Cloud-based DDoS attack detection and defence system using statistical approach

In the recent era, business and IT domain rely on the cloud as it has evolved as the potential service model and lots of people jumped on the bandwagon to seek profit out of the cloud computing environment. The cloud is highly vulnerable and its risk associated with unpatched machines is exposed to distributed denial of service (DDoS) attacks. According to cloud security alliance group DDoS is the major security attack in the cloud and the impact and effects on virtual machines is much unexplored. Despite numerous DDoS solutions, there is a need for a dish fit for gods' in cloud. Hence, the proposed system defends the DDoS attacks in cloud by monitoring the performance distortion, detecting multilayer attacks using statistical method. Based on the attack variances with normal using chi-square statistics, DDoS attack sources are enlisted and communicated to the defence system to filter attack traffic and protect the cloud. © 2019 Inderscience Enterprises Ltd.
