Enhanced EDoS-Shield for Mitigating EDoS Attacks Originating from Spoofed IP Addresses

Cloud computing has become one of the fastest growing segments in IT industry. A cloud introduces resource-rich computing platforms, where adopters are charged based on the usage of the cloud's resources, known as "pay-as-you-use" or utility computing. With this model, a conventional DDoS attack targeting servers and network resources is transformed in a cloud environment to a new attack that targets the cloud adopter's economic resource, namely Economic Denial of Sustainability (EDoS) attack. In this paper, we advocate a novel solution as an enhancement to prior work, namely EDoS-Shield, to mitigate the EDoS attacks originating from spoofed IP addresses. We design a discrete event simulation experiment to evaluate its performance and the results show that it is a promising solution to mitigate the EDoS attacks originating from spoofed IP addresses. The enhanced EDoS-Shield technique also outperforms the original EDoS-Shield in terms of performance and cost metrics.
