Cloud Computing is at the forefront of Information Technology and has revolutionized computing in many ways. As numerous enterprises move into the cloud, the chances of being targeted by attacks especially Application Layer Distributed Denial of Service (DDoS) attacks will increase dramatically. Such attacks are capable of exhausting a victim's resources (such as servers, network, storage and applications), denying access and overloading with bogus requests, resulting in significant economic loss. Unlike the traditional DDoS attacks which occur at the network layer, these attacks occur at the application layer where the detection is comparatively difficult, since the attacker already has a valid connection to the victim server. Fuzzy logic is a precise algorithm for imprecise system that plays an important role in decision making process of the incoming HTTP requests to decide whether the request is malicious or genuine. Hence, a Fuzzy Logic based Application Layer Mitigation is necessary to handle such threats for maintaining cloud based services and ensuring availability of enterprise systems. Hence, this thesis is focused on combining evidences of the existing architectures (used for protecting and tracing DDoS attacks) as well as filtering malicious requests using DDoS mitigation systems and Fuzzy Logic.
