SEDoS-7: A proactive mitigation approach against EDoS attacks in cloud computing

Flexible and dynamic services on Cloud Computing (CC) are attracting all types of organizations either big or small, which endow with immense potential to be a game-changer in business optimization and growth. The infrastructure can be fully or partially outsourced and eliminates the need for managing and maintaining expensive internal IT infrastructure which is one noteworthy capital savings for the companies. CC and Software Defined Networking (SDN) are two promising technologies with diverse features and has the potential to dynamically adopt changes without disrupting the web services which was earlier a barrier for On-Premise (On-Prem) and Hosted Solutions. Moreover, dynamic nature of CC and SDN has features to overcome the shortfall compared to the traditional services. A conventional Distributed Denial of Service (DDoS) attack on the server and network resources but In a cloud environment the DDoS attack target the service provider's economic resources which transformed into a new subclass, namely Economic Denial of Sustainability attack (EDoS). In this paper, we put forward an elucidation, namely Software Defined EDoS mitigation at application layer 7 of OSI model (SEDoS-7) with a primary focus on EDOS mitigation.
