The Current Trends of DDoS Detection in SDN Environment

Distributed Denial of Service (DDoS) attacks are one of the dangerous threats to networks, as they are easily operated and difficult to detect, so they frequently occur, and this field of research is fertile to find efficient ways to detect and deal with this type of attacks. Software Defined Networking (SDN) which represents one of the most elegant technologies to make network management and configuration easy by increasing network programmability. SDN is characterized by their centralized management and control, so it becomes more attractive to DDoS attacks to affect the whole network. This research presents a survey on security trends on SDN environment and investigate the most known methods for detecting a DDoS attack from different sources and analyze them to highlight the way to the interested researchers in the field.
