An Approach towards Defense of DDOS Attacks in Cloud Computing using Confidence based Filtering and Hop Count Filtering Techniques

摘要

Cloud computing is a way of abstracting and outsourcing hardware or software resources over the Internet, often to a third party on a pay-as-you-go basis. As the technology grows, so as the threats and recent Distributed Denial of Service (DDoS) attacks on clouds has become one of the serious threats to this buzzing technology. In this paper, we study the DDoS attack in cloud computing environment and briefly survey different existing techniques for their mitigation. Also, we examine the parameters to resolve the limitations of existing techniques to combat DDoS attacks. In doing so, we propose an algorithm to better combat DDoS attacks using existing methodologies.
