The invention of 5G has significantly transformed the healthcare sector by enabling real-time data transmission, remote surgeries, AI-driven diagnostics, connected ambulances, and continuous patient monitoring. However, the integration of 5G into the healthcare system introduces complex functionalities and challenges relevant to security and privacy, ranging from network vulnerabilities to data breaches. This chapter explores the existing and emerging security frameworks designed to safeguard 5G-enabled healthcare ecosystems. We provide a detailed analysis of potential threats, evaluate existing cybersecurity solutions, and propose a comprehensive security architecture tailored for 5G healthcare environments. This chapter also discusses regulatory, ethical, and technical dimensions, emphasizing the importance of a holistic approach to secure digital health infrastructures.
