Software-Defined Networking (SDN) is becoming an increasingly relevant networking approach day by day, due to its myriad benefits over Traditional hardwired-based Networks. Still, SDN Controllers are popular for their weak security mechanism. This paper discusses the vulnerability issues in the security of SDN Controllers. The Control layer is the most vulnerable to network attacks in the three-layered SDN architecture. DDoS attacks on the Control layer can cause a Single Point of Failure for the entire SDN network. OpenDaylight (ODL) and Open Networking Operating System (ONOS) are the top two leading open-source SDN Controllers. We found out that ODL and ONOS Controller fail to provide any protection from DDoS attacks. SDN developers have compromised the security aspects of the Controller to improve its performance. In this research article, an attempt is being made to address such security vulnerabilities of SDN with ODL and ONOS Controllers for DDoS attacks.
