An approach for slow distributed denial of service attack detection and alleviation in software defined networks

Over the last few years, need for programmable networks has captured interest of industrialists and academicians. It led to development a paradigm called software defined network (SDN). separates intelligence into control plane forwarding logic data plane. This architecture gives scope various security issues which denial service (DoS) is most common challenging detect. paper focuses on detection mitigation slow DoS attack Slowloris Apache2 server in SDN based networks. The proposed solution mechanism (SDMM). Mininet, an emulator, SimpleHTTPServer are used simulation same implemented using Zodiac FX OpenFlow switch, Ryu controller server. SDMM algorithm detects mitigates prolonged typical as well with low bandwidth high delay 240-280s accuracy 100% 98% respectively. uses expectation burst size key factor detection.
