The maritime sector has become more connected than ever before. There is an ongoing race to connect, digitalise and deliver smarter vessel systems that enable more remote access and support. However, this increased connectivity has also made vessels and their crews vulnerable.
It is becoming increasingly evident that human factors play a major role in managing the cyber risks of onboard systems. The majority of cybersecurity incidents can be traced back to human error intentionally or unintentionally creating cyber vulnerabilities. We encourage ship owners and operators to raise awareness of cyber risks with both the crew and shore-based teams. Better awareness significantly changes the cyber risk profile of fleet operations.
CyberOwl, a DNV company, provides cybersecurity protection, monitoring and 24/7 incident response support for maritime and offshore assets.

Risk Focus: Vessel Cyber Security - Guidance for Crew
In collaboration with CyberOwl, we have released a new edition of Risk Focus: Vessel Cyber Security, designed specifically as Guidance for Crew. This edition provides easy-to-understand and easy-to-follow guidance for crew on how to prevent and minimise cyber risks to onboard systems. It also briefly looks at how cyberattacks have grown over the years, the key risks the industry is facing and how industry standards are helping to deal with these risks.
"“7 deadly sins” of cyber insecure behaviour" posters and stickers
Ensuring that basic cyber hygiene is maintained can go a long way towards keeping shipboard systems cyber safe. The crew have an important role to play in this. In order to ensure good hygiene, there are rules for each of the “7 deadly sins” of cyber insecure behaviour that crew can follow to significantly reduce cyber risk to shipboard systems. Each deadly sin is represented by a “cyber monster” that serves as a scary reminder.
