Hull & Firewall: Cybersecurity for Superyachts

Field notes

The page organizes the vessel as a shared attack surface spanning bridge and navigation equipment, satcom and VSAT, propulsion and automation, guest systems, and crew access. Its proposed controls include separate VLANs, vessel-specific firewall rules, MFA, endpoint detection, encrypted offline backups, and logged privileged access. The engagement is presented as four stages followed by optional ongoing monitoring, with a displayed 24/7 incident line for vessels operating away from local IT support.
