Siddhant- A Journal of Decision Making

The cloud computing scenario runs on the notion that delivered resources should be allocated and de-allocated on demand, at the same time as providing reasonable performance. These services can vary from dynamically virtual machines to flexible hosted software services. The symptoms of a DoS attack include unusually slow network performance (opening files or accessing web sites), unavailability of a particular web site, inability to access any web site or any other such unexpected behavior that points towards a congested network. It has covered a potential attack called Xml-Based Denial of Service (X-DoS), which is a lethal attack aimed at the services that cloud computers provide. The proposed solution to defend against such attacks is the SOTA model and implementing it on a cloud system, which is called a Cloud TraceBack (CTB). CTB demonstrated that it can be used in an actual X-DoS attack so the cloud victim could trace the attack back to the source.
