel that conduct cyberspace operations and (2) evaluated the extent to which there is overlap between organizations that provide budgetary, personnel, policy, or training support for cyberspace operations.
GAO reviewed relevant documents, including DOD guidance, Secretary of Defense memorandums, and organizational command briefs. GAO collected and analyzed data from 434 organizations conducting and 70 organizations supporting cyberspace operations that were identified with DOD. GAO also interviewed relevant officials, such as those from the offices of the DOD and the military services' principal cyber advisors.
