Securing Future Wireless Networks: Challenges and Strategies in 5g/6g and Sdn/Nfv Ecosystems

Abstract

The evolution of wireless communication has transitioned from traditional 4G networks to 5G and the upcoming 6G networks, offering unprecedented speeds, ultra-low latency, massive connectivity, and intelligent network management. Alongside this evolution, Software-Defined Networking (SDN) and Network Function Virtualization (NFV) have emerged as critical enablers of flexible, programmable, and scalable networks. However, these advancements also introduce complex security challenges due to increased attack surfaces, virtualization vulnerabilities, and dynamic network configurations. This paper examines the security landscape of 5G/6G networks integrated with SDN and NFV, explores associated challenges, and highlights current strategies and future directions for enhancing network security.
