Abstract

5G constitutes the next revolution in mobile communications. It is expected to deliver ultra-fast, ultra-reliable network access supporting a massive increase of data traffic and connected nodes. Different technologies are emerging to address the requirements of future mobile networks, such as Software Defined Networking (SDN), Network Function Virtualization (NFV) and cloud computing concepts. In this paper, we introduce the security challenges these new technologies are facing, inherent to the new telecommunication paradigm. We also present a multitier approach to secure Software Defined Mobile Network (SDMN) by tackling security at different levels to protect the network itself and its users. First, we secure the communication channels between network elements by leveraging Host Identity Protocol (HIP) and IPSec tunnelling. Then, we restrict the unwanted access to the mobile backhaul network with policy based communications. It also protects the backhaul devices from source address spoofing and Denial of Service (DoS) attacks. Finally, we leverage Software Defined Monitoring (SDM) and data collection to detect, prevent and react to security threats.
