Abstract : With the increase in digitization, cyber attacks have been on the rise. In this paper, we discuss the adverse effects a DOS attack has on an SDN architecture. Due to this centralized architecture, the control logic may be prone to a variety of security threats, vulnerabilities and other attacks. With the help of a hashing mechanism that is triggered on the basis of threshold values, we diagnose and prevent a DOS attack from disrupting the entire network. This paper illustrates efficient and cost effective algorithms that can be implemented in an SDN network to safeguard it from the ruinous effects of a DOS attack.
