Mitigation of DDoS attacks in cloud computing
Preeti Daffu, Amanpreet Kaur · 2016
Cloud computing provided its users with the more convenient way to use the resources and with a model where the users are charged as per the usage of their resources. The model is known as “pay-as-per-usage”. Users can access the cloud services from anywhere at any time. They only need a working internet connection. Despite of all these benefits, cloud comes with some drawbacks also. The issue related to security of cloud is a biggest concern today. The attackers and hackers flood the network with attack packets and these are hard to identify as everything present on cloud is in virtual form. DDoS (Distributed Denial of Service) is a cloud-specific attack in which attack source is always more than one; multiple machines attacks on a user by sending packets with large data overhead. Such attacks make the resources unavailable to the user by overwhelming the network with unwanted traffic. In this research paper the main aim is to filter out the data packets with large data overhead to avoid DDoS attack and the Mean Time to Security Failure (MTSF) will be calculated so that an alternative dynamic plan can be adopted.
