Software-Defined Networking: A New Approach to Fifth Generation Networks – Security Issues and Challenges Ahead

In order to satisfy the demands of 5G mobile networks, Software Defined Networking (SDN) has been developed. Security concerns, including man-in-the-middle (MITM) assaults, denial of service (DoS) assaults, and other cases are made possible by the separation of the data planes and control planes. Security concerns to each SDN layer are examined in this article, including the application layer, southbound/northbound interfaces, controller, and data layers. The SDN platform’s constituents, from a security perspective, possess some few weaknesses that could be exploited by attackers to carry out harmful operations, influencing the network and its operators. In summary, this work identifies architectural flaws and builds attack vectors at each layer, leading to future development in recognizing the repercussions of attacks and suggesting preventive solutions.
