From traffic operations centers and Advanced Traffic Management Systems (ATMS) to field signal cabinets and traffic control devices, transportation systems use digital and automated components to manage physical processes—the flow and control of traffic, vehicles, and pedestrians. These components present numerous attack vectors for cyber attack, against both the signaling systems and the networks and control systems that manage them. Developments such as intelligent transportation systems and autonomous vehicles exponentially magnify the threat landscape for the controlled, safe, and reliable operation of transportation systems.
