The fifth generation of mobile technologies (5G) has brought many technological advancements. With significantly faster transmission speeds compared to
the fourth generation (4G), improved reliability, lower latency, and higher density of connected devices, 5G networks have the potential to transform many
industrial sectors. However, with new technological advancements come new security challenges, making cybersecurity in 5G more important than ever before.
Key challenges in 5G include ensuring adequate security measures, the security
of standards, protection of supply chains, and the security of end-user devices.
The thesis initially addresses the key features and technologies of 5G networks,
which introduce new surfaces for cyberattacks. It then presents general types of
cyberattacks and best protection practices, divided into five phases, along with
security mechanisms related to these phases. The concluding section focuses
on standards and recommendations for ensuring security in a 5G environment,
highlighting perspectives from various organizations, such as 3GPP and ENISA.
Finally, the thesis offers security recommendations for enterprises.
