Review of Mitigation Techniques to Overcome Security Attacks on SDN

The current rate of growth of technology requires better and modern networks which the traditional network is not capable of providing, which is due to issues in scaling or manual configuration of physical infrastructure. Further the lack of knowledge and the shortage of skill set or skilled professionals required with technical expertise has been one of the big issues, which is very much concerned for present scenario. This has led to the need of software defined network architecture wherein control and data plane are decoupled which helps in configuring the network for the changing demands. However this also poses some challenges like security. This brings the necessity to identify techniques to mitigate the security attacks on SDN. This research study reviews different mitigation techniques to overcome the security attack on SDN. Additionally, this research work identifies the limitations and future work, which can be done in this direction.
