CHAPTER III
AUTHORITIES, ROLES, AND RESPONSIBILITIES
“The US Government has the responsibility to… ensure that the United States and
its citizens, together with the larger community of nations, can realize the full
potential of the Information Technology revolution.”
1. Introduction
President Obama, 29 May 2009
a. Under the authorities of the Secretary of Defense (SecDef), DOD uses cyberspace
capabilities to shape cyberspace and provide integrated offensive and defensive options. As
directed by USSTRATCOM, USCYBERCOM synchronizes and directs transregional
operations and, in coordination with CCMDs, JS, and Office of the Secretary of Defense
(OSD), liaises with other USG departments and agencies, and members of DIB in
conjunction with DHS. Similarly, as directed, DOD will deploy necessary resources to
support efforts of other USG departments and agencies.
b. The National Military Strategy for Cyberspace Operations (NMS-CO) and the
Department of Defense Strategy for Operating in Cyberspace provide requirements for
national defense in cyberspace and DOD’s role in defending US national interests through
CO.
c. DOD’s Roles and Initiatives in Cyberspace. The NMS-CO instructs DOD to be
prepared to support DHS, as the lead USG agency, in the following cyberspace roles:
national incident response and support to USG departments and agencies in CI/KR
protection. To fulfill this mission, DOD conducts military operations to defend cyberspace,
DOD elements of CI/KR, the homeland, or other vital US interests as directed. If defense of
a national interest is required, DOD’s national defense missions, when authorized by
Presidential orders or standing authorities, take primacy over, and may subsume, the
standing missions of other departments or agencies. The Department of Defense Strategy for
Operating in Cyberspace establishes strategic initiatives that offer a roadmap for DOD to
operate effectively in cyberspace, defend national interests, and achieve national security
objectives.
d. National Incident Response. In addition to DOD’s responsibility to defend the
Nation, DOD provides defense support of civil authorities (DSCA), as directed. DOD
coordinates with DHS and other interagency partners, as described in the National Response
Framework.
e. Critical Infrastructure/Key Resources Protection. CI/KR consist of the
infrastructure and assets vital to the nation’s security, governance, public health and safety,
economy, and public confidence. IAW the National Infrastructure Protection Plan, DOD is
designated as the sector-specific agency for the DIB. DOD provides cyberspace analysis and
forensics support via the DIB Cybersecurity and Information Assurance Program and the
DOD Cyber Crime Center. Concurrent with its national defense and incident response
