Denial-of-Services (DoS) attacks are nowadays one of the main problems for small and large companies as they entail a high recovery cost in relation to the frequency that they are suffered. Depending on the intensity of the attack launched, these can be defined as high-rate attacks, which seek for a huge shipment of packets in a short space of time, and low-rate attacks, which seek for a continuous delivery of lower proportion of packets for longer time. Being able to detect the latter type is much more complicated due to its similarity with legitimate traffic and, therefore, easily avoids state-of-the-art detection and mitigation measures. The real-time detection of these attacks is certainly a challenge for computer security. This work focuses on presenting some existing detection methods for DoS low-rate attacks as well as analyzing their effectiveness in a simulated traffic environment.
