Analysis of Automated Model against DDoS Attacks

Today Distributed Denial of Service (DDoS) attacks are causing major threat to perform online business over the Internet. Recently several schemes have been proposed on how to prevent some of these attacks, but they suffer from a range of problems, some of them being impractical and others not being effective against these attacks. Our previous work proposed an automated model that deals with the overall DDoS problem. With a new packet marking technique and agent design, our approach has many advanced features to minimize the DDoS attacks within a single ISP domain. In this paper we discuss different types of attacks that are possible on our model and propose techniques to counteract the identified attacks. We will also discuss security protocols for communication between different entities in our model.
