5G is an emerging technology that will be used in many areas (not least in transport) and opens new horizons in data sharing, smart grids and Internet of Things. However, the risks associated with its deployment should not be underestimated, especially in terms of cybersecurity.
In the future, 5G suppliers, operators and customers will be forced to invest heavily in network security, staff training and adaptation of architectures and monitoring systems, also because the frequency of updates will be much higher. As is well known, one of the identified vulnerability factors also stems from the link between the technology provider and the government of a third State. This is why diversification of suppliers is encouraged as far as possible.
To cope with these risks, it is necessary not only to diversify but also to invest more in authentication security, operator training, emergency management and disaster recovery planning.
