Storms and navigation errors used to be the top threats at sea. Today, it's also the USB drive on the bridge or an open Wi-Fi network in port. Cyber risks on board are more real than ever.

Here’s what every crew member should understand:

🔹 1. A ship is an IT system
Modern vessels rely on ECDIS, engine automation, ballast control, satellite comms, and even crew personal devices. All of it is connected — and all of it can be compromised.

🔹 2. The weakest link is usually human
Phishing emails, plugging in infected USBs, sharing passwords — most attacks happen not because of hackers, but because of simple mistakes.

🔹 3. Basic rules matter
– Never connect personal devices to the ship’s network
– Don’t open attachments from unknown emails
– Don’t install software without approval
– Change passwords regularly
– Report unusual system behavior (like ECDIS glitches or time/date errors)

🔹 4. It's not just IT’s responsibility
Cybersecurity is now part of overall ship safety — alongside physical security and fire safety. Ignoring it can lead to disciplinary action or a lost job opportunity.

📌 Many shipping companies already include cybersecurity in pre-boarding briefings.
Some even ask officers about it during interviews.

If you want to stay ahead, learn the basics — and show you’re thinking beyond your watch duties.
