missions, DOD will also support DHS and other USG departments and agencies to ensure all
sectors of cyberspace CI/KR are available to support national objectives. CI/KR protection
relies on analysis, warning, information sharing, vulnerability identification and reduction,
mitigation, and aiding of national recovery efforts. Defense critical infrastructure (DCI)
refers to DOD and non-DOD assets essential to project, support, and sustain military forces
and operations worldwide that are a subset of CI&KR. GCCs have the responsibility to
prevent the loss or degradation of the DCI within their AORs and must coordinate with the
DOD asset owner, heads of DOD components, and defense infrastructure sector lead agents
to fulfill this responsibility. CCDRs may act to prevent or mitigate the loss or degradation of
non-DOD-owned DCI only at the direction of SecDef IAW Department of Defense Directive
(DODD) 3020.40, DOD Policy and Responsibilities for Critical Infrastructure. This action
must be coordinated with the Chairman of the Joint Chiefs of Staff (CJCS) and the Under
Secretary of Defense for Policy (USD[P]). The Director of DISA is responsible for matters
pertaining to the identification, prioritization, and remediation of critical DODIN
infrastructure issues, as the lead agent for the DODIN sector of the DCI. Likewise, DOD is
responsible to support the DHS coordination of efforts to protect the DIB and the DODIN
portion of the DIB.
