Transport security refers to the measures and protocols implemented to protect the safety and integrity of transportation systems. This includes safeguarding passengers, cargo, and infrastructure from threats such as terrorism, theft, and vandalism. Various agencies, including the Transportation Security Administration (TSA) in the United States, work to ensure that transportation methods like air travel, railways, and shipping are secure. Effective transport security involves a combination of technology, personnel training, and regulatory compliance. Screening processes, surveillance systems, and emergency response plans are essential components. By addressing potential vulnerabilities, transport security aims to maintain public confidence and ensure the smooth operation of transportation networks.
