Enhancing 5G Infrastructure to Withstand Emerging Digital Threats

The advent and rapid expansion of 5G technology brings substantial advancements in communication capabilities, characterized by ultra-low latency, enhanced bandwidth, and massive device connectivity. However, this technological evolution simultaneously exposes critical infrastructure to a broad spectrum of sophisticated and evolving digital threats. This paper addresses the security challenges inherent to 5G networks and proposes a set of advanced, intelligent solutions tailored to their architectural complexity. The proposed measures include Zero Trust Architecture (ZTA), artificial intelligence-based behavioral analytics, federated learning, blockchain-enabled device authentication, and secure orchestration of network slicing. These methodologies offer a scalable, proactive, and privacy-conscious security framework capable of ensuring operational resilience and data integrity. The objective of this work is to emphasize the necessity of adopting adaptive and future-ready defense mechanisms to safeguard the robustness and reliability of 5G infrastructures against emerging cyber threats.
