In announcing his proposal for the Department of Homeland Security (DHS), the President stated that the Federal government's first priority was the protection and defense of the American people. Achieving true homeland security requires technology that guarantees real-time information sharing and improves decision-making. For example, a border patrol agent in Tijuana must be able to communicate with the Customs station in the port of New York and the Coast Guard base in Miami on a real-time basis. A world-class, unified IT infrastructure linking component agencies to the new Department is essential to accomplish these goals. In view of these security challenges, the purpose of this memorandum is to advise selected heads of DHS component agencies that redundant homeland security IT infrastructure systems will be considered for consolidation or integration. Spending by DHS component agencies' on IT infrastructure will total at least $360M in FY02 and is projected to grow to at least $780M in FY03. Consolidating and integrating infrastructure presents significant opportunities for savings while providing the best investments for our homeland security mission. Therefore, agencies affected by the proposed DHS must: Cease temporarily all IT infrastructure system development and planned modernization efforts above $500,000 pending an expedited review of all DHS component agencies' investments, Identify any current or planned spending on IT infrastructure not included in Attachment A to the memo, Participate in the Homeland Security IT Investment Review Group led by the Office of Homeland Security (OHS) and OMB.
