Port security refers to the measures and protocols implemented to protect ports and their surrounding areas from threats such as terrorism, smuggling, and piracy. This includes physical security measures like fencing, surveillance cameras, and access control, as well as cybersecurity measures to protect information systems. Additionally, port security involves collaboration among various agencies, including the Coast Guard, Customs and Border Protection, and local law enforcement. These organizations work together to ensure the safety of cargo, vessels, and personnel, while also facilitating the efficient movement of goods through the port.
