PSC cyber requirements, ready before the inspection.

Port State Control inspections increasingly include a cybersecurity component, aligned with IACS UR E26/E27 and the IMO's MSC.428(98) guidance. The direction is clear: regulators want to see that cyber risk management is a documented, working process on the vessel, not a binder on a shelf.

The practical consequence for fleet managers: inspection now asks for evidence of cyber controls, incident readiness, and continuous monitoring.

1. A documented cyber risk assessment. Current, vessel-specific, and signed off.

2. Access control evidence. Who can reach bridge systems, and how that is enforced.

3. Monitoring records. Logs showing the vessel is watched, anomalies are detected, and responses are documented.

4. Incident response readiness. A plan, and crew who can demonstrate they know it.

Most fleets fail the evidence test, not the policy test. They have procedures on paper but no data trail proving the procedures run. An inspector cannot verify a monitoring process from a PDF.

The fix is telemetry: continuous logs from the vessel's own network, structured so an export answers the inspector's questions in minutes. This is exactly the gap M-SOC and the Haris edge node are built to close.

1. Baseline now. Run a passive exposure scan so you know your current state.

2. Instrument the fleet. Collect and store monitoring logs continuously, retrofits are cheaper than you expect.

3. Document the loop. Assessment, controls, monitoring, review, with timestamps.

4. Rehearse once. A single drill that produces the evidence an inspector would request.
