Transportation Security: Background and Issues for the 117th Congress

The nation’s air, land, and marine transportation systems are designed for accessibility and efficiency, two characteristics that make them vulnerable to terrorist attack. While hardening the transportation sector is difficult, measures can be taken to deter terrorists. The enduring challenge facing Congress is how best to implement and finance a system of deterrence, protection, and response that effectively reduces the possibility and consequences of terrorist attacks without unduly interfering with travel, commerce, and civil liberties. This report examines issues in aviation security, transit and passenger rail security, port and maritime security, and security at land border ports of entry.
