DDoS Attacks in 5G Networks: Characteristics and Analysis of Defense Strategies

Abstract

5G networks introduce transformative technologies like SDN, NFV, Network Slicing, and MEC that enable ultra-low latency and massive IoT connectivity, but simultaneously create new security vulnerabilities. The software-defined control plane, shared infrastructure, and proliferation of insecure IoT devices make DDoS attacks significantly more sophisticated and damaging than in previous mobile generations. This paper analyzes the evolving DDoS threat landscape in 5G environments and evaluates various defense strategies including SDN-based mitigation, machine learning approaches, network slicing isolation, and Zero Trust Architecture, aiming to assess current protective capabilities and highlight areas for future research.
