Overview of Security of Virtual Mobile Networks
This work tackles security issues for mobile network operators and users in emerging 5G-based shared infrastructures, but it is incremental as it offers a review rather than new methods or data.
The article addresses the security challenges in Virtual Mobile Networks (VMNs) enabled by 5G technologies like virtualization and cloud computing, providing an overview of potential solutions to manage complex security requirements in this integrated environment.
5G is enabling different services over the same physical infrastructure through the concepts and technologies of virtualization, softwarization, slicing and cloud computing. Virtual Mobile Networks (VMNs), using these concepts, provide an opportunity to share the same physical infrastructure among multiple operators. Each VMN Operator (VMNO) can have own distinct operating and support systems. However, the technologies used to enable VMNs have their own explicit security challenges and solutions. The integrated environment built upon virtualization, softwarization, and cloudification, thus, will have complex security requirements and implications. In this vain, this article provides an overview of the security challenges and potential solutions for VMNs.
