We develop a new security firewall application that can be deployed in Software-Define Network (SDN). Our proposed application was designed based on layer-based security filtering techniques to monitor the attackers that strengthen the network-wide security in SDN. In previous research, we succeed the monitoring on single controller. But, to manage the flow more specifically, the firewall application with having more mature features to control the flow of packets is needed. To overcome this issue, we discuss implementing the multi-controller concept with high performance computing resources.
