DATCONS: Protecting Web-Based QoS from DDoS Attacks

Distributed denial-of-service (DDoS) attacks pose a great danger to the Internet. In this paper, DDoS attack tolerance using cooperative network structure (DATCONS) is proposed, which uses suitable and flexible models at different network locations, gathers information from different layers, propagates the information, provides differentiation of the services and ensures the level of the Web QoS based on the idea of distributed attack detection and protection. DATCONS aims to filter out DDoS attacks as close to the source as possible. The framework and network environment were prototyped to show the effectiveness of DATCONS in different attack scenarios
