Securing Private LTE and 5G Deployments in Hybrid Cloud: A Practical Framework

Combining the benefits of the hybrid cloud infrastructures and the private LTE and 5G networks is a significant step ahead in business network operations, as it increases flexibility, performance, and control.Nonetheless, the convergence also creates a broader area of attack and even security challenges that the traditional models can poorly cover.This review introduces a multi-layered and practical network context on how to offer LTE and 5G-based private networks in hybrid cloud settings based on contemporary cloud-first concepts and telecom-grade security demands.The article addresses such critical elements of this framework as identity and access management, zero trust architecture, secure network segmentation, end-to-end encryption, container and supply chain security, and full observability.This paper proposes a practical framework, synthesizing industrial best practices and peer-reviewed insights, to secure private LTE/5G deployments in hybrid cloud environments.This survey shows the need to harmonize paradigms of telecom and IT security to come up with a unified and future-proofed defense paradigm that would sustain the operation of missioncritical services in distributed cloud-edge platforms.
