Software-defined mobile network (SDMN) architecture integrates software-defined networks, network functions virtualization, and cloud computing principles in mobile networking environments to transform rigid and disparate legacy mobile networks into scalable and dynamic ecosystems. However, because SDMN architecture separates the control and data planes, it will significantly change the way security is managed and applied for mobile networks. In this article, the authors discuss the security challenges, vulnerabilities, and opportunities that need to be investigated and addressed for future SDMNs. It also highlights how common security threats in IP networks such as the Internet are now applicable in new open and IP-based SDMNs.
