Definition & Explanation

Port security encompasses the measures taken to protect harbour facilities, vessels, personnel, and cargo against unauthorised access, sabotage, smuggling, and terrorist threats. Controls begin at the gate – vehicle checks, identity verification, access barriers, and CCTV surveillance form the first layer of defence. The binding international framework is provided by the IMO's ISPS Code, which requires port facilities to maintain approved security plans and appoint a Port Facility Security Officer (PFSO). Effective port security also demands continuous coordination among terminal operators, customs authorities, border agencies, and national security services; a single gap in that network can jeopardise the entire port's operation. Many states layer additional national regulations on top of the international baseline.
