A Reactive Defense Mechanism based on an Analytical Approach to Mitigate DDoS Attacks and Improve Network Performance
Palvinder Singh Mann, Dinesh Kumar · International Journal of Computer Applications · 2011
The Distributed denial of service attacks (DDoS) have become more and more frequent and caused some fatal problems in the recent time.Internet users experience denialof-service (DoS) attacks every day.Our inboxes are swamped with spam containing subject lines that sometimes fool us; our search-engine queries return many irrelevant results; and online auctions are plagued by corrupt database records filled with intentionally misleading keywords and many more .Intense research have been done to detect and defend such attacks, however, many solutions are still in the phase of theoretical studies.Some of them may have certain practical value, but they have to reconstruct the existing network and the routing instruments with great cost.In this paper we are going to present an Analytical approach which will employ Reactive Defense Mechanism to mitigate the DDoS attack and further improve network performance in terms of less computation time.Further the simulation result proves it to be a better result oriented approach.
