The digitalisation of maritime operations and the reliance on technology and network connectivity for daily onboard and on shore operations means that shipping is vulnerable to the threat of cyber incidents.
To help crew prepare, both on the bridge and in the engine room, the new “Cyber Security Workbook for On Board Ship Use” includes several checklists of how to protect, detect, respond and recover from a cyber incident, and thereby offers a practical and easy to use guide for the master and the officers.
