In today’s era, the Software-Defined Networking (SDN) framework streamlines network administrators’ job by isolating the information plane from the control plane. As a result, network setup is made possible through the use of a programmable interface for software development in areas including security management and the centralized logical controller. These areas have complete network visibility and provides greater control over the entire network. These SDN benefits make the network more vulnerable to attacks, and the impact of attacks is far more severe than in conventional networks, where network components are protected against attacks and the frequency of attacks is restricted. Safety concerns are divided into manipulated and record planes by SDN, and this architectural recomposition opens up new opportunities and presents new difficulties. According to the consensus, SDN capabilities will eventually lead to better protection. However, in its current state, SDN has the potential to make networks more vulnerable to attacks and more difficult to maintain. With a focus on the control plane, one of the least studied but most crucial aspects of safeguarding this technology, we provide a thorough analysis of the SDN safety domain in this chapter. We review the most recent SDN developments and pinpoint the most important SDN flaws. The chapter also examines the numerous security services built on top of this technology to address key issues in defending the SDN control plane.
