OpenFlowSIA: An optimized protection scheme for software-defined networks from flooding attacks

In this paper, we propose an optimized protection mechanism (OpenFlowSIA) for Software-Defined Networks from flooding attacks (Distributed Denial-of-Service) based on Support Vector Machine and our proposed algorithm called the Idle-timeout Adjustment (IA). Our methodology not only utilizes SVM advantages in classification such as high accuracy and little processing time, but also applies effectively the IA algorithm and coherent policies to protect network from resource exhaustion caused by flooding attacks, particularly for the SDN controller and OpenFlow switches. Through comprehensive experiments, the OpenFlowSIA scheme illustrates that it can be an innovative solution to secure and save the network resources under flooding attacks in the Software-Defined Networks.
