Maritime cyber security


In many fields of life, we rely on computers to aid us and the maritime industry is no exception. Cyber-attacks are one of the greatest threats in the 21st century. In the past, most vessels relied on the ‘air gap’ to defend against cyber-attacks. Nowadays vessels are connected: ranging from internet for crew welfare and administration to connected devices brought onboard by passengers or crew.

Cyber-attacks on ships can render the ship inoperable, cause accidents or even disrupt vital services. RH Marine provides tailored cyber security solutions to mitigate risks and sustain continued operation.

Certified experts


RH Marine has certified Cyber Security Experts to advise you on cyber security and help you to manage operational security risks. As system integrator for specialized maritime industries we understand the importance of combining operational knowledge with advanced cyber security solutions in order to have a safe, reliable and efficient operation.

RH Marine is a trusted partner of 15+ top-class navies worldwide.

Basic Protection


Protection starts with the basics: By implementing the basics, most risks are mitigated. Some low-end actions that will reduce the risk of a cyber-incident are:

  • Provide USB power plugs at workstations to prevent crew to use the USB ports on operational computers
  • Apply security patches for computers and network devices regularly
  • Change the default user credentials of computers, network devices and webcams
  • Have service laptops onboard for maintenance purposes; Don’t allow (third party) service engineers to use their service laptops

High-end protection


For vessels, companies and navies where the impact would be higher, more advanced measures should be taken. The defence-in-depth strategy provides multiple layers of measures. If one measure fails other measures can still prevent a potential cyber-security incident. These measures are a combination of information, application and network security.

The defence-in-breath strategy aims at securing the supply chain from developer to end-user both on a software and hardware level. At any stage of the supply chain, malware can be introduced. Select suppliers and sub-suppliers carefully during the build and maintenance of the vessel. Both strategies should be taken into account to mitigate risks as much as possible.

Cyber threats


The cyber threats are real for all vessels, but the risks may differ. For navies, a denial of service attack can severely reduce the operational capabilities in times of need. For offshore vessels, a ransomware attack may cause serious financial or environmental damages. Onboard yachts, data leaks can significantly impact the privacy onboard.

The 'air gap' alone is no longer a valid mean of cyber security and while with most newbuild vessels cyber security is taken into account, measures should be taken for currently operating vessels as well.
