Security Framework Based on SDN
Yang Yu, Yu Nan Wang, Yang Wei · Advanced materials research · 2014
With the growing demand for information, it has a strategic importance for the future of sustainable development how to create a safe and robust network system to ensure the security of important information. Intrusion detection technology can proactively react against intrusion behavior and adjust its strategies in time. So it provides an effective means for network security to minimize or avoid loss when network system is attacked. It is an important part of network security system. This article first explains the current framework and the working principle of SDN. Then it explains the existing security threats of current framework. Next intrusion detection system based on SDN is proposed after the introduction of the intrusion detection system. And we made experiments to verify it. Finally we analyze the lack of the structure and propose some improvements.
