Cloud services are fully managed by service providers and being sold on demand and are dynamically scalable to meet infinite demand cheaply and reliably. The denial-of-service attacks have become more targeted on cloud services. The elastic nature of cloud allows scaling of service beyond the economic means of the purveyor thereby paying huge cloud-based service bills for unwittingly serving large amounts of undesired (illegitimate) traffic. In this book, Mr. M Naresh Kumar presented a detailed Introduction, Literature Survey and a brief comparison of various mitigation techniques with limitations. The author presented a novel architecture(An in-cloud eDDoS mitigation service) along with an algorithm with neat detailed diagrams. This in-cloud eDDoS mitigation service can alleviate Low and High rated DDoS attacks which can be used on-demand and is charged on pay-per use basis by guaranteeing the availability of service.
