Which division of the DHS is responsible for securing transportation in collaboration with other agencies?

The Transportation Security Administration (TSA) is specifically tasked with securing the nation's transportation systems, which include aviation, railways, highways, and public transit. Its primary mission is to ensure the safety and security of travelers and cargo, which it achieves through a range of measures such as security screenings, developing and enforcing regulations, and collaborating with local, state, and federal agencies as well as private sector partners.

The TSA operates under the umbrella of the Department of Homeland Security (DHS) and focuses on implementing security measures designed to prevent acts of terrorism and other criminal activities in transportation. This collaboration is essential, as securing transportation sectors often requires a multi-agency approach, including working closely with law enforcement and private transportation entities to enhance overall security.

Other divisions listed do not focus primarily on transportation security. The Federal Emergency Management Agency (FEMA) deals with responding to and managing disasters. The National Transportation Safety Board (NTSB) investigates transportation accidents to improve safety but is not involved in securing transportation. Customs and Border Protection (CBP) focuses on border security and immigration enforcement, which while related, does not directly address the specific mission of transportation security that the TSA fulfills.
