Detection of slow-rate DDoS attacks
Sikora, Marek ; Frolka, Jakub (referee) ; Blažek, Petr (advisor)
This diploma thesis is focused on the detection and protection against Slow DoS and DDoS attacks using computer network traffic analysis. The reader is introduced to the basic issues of this specific category of sophisticated attacks, and the characteristics of several specific attacks are clarified. There is also a set of methods for detecting and protecting against these attacks. The proposed methods are used to implement custom intrusion prevention system that is deployed on the border filtering server of computer network in order to protect Web servers against attacks from the Internet. Then created system is tested in the laboratory network. Presented results of the testing show that the system is able to detect attacks Slow GET, Slow POST, Slow Read and Apache Range Header and then protect Web servers from affecting provided services.

Slow Dos Attacks Detection And Mitigation
Sikora, Marek
This article investigates the detection and mitigation methods against Slow DoS (Demand of Service) attacks. This research is focused on Slowloris, Slow POST, Slow Read, and Apache Range Header attacks. Detection methods are based on network traffic analysis and anomalous traffic monitoring. When the attack is detected, the attacker is blocked and web server resources are released. Methods are implemented as an intrusion prevention system software.
