Security Challenges and Solutions in 5G Networks

Technologies like 5G, 6G, and beyond are designed to usher in a new era of services, accompanied by fresh demands and complexities, all geared towards providing seamless and higher data rate mobile connectivity on a global scale. These next-generation networks, surpassing the capabilities of 5G, are anticipated to deliver superior quality of service, exceptionally high data speeds, enhanced network security, increased capacity, minimal latency, and cost-effectiveness. While these technologies hold great promise for network advancement, they also introduce various security concerns and challenges, underscoring the critical importance of network security in the future landscape of wireless communication. This paper delves into a thorough exploration of recent security issues related to 5G, each stemming from the aforementioned key-enabling technologies. It scrutinizes methods to fortify the network’s security while simultaneously addressing the demands of emerging services and the requisites of users. In this manuscript, the challenges of modern-era warfare wireless network scenarios are discussed which are susceptible to attacks and threats. The paper discusses various security overlays that shall be added to strengthen the security of military communication. The paper is supported by a simulated DDoS attack on a 5G core network (user plane).
