Specifically, ships are currently operating using VSAT support and Inmarsat voice and data communication.

As 5G satellites gradually take their place in the maritime sector, they will improve high-quality voice and data communications and cybersecurity will be available at a lower price point.

Thus, 5G will also strengthen connectivity and cybe security, for shipping companies and vessels as well.

In the meantime, the European Space Agency is developing a 5G satellite implementation, whose trials are expected to be completed by 2020. Therefore, shipping companies have to begin preparations for the development of new digital services from the 5G satellite once they are available.

In light of the 5G network, the Korean Register will introduce it as a reference model to address cyber threats in ships and companies.

Shipping companies are primarily focused on the security isolation of IT and OT systems; To assist companies, 5G applied the following model:

KR reports that security isolation issues can be dealt with in two ways, depending on the threat model.

As shown in the image above, the technical mechanism addresses the need for security isolation. The design subcategories considered are enforcement location and isolation granularity; another method is to apply policy design. Cybersecurity is an important factor to be considered in the ship design stage.

 Cybersecurity threat can be reduced by policy design, without affecting the system by installing of a heavy cybersecurity solution in the OT system

... Korean Registry concludes.
