۵G Core Network Security: Architecture, Challenges, and Defenses

The ۵G Core (۵GC) network introduces a paradigm shift in mobile communications, leveraging software-defined networks (SDN), network function virtualization (NFV), service-based architectures, and network slicing. While these bring flexibility, performance, and scalability, they also open new attack surfaces and security challenges. This article presents a holistic view of ۵G Core network security: the architecture and key principles, threat vectors at different layers (control plane, data plane, interfaces, virtualization), privacy and identity issues, mitigation techniques, open research problems, and emerging trends such as zero trust, AI-based defense, and post-quantum transition.
