Real time detection and response of distributed denial of service attacks for web services

Abstract

DDoS attacks is a major threat that targets companies and organizations on a daily basis, as reported in the 2012 Information Security Breaches Survey, with the most common target being Web Services. Additionally, the raise of the activism group “Anonymous” and the availability and easiness of DDoS tools in the Internet made this dangerous attacks very popular and reachable for the masses. According to Arbor Networks a DDoS attack can last anywhere between 2 and 6 hours. From the companies prospective, the downtime of their web services, as a result of such an attack, lead companies into loosing valuable profit and customers. In this dissertation a method for DDoS detection by constructing a fuzzy estimator on the mean packet inter arrival times is proposed. The problem is divided into two challenges, the first being the actual detection of the DDoS event taking place and the second being the identification of the offending IP addresses. Strict real time constraints were imposed for th ...
