at the Department of Homeland Security. Department of Defense and CIP The U.S. Department of Defense is responsible for protecting its portion of the government's critical infrastructure. But as part of the CIP program, DoD has responsibilities that traverse both the national and department-wide critical infrastructure. PDD-63 identified the responsibilities DoD had for critical infrastructure protection. First, DoD had to identify its own critical assets and infrastructures and provide assurance through analysis, assessment, and remediation. DoD was also responsible for identifying and monitoring the national and international infrastructure requirements of industry and other government agencies, all of which needed to be included in the protection planning. DoD also addressed the assurance and protection of commercial assets and infrastructure services in DoD acquisitions. Other DoD responsibilities for CIP included assessing the potential impact on military operations that would result from the loss or compromise of infrastructure service. There were also requirements for monitoring DoD operations, detecting and responding to infrastructure incidents, and providing department indications and warnings as part of the national process. Ultimately, DoD was responsible for supporting national critical infrastructure protection. In response to the requirements identified in PDD-63, DoD categorized its own critical assets by sector, in a manner similar to the national CIP organization. The DoD identified a slightly different list of infrastructure sectors for those areas that specifically required protection by DoD. DoD's organizational structure for critical infrastructure protection reflects, complements, and effectively interacts with the national structure for CIP. DoD sectors There are ten defense critical infrastructure sectors that are protected by the DoD. These include: Financial Services - Defense financial services support activities related to officially appropriated funds. These activities include the disbursement of cash, receipt of funds, and acceptance of deposits for credit to officially designated Treasury general accounts. This sector also provides financial services to individuals and on-base organizations, including deposits, account maintenance, and safekeeping. The Defense Finance and Accounting Service is the lead component for the Financial Services sector. Transportation - The Defense Transportation System, or DTS, includes resources that support global DoD transportation needs. These include surface, sea, and lift assets; supporting infrastructure; personnel; and related systems. Transportation Command, or USTRANSCOM, is the single manager for DoD transportation. Public Works - Public works includes four distinct physical infrastructure sectors: electric power, oil, and natural gas, water and sewer; and emergency services, such as fire, medical, and hazardous material handling.
