An Efficient Methods to Prevent Denial of Service Attack
S. Brintha Rajakumari · 2014
The recent increase of their power and their use by organized criminal organizations make necessary to consider them as one of the major issues IT infrastructures will have to face in the next few years. Trying to defeat those attacks without understanding their technical aspects is illusory. In this paper, we propose to use this web site graph structure to mitigate flooding attacks on a website, using new web referral architecture for privileged service (WRAPS). WRAPS allows a legitimate client to obtain a privilege URL through a simple click on a referral hyperlink, from a website trusted by the target website. Using that URL, the client can get privileged access to the target website in a manner that is far less vulnerable to a distributed denial-of-service (DDoS) flooding attack than normal access would be. Our empirical study demonstrates that WRAPS enables legitimate clients to connect to a website smoothly in spite of a very intensive flooding attack, at the cost of small overheads on the website's ISP's edge routers. We discuss the security properties of WRAPS and a simple approach to encourage many small websites to help protect an important site during DoS attacks.
