Muhammad Aamir, Muhammad Shoaib Arif · International Journal of Information Technology and Computer Science · 2013
Different types and techniques of DDoS attacks & defense are studied in this paper with some recent informat ion on attacks dominated in year 2012 (1st Quarter).We further provide simu lation based analysis of an FTP server"s performance in a typical enterprise network under distributed denial of service attack.Simulat ions in OPNET show noticeable variations in connection capacity, task processing and delay parameters of the attacked server as compared to the performance without attack.DDoS detection and mit igation mechanisms discuss ed in this paper main ly focus on some recently investigated techniques.Finally, conclusions are drawn on the basis of survey based study as well as simulation results.
