A Survey on Methods to Defend against DDoS Attack in Cloud Computing

摘要

Cloud computing is a revolution in IT technology by providing a shared pool of virtualizes resources for its users to pay as they use. This technology is based on two crucial concepts as virtualization and abstraction, which increased the ability of on demand access through the available resources in the cloud without any investment in new infrastructure. Security is one of the most challenges for both cloud provider and cloud consumer. In recent years DDoS attack is one of the most serious threats against cloud computing. Since cloud built on the fundamental of distributed environment, it is easier for an intruder to launch a DDoS attack against available resources and services of a cloud computing environment. This paper introduces cloud computing, Virtualization and DDoS attack. A review and comparison of the existing methods against DDoS attack on cloud computing is presented as well.
