The United States has made significant progress in securing the nation from terrorism since the September 11, 2001 attacks. As a result of this attack, certain recommendations where made from the 9/11 commission report. One of which is Developing and Implementing risk-based Transportation Security Strategies.
DHS has made significant advances in risk-based security since 9/11, focusing on intelligence- driven, layered security across all transportation modes. This approach emphasizes pre-screening for passengers and cargo, while focusing resources on those who pose the greatest threat to the nation‘s transportation networks. Some these advances include:
Conducting baseline security assessments across aviation, maritime, surface transportation sectors;
Forging international consensus on historic new global aviation standards; Strengthening the security of the global supply chain;
Collecting and analyzing advanced passenger and cargo information; and Supporting risk-based state and local prevention efforts (U.S. Department of Homeland Security, 2011, p.4).
