Securing the secrets of 5G: Mitigating eavesdropping threats and enhancing network integrity
M Gowtham Krishna Sai · 2025
5G is a fifth-generation network that is intended to be more dependable, faster, and have a lower latency than the past 4G network. It offers a more reliable connection, can connect more devices simultaneously, and operates on a higher-frequency spectrum that can carry enormous amounts of data. Although 5G networks offer numerous benefits, their open network architecture renders them vulnerable to security threats. This study discusses the serious security issues of eavesdropping, a passive attack that can provide unauthorized access to private information, including financial and personal information. The integrity and secrecy of 5G networks are at serious risk because passive eavesdropping is difficult to detect. To solve this problem, we thoroughly review the suggested fixes for guarding against eavesdropping attacks on 5G networks. This review covers handover procedures, pilot signals, device-to-device, communication, user equipment itself, and other attack vectors. The use of strong encryption, the establishment of secure communication protocols, and careful network traffic monitoring to spot any unusual activity are key preventative steps to reduce the danger of eavesdropping. We identified and assessed various eavesdropping solutions in this study, providing a thorough analysis of their effectiveness and implementation.
