Security Issues in Software-Defined Networks Article Swipe
Software-Defined Networking (SDN) is dynamic in nature for future intelligent networks and function applications with reduced operating cost through simplified software, hardware and management. The SDN challenges are performance, security, scalability and interoperability combined with the proposal in potential solutions direction. The Distributed- Denial of Service (DDoS) attack rate is growing year by year. In 2016, the largest attack rate was 800 Gbps. There exists a contradictory relationship between SDN and DDoS attacks. On the one hand, it is easy to detect DDoS attacks in SDN, but on the other hand, SDN itself becomes, a victim of DDoS attacks and potential DDoS vulnerabilities. The good thing with SDN is, it is a good tool to defeat and react against DDoS attack. An SDN survey says it provides a big research opportunity for security and can greatly impact networks security research in different ways. The paper shows some security challenges, with the various threats possible at different parts of SDN. It also, shows DDoS attacks on different SDN layers and its available security solutions, and discusses some directions for detection and mitigation mechanism of DDoS attack in SDN. In future, security policies will be built over the controller to make a tolerant system for DDoS attacks.
