Homeland Security Presidential Directive 11 (HSPD-11): Comprehensive Terrorist-related Screening Procedures (Aug. 27, 2004) (full-text).
To build upon and provide additional guidance related to Homeland Security Presidential Directive 6, in August 2004, the President signed HSPD-11. Among other things, this directive required the Secretary of Homeland Security — in coordination with the heads of appropriate federal departments and agencies — to submit two reports to the President (through the Assistant to the President for Homeland Security) related to the government’s approach to terrorist-related screening.
The first report was to outline a strategy to enhance the effectiveness of terrorist-related screening activities by developing comprehensive and coordinated procedures and capabilities. The second report was to provide a prioritized investment and implementation plan for detecting and interdicting suspected terrorists and terrorist activities. Specifically, the plan was to describe the "scope, governance, principles, outcomes, milestones, training objectives, metrics, costs, and schedule of activities" to implement the U.S. government’s terrorism-related screening policies.
