Scalable Cloud Defenses for Detection, Analysis and Mitigation of DDoS Attacks

Abstract. Distributed denial of service (DDoS) is considered as one of the most serious threats to emerging cloud computing infrastructures. It aims at denying access to the cloud infrastructure by making it un-available to its users. This can cause important economic and organi-zational damage depending on the type of applications running on the cloud that have become unavailable. This paper proposes an extension to a federated cloud architecture to use scalability and migration of vir-tual machines to build scalable cloud defenses against cloud DDoS at-tacks. The architecture is validated by showing how three DDoS attack scenarios are handled by the DDoS countermeasures
