Transportation Systems Sector-Specific Plan: An Annex to the National Infrastructure Protection Plan  [open pdf - 7MB]
"The Transportation Systems Sector-Specific Plan (SSP) is the strategic plan for the sector fulfilling the requirements of Homeland Security Presidential Directive 7 (HSPD-7): Critical Infrastructure Identification, Prioritization, and Protection; and the requirements of the Intelligence Reform and Terrorism Prevention Act of 2004 (as amended by the 9/11 Commission Act)1 for the National Strategy for Transportation Security (NSTS). The SSP consists of a base plan and six modal annexes. The modal annexes for mass transit, maritime, and railroads (including freight and passenger rail) also consolidate strategic planning and infrastructure protection requirements. The Transportation Systems SSP describes collaboratively developed strategies to reduce risks to critical transportation infra¬structure from the broad range of known and unknown terrorism threats. These threats span a multitude of scenarios from lone actors with explosives devices to complex and coordinated assaults such as the 9/11 attack or, potentially, attacks involving weapons of mass destruction. The SSP establishes the strategic goals and objectives to be implemented in order to achieve a shared vision of a safe and secure national transportation system and it explains processes and mechanisms to manage sector risks. The 2010 SSP revises the Systems-Based Risk Management process described in the 2007 version of the SSP, and adopts and amplifies the National Infrastructure Protection Plan (NIPP) framework by describing a process intended to encourage wider participation in risk reduction decisionmaking activities. The main objective of the process is to build a set of programs and initiatives that reduce the sector's most significant risks in an efficient, practical, and cost-effective manner."
