Port authorities and terminal operators manage the intersection of maritime OT — crane control systems, vessel traffic services, and berth management — with commercial IT systems for cargo tracking, customs interfaces, and logistics coordination, creating a converged attack surface where a cyberattack can halt global supply chains, as the NotPetya attack demonstrated when it disrupted Maersk's operations at 17 ports worldwide. The US Coast Guard's Maritime Cyber Risk Management strategy and IMO Maritime Cyber Risk Management Resolution MSC-FAL.1/Circ.3 are driving port operators toward Zero Trust controls for both OT and IT systems.
