Cyber-crime is a growing threat that affects everyone, including the maritime industry. There are several things to consider to mitigate your risk. First, install a system that blocks attacks both internally, through plugged-in USB devices, and externally, from data that is delivered from an external source to your yacht. Make sure you update your ECDIS’s operating system. If it is out of date and no longer getting security patches, it’s time to upgrade. Use cyber-secured USB ports that encrypt the data and have built-in virus protection. There are market-available military grade encryptions, ensuring a secure data exchange on the bridge. Also, secure your passwords. Don’t give a hacker admin privileges across your entire on-board network. Finally, it is good practice to download encrypted chart updates onto a USB drive, check it on a remote PC for malware and viruses, and then upload the updated charts.
