<![CDATA[Software Defined Networking is the latest breakthrough in modern network modeling where control plane and data plane have been separated from each other. Where on the SDN control plane is placed on the controller in charge of organizing and providing all the needs that exist in the network. The controller will monitor the state of the network and also perform the repair process in case of damage to the network, one of which can be caused by Denial of Service (DoS) and Distributed - Denial of Service (DDoS) Attacks attacks. With implementing a centralized firewall on the controller, the controller can quickly detect when a network attacks occurs either by hosts hosted on their domains or by hosts in other network domains, so the process of own attack subscribing becomes faster and more effective. That things proved based on the average attack time the required subscription is about 6.042 seconds with average use of cpu resource is 18.4% and bitrate received by host victim 13.582 Kbps after attacking by the controller, indicating that the implementation of centralized firewall in the controller can quickly detect and subscribe to attack that occur, using a resource cpu that is not too large and pressing the number of packets of data sent so as to save on bandwidth usage in the network.]]>
