A SOFTWARE DEFINED SECURITY ARCHITECTURE FOR SDN-BASED 5G NETWORK

Software Defined Networking (SDN) is considered to meet the future needs of the 5G mobile networks. However, there have been only a few works so far that address the security issues in SDMN (Software Defined Mobile Networks), and all the proposed approaches have their drawbacks. So, in this context, a new security paradigm based on SDN introduces many opportunities and provides the potential to solve the security problem in the mobile core network. In this paper, we present the SDS-SC, a software defined security architecture for SDN based 5G network. With centralized security controller that communicates with SDN network controller, flexible and network-aware security services could be provided for mobile users on-demand. We also highlight how security applications could be developed easily in our architecture through application interface on top of the security controller.
