IEEE TRANSACTIONS ON RELIABILITY 1 A Survey of Securing Networks using Software Defined Networking

Abstract—Software Defined Networking (SDN) is rapidly emerging as a new paradigm for managing and controlling the operation of networks ranging from the data center to core, enterprise and home. The logical centralization of network intel-ligence presents exciting challenges and opportunities to enhance security in such networks, including new ways to prevent, detect and react to threats, as well as innovative security services and applications that are built upon SDN capabilities. In this paper we undertake a comprehensive survey of recent works that apply SDN to security, and identify promising future directions that can be addressed by such research. Index Terms—software defined networking, OpenFlow, net-work security, threat detection, threat remediation, network verification, anonymization, data offloading, network functions virtualization. I
