Abstract: The increasing incidence of distributed denial-of-service (DDoS) attacks has made softwaredefined
networking (SDN) more vulnerable to the depletion of controller resources. DDoS attacks
prevent the SDN controller from processing all incoming data efficiently, potentially disrupting a
network or denying legitimate users access to network services. Thus, the protection of the SDN
controller is crucial, especially from the ones that exploit the SDN characteristics. In this paper,
the authors propose an efficient detection approach for low- and high-rate DDoS attacks on the
controller with a high detection rate and a low false positive rate by adapting a dynamic threshold
algorithm rather than a static one and proposing a new rule-based detection mechanism. In addition,
the proposed approach was evaluated using eight simulation scenarios representing all potential
attacks against the SDN controller in terms of attack traffic rates (low or high), sources (either single
or multiple hosts), and targets (single or multiple victims). The experiment results show that the
proposed approach is more effective than the existing approaches based on attack detection and false
positive rates.
