Maritime OT under pressure: why ship-to-shore data paths need hardware-enforced direction
maritime data diode security: practical guidance for secure one-way data flow architectures.
Summary: Modern vessels are floating data centres—navigation, engine management, emissions reporting, and fleet optimisation all generate rich telemetry. That connectivity collides with a harsh threat landscape and tightening regulatory expectations.
Unique maritime constraints
Satellite links, mixed vendor maintenance models, and crew-operated systems create a wide attack surface. Yet operators still need timely shore-side analytics for maintenance, compliance, and fuel efficiency. The tension is obvious: export visibility without handing attackers a path back into machinery spaces.
Regulatory tailwinds
Expectations from bodies such as IMO and instruments like the EU NIS2 directive push owners toward demonstrable cyber risk management. Directional publishing architectures play well in board-level conversations about “how we prove segregation.”
