Executive Summary

Known for a long time, Distributed Denial-of-Service (DDoS) attacks are still prevalent today and cause harm on the Internet on a daily basis. The main mechanism behind this kind of attacks is the use of so called botnets, i.e., networks of compromised machines under the control of an attacker.
