A Software Defined Network (SDN) is an architecture used to form agile and flexible networks. SDN's goal is to improve network control, allowing service providers to respond rapidly to changing requirements. In a SDN, an administrator or a network engineer can configure the traffic from a centralized control console without having to touch individual network switches. Due to the fact that the control plan is entered by SDN as a network manager, a Single of Failure Point (SPoF) is also introduced. If SDN can not be reached by network devices, the network will crash. Distributed Denial of service (DDoS) attack is a way to make SDN Controller inaccessible. In this paper are presented the potential vulnerabilities of SDN Controller that can be exploited for DDoS attack as well as the presence of methods of detection and attenuation of these attacks.
