5G is expected to lead to a hyper-connected society with the promise of applications of high social and economic value. It should not only solve the common problems of today’s networks, but also provide a large capacity. 5G networks require a flexible infrastructure that is resilient to overloading and secure to known cyber-attacks to meet the desired expectations. Software Defined Networking (SDN) can be considered as one of the building blocks of 5G networks. We will firstly present the limitations of today’s networks in this chapter. Then we will present solutions to secure the networks by using software-defined networking components. This concept is referred to as the “SDN for Security” While SDN facilitates securing networks in general, it introduces additional challenges; mainly, the vulnerabilities of the SDN components such as the controller have to be addressed. The concept that we refer to as the “Security for SDN” aims at securing SDN assets and is discussed in the sequel. After reading this chapter, readers will obtain a comprehensive overview of the limitations of traditional networks, how SDN overcomes those limitations and the security issues thereof.
