A Systematic Literature Review: Security Vulnerabilities in Private 5G Networks: Challenges and Mitigation Strategies

As industries demand ultra-dependable, low-latency connectivity, private fifth generation (5G) networks have emerged as a critical solution. Unlike conventional technologies such as 4G or Wi-Fi, private 5G networks offer tailored advantages, including guaranteed service continuity, enhanced reliability, and customizable security features. These networks are particularly valuable in sectors such as industrial automation, healthcare, and smart cities, where stringent security, privacy, and performance requirements are paramount. Despite their advantages, private 5G networks introduce significant security challenges, particularly concerning the confidentiality, integrity, and availability of data and services. This thesis investigates security vulnerabilities in private 5G networks through a systematic literature review (SLR). It identifies the key challenges associated with deploying and managing private 5G networks, analysing the risks they introduce. Additionally, the study examines existing strategies and mitigation approaches discussed in the literature. Furthermore, it highlights research gaps and suggests potential directions for future studies to enhance the security of private 5G networks.
