Abstract

Due to the complexity of managing and monitoring large-scale traditional Networks. Software-Defined network (SDN) is the recent network paradigm that has come up to overcome the drawbacks of the traditional network. SDN decouples network control plane from data plane enabling network centralization control and network programmability. Thus simplifying network scalability. However, the vigor of SDN caused of several security challenges and issues associated with various attacks. The current paper aims at introducing a descriptive review of OpenFlow controller-based SDN and the recent existing countermeasures. Moreover, various methods of protecting the controller from such attacks have been discussed which deemed as the valuable contribution in the research field of SDN security

Highlights

As the digital society is growing and everything is almost connected to each other and accessible from everywhere
The protection of controller, switch, and the channel is the main assets in the security of OpenFlow based Software-Defined Network (SDN) as they considered the main threatened objects need to be protected from several attacks like denial of service (DoS), spoofing, hijacking, Man in the middle and so on
SECURITY ISSUES FOR OPENFLOW CONTROLLER BASED SDN: Security issues in OpenFlow controller-based SDN mostly refer to the vulnerabilities at the control plane in which attacker can compromise SDN

Summary

INTRODUCTION

As the digital society is growing and everything is almost connected to each other and accessible from everywhere. Software-defined network is archetypically built up from a huge number of network devices like router, switch and various types of middleboxes like a firewall operated under centralized controller with a lot of complex protocols used to implement them [1]. The protection of controller, switch, and the channel is the main assets in the security of OpenFlow based SDN as they considered the main threatened objects need to be protected from several attacks like DoS, spoofing, hijacking, Man in the middle and so on.

SECURITY ISSUES FOR OPENFLOW CONTROLLER BASED SDN:

Host Hijacking Attack

Spoofing attack
