This paper studies the impact of EDoS attacks with proposed detection mechanism of Web Application Firewall (WAF). The HTTP Request Filtering (HRF) technique is proposed as a detection mechanism and implemented using predefined rules and conditions visa-vis using threshold, throughput and inter arrival time of the requests on WAF. Evaluated analytical queuing model for the proposed defense mechanism and also explains the work flow. This analytical queuing model verified through experimental test-bed to study the implemented WAF performance on the EDoS attacks in Cloud Computing (CC) environment. Evaluated performance metrics are response time, utilization, and throughput and these metrics have used for cost analysis. These results are presented in tables as well as graphs and conclusions are drawn from the study.
