Abstract

IaaS, PaaS, and SaaS models collectively form the Cloud Computing Infrastructure. The complexity of interrelationship of service models is very high and so security issue becomes essentials and must be developed with utmost care. Distributed DOS attacks are a major concern for different organization engaged in using cloud based services. The denial of service attack and distributed denial of service attacks in particular in cloud paradigms are big threat on a cloud network or platform. These attacks operate by rendering the server and network useless by sending unnecessary service and resource requests. The victims host or network isn't aware of such attacks and keeps providing recourses until they get exhausted. Due to resource exhaustions, the resources requests of genuine users doesn't get fulfilled. Severity of these attacks can lead to huge financial losses if, they are able to bring down servers executing financial services. This chapter presents DOS threats and methods to mitigate them in varied dimensions.
