This bill aims to bolster the security of United States ports against potential threats posed by foreign cranes, particularly those from "covered foreign countries." It mandates the Secretary of Homeland Security, through the Cybersecurity and Infrastructure Agency (CISA), to inspect newly constructed foreign cranes that connect to the internet for potential security risks before they are placed into service at U.S. ports. Within 180 days of enactment, the Secretary must also assess the security risks of all existing and newly constructed foreign cranes at U.S. ports and take any high-risk cranes offline until they are certified safe. The legislation introduces significant prohibitions to mitigate long-term risks, forbidding the operation of any new foreign crane at a U.S. port if the contract for its procurement was entered into on or after the bill's enactment date. Furthermore, existing foreign cranes operating at U.S. ports will be prohibited from using foreign software five years after the bill becomes law. A "foreign crane" is defined as one with information technology or operational technology components, or software, manufactured by an entity under the ownership, control, or influence of a "covered foreign country," which includes nations identified as foreign adversaries.
