摘要: Software Defined Networking (SDN) has the potential to enable novel security applications that support flexible, on-demand deployment of system elements. It can offer targeted forensic evidence collection and investigation computer network attacks. Such unique capabilities are instrumental intrusion detection is challenged by large volumes data complex topologies. This paper presents an innovative approach coordinates distributed traffic Monitors attack Correlators supported Open Virtual Switches (OVS). The conduct anomaly perform deep packet inspection for signature recognition. These elements take advantage complementary views information availability on both control planes. Moreover, they collaboratively look flooding constituents possess different characteristics in level abstraction. Therefore, this able not only quickly raise alert against threats, but also follow it up with careful verification reduce false alarms. We experiment SDN-supported collaborative detect TCP SYN flood attacks Global Environment Network Innovations (GENI), a realistic virtual testbed. response times accuracy, context small medium corporate network, have demonstrated its effectiveness scalability.
