A Security Proposal Based on a Real Time Agent to Protect Web Services Against DoS Attack

Abstract

This paper describes a novel proposal based on a real time agent to detect and block denial of service attacks within web services environments. The real time agent incorporates a classification mechanism based on a Case-Base Reasoning (CBR) model, where the different CBR phases are time bounded. In addition, the reuse phase of the CBR cycle incorporates a mixture of experts to choose a specific technique of classification depending on the feature of the attack and the available time to solve the classification.
