Cybersecurity

Executive Summary

Ransomware incidents at Asian port terminals and shipping agencies are accelerating. IMO MSC-FAL.1/Circ.3 requires maritime cyber risk management to be addressed in Safety Management Systems by 2021 — but enforcement and verification quality varies significantly across fleets and terminals in the region. This checklist provides a structured, IMO-aligned framework for executives to assess and close the most critical cyber gaps before an incident forces the issue.

The highest-priority exposures for Asian maritime operators in 2025 are: OT/IT network segmentation failures on vessels and terminals, uncontrolled third-party vendor access to operational systems, absence of tested incident response plans, and GNSS/AIS spoofing vulnerability. Each section of this checklist maps to a specific control domain and references the relevant IMO, BIMCO, or insurance guideline.
