SDN is changing the networks around the world by changing the traditional way of control plane and data plane working. All the network with SDN is controlled using SDN controller and due to its centralized management, it brings large number of benefits to network industry. There are some limitations also which are under review in this paper like Security of the SDN controller. As centralization of the network means that it can be controlled from a single device and all the control plane is implemented using the single controller and its security is vital in the SDN. DDOS attacks can create a lot of issues in the network and can disrupt the whole data center network services integrated with the controller. This paper explains the DDOS attacks and how they can be implemented using hping tool in Kali Linux to disrupt the services of the controller and how it can be prevented by using the inbuilt Linux Firewall.
