Early Detection of Distributed Denial of Service Attack in Era of Software-Defined Network
Bineet Kumar Joshi, Nitin Joshi, Mahesh C. Joshi · 2018
A Distributed Denial of Service (DDoS) attack try to make services or resources unavailable to legitimate customers of that service or resource. These attacks are relatively easy to perform and extremely hard to detect in early stages. Different types of detection techniques were proposed by researcher to detect DDoS in its early stages but due to closed nature of networking devices, no promising results were produced. However, with the advents of Software-Defined Network (SDN), situation has changed. SDN is a cutting edge technology, which separates control plane from data plane. Its features, like programmability and centralized view of network, can be used to overcome the difficulties faced by researches. In this paper, we discussed different detection techniques of DDoS and how these techniques can be made more effective by leveraging the unique features of SDN.
