Analysis of Slow Read DoS attack

The idea and techniques of DoS(Denial of Service) / DDoS(Distributed DoS) attack strategy become more effective and more complex. In our research, we focus on a Slow Read DoS attack which is one of sophisticated DoS techniques. This technique prolongs time to read the response from theWeb server, although an attacker sends a legitimate HTTP request. When an attacker sends many legitimate requests, he can keep many open connections to Web server and eventually cause DoS situation. In this paper, we analyze the effectiveness of Slow Read DoS attack using the virtual environment. Furthermore, we propose the Slow Read DDoS attack based on collusion technique and discuss the countermeasure scheme.
