5G networks is the future backbone of our increasingly digitised economies and societies. Billions of connected objects and systems are concerned, including in critical sectors such as energy, transport, banking, and health, as well as industrial control systems carrying sensitive information and supporting safety systems. Ensuring the security and resilience of 5G networks is therefore essential.
The report is based on the results of the national cybersecurity risk assessments by all EU Member States. It identifies the main threats and threats actors, the most sensitive assets, the main vulnerabilities (including technical ones and other types of vulnerabilities) and a number of strategic risks.
This assessment provides the basis to identify mitigation measures that can be applied at national and European level.
The report identifies a number of important security challenges, which are likely to appear or become more prominent in 5G networks, compared with the situation in existing networks:
These security challenges are mainly linked to:
- key innovations in the 5G technology (which will also bring a number of specific security improvements), in particular the important part of software and the wide range of services and applications enabled by 5G;
- the role of suppliers in building and operating 5G networks and the degree of dependency on individual suppliers.
