Plugging a USB drive into a ship or yacht computer always seems harmless.
Until that innocent little stick turns out to be carrying malware and suddenly your chart system, bridge workstation, or engine control computer is having a very bad day.
USB devices used for updates, maintenance, or quick file transfers are still one of the easiest ways to introduce cyber trouble onboard. Commercial fleet or private yacht, the risk does not care how polished the teak looks.
A basic USB control policy is not overkill. It is common sense.
Use approved devices only.
Scan removable media before use.
Restrict USB access on critical systems.
Train crew not to treat personal devices like trusted equipment.
Because sometimes operational disruption does not start with a hacker in a dark room. It starts with someone saying, "Just plug this in for a second."
Constellation Cyber Consultancy helps fleets and yacht operators build practical cyber controls that actually work onboard.
