The command defends DOD information systems, supports military commanders with cyberspace operations, and defends the United States from cyberattacks. In addition to defending against increasing adversarial attempts to compromise military, intelligence, and defense industrial base networks and critical infrastructure, CYBERCOM is focused on countering a wide array of malicious cyberspace activities. Background The origins of CYBERCOM can be traced to the late 1990s, when DOD efforts focused on network centric warfare and strengthening U.S. computer network operations-the precursor to cyberspace operations- through various task forces. The department later established a Joint Task Force for Global Network Operations (JTF-GNO) for defensive cyberspace operations and a Joint Force Component Command for Network Warfare (JFCC-NW) for offensive operations. Both task forces operated under U.S. Strategic Command (STRATCOM). Air Force officials also recognized the importance of cyberspace operations, declaring cyberspace an official Air Force domain in 2005 and initiating work to develop a new cyber command. In 2009, the Air Force established Air Forces Cyber and 16th Air Force as cyber- focused organizations. On June 23, 2009, Robert Gates, then-Secretary of Defense (SECDEF), directed the creation of CYBERCOM, establishing the organization as a subordinate (or sub-) unified command under STRATCOM. Both the JTF-GNO and JFCC-NW were absorbed into the new command, with their missions moving from CNO to cyberspace operations. Initially, CYBERCOM received assistance from the National Security Agency (NSA), including personnel, equipment, and resources to perform its mission. The command reached full operational capability in 2010. In 2016, under Section 923 of the National Defense Authorization Act for Fiscal Year 2017 (NDAA; P.L. 114- 328), Congress authorized establishing CYBERCOM as a unified CCMD. In 2017, the first Trump Administration directed that CYBERCOM be elevated to the status of a Unified Combatant Command. Led by a four-star general or admiral, CYBERCOM is headquartered at Fort George G. Meade in Maryland. The commander is dual-hatted (i.e., simultaneously oversees two distinct organizations) and also serves as the Director of the National Security Agency (DIRNSA). Mission and Organization According to CYBERCOM, its mission is to direct, synchronize, and coordinate cyberspace planning and operations-to defend and advance national interests-in collaboration with domestic and international partners. The command performs four assigned missions: * Defend U.S. critical infrastructure and democratic processes from malicious cyberspace actors; * Defend DOD Information Networks (DODIN); * Integrate options and capabilities in CCMD campaigns and plans; and * Increase DOD cyber effectiveness through collaboration with allies and partners. Components. CYBERCOM is organized into four service components that provide forces to the command: Army Cyber Command, the Navy's U.S. Fleet Cyber Command, Marine Forces Cyberspace Command, and Air Forces Cyber/16th Air Force. The commanders of these service components are dual-hatted as Joint Force Headquarters Cyber (JFHQ- C) commanders. CYBERCOM also has two subordinate unified commands that conduct operations on a continuing basis for the command: the Cyber National Mission Forces (CNMF) and DOD Cyber Defense Command (formerly JFHQ-DODIN). The Cyber Mission Force (CMF), CYBERCOM's operational arm, comprises several cyber mission forces: The CMF consists of the Cyber National Mission Force, the Cyber Protection Force, and the Cyber Combat Mission Force, each with their own associated mission teams. These teams are controlled through the four subordinate service JFHQs and the two subordinate unified commands. Coast Guard Cyber Command, part of the Department of Homeland Security, has a direct support relationship to CYBERCOM. Congress has been exploring the idea of creating a separate cyber military service under CYBERCOM through the Cyberspace Solarium Commission (CSC), created by Congress in the National Defense Authorization Act for Fiscal Year 2019 (NDAA; P.L. 115-232). Fxpanded Xuthorities In view of CYBERCOM's specialized missions that require uniquely trained personnel and equipment, Congress has in 10 U.S.C. §167b provided the command with expanded authorities related to budget, acquisitions, and personnel management processes-authorities that are, in general, broader than those provided to certain other CCMDs and similar to those of the military departments. In 2018, the Trump administration delegated additional authorities to the SECDEF for certain military cyberspace operations, according to DOD. Budget DOD requests funding for CYBERCOM in budget justification documents associated with multiple Defense- Wide accounts: Operations and Maintenance (O&M); Procurement; and Research, Development, Test, and
