Cloud
computing with its recent development, made it’s accessible by almost everyone.
Millions and millions of people daily store their data in the cloud platform
and utilize for various kind of need.
In this scenario, distributed denial of
service (DDoS) attacks is one of the common issues in the day-to-day usage,
which severally affects the availability of the resources or services. The
challenge is to create a DDoS detection and mitigation system that can protect
against both volumetric and application-specific resource starvation and
exhaustion attacks. In this paper, a new method named MOTAG has been proposed.
This method of moving-target defence to overcome DDoS attacks will repeatedly
shuffle the assignments between client to server in order to identify the
malicious clients first and then to quarantine them.
