Defence for Distributed Denial of Service Attacks in Cloud Computing

Cloud computing offers users high-end and scalable infrastructure at an affordable cost. Virtualisation is the key to unlocking cloud computing. Although virtualisation has great benefits to the users, the complexity in its structure, introduces unseen and forcible threats to the security of the data and to the system infrastructure. This investigates the exploitation of compromised virtual machines to execute large-scale Distributed Denial-of-Service (DDoS) attacks. A critical review of most recent intrusion detection and prevention systems to mitigate potential DDoS attacks is presented.
