Cyberattack Generator
Gregr, Filip ; Smékal, David (referee) ; Hajný, Jan (advisor)
This thesis is focused on developing a tool that is capable of generating cyber attacks. In the opening there are introduced some attacks using the ISO/OSI application layer protocols. Specifically, these are attacks known as Slowloris, RUDY, Slow Read, HTTP flood, and dictionary attack on the SSH. These attacks are implemented into an existing DoSgen Linux tool that already contains several famous network attacks. The main part of the thesis is devoted to the description of the tool and to the implementation of its own extension. The created tool is practically tested in an experimental enviroment against the Apache web server. Part of the thesis is the documentation for the improved DoSgen tool.

Apache module for the DoS attack mitigation
Ruman, Róbert ; Sikora, Marek (referee) ; Jurek, Michael (advisor)
Táto práca sa venuje mitigácii viacerých typov útokov DoS. Naším cieľom bolo vytvoriť vlastný modul apache, ktorý dokáže zmierniť útoky typu flood, ako aj logické útoky. Modul bol vytvorený v jazyku C pomocou programu VS Code. Po vytvorení modulu sme vykonali viacero testov na získanie údajov, aby sme mohli náš modul porovnať s už existujúcimi modulmi apache. Porovnaním výsledkov testov sme dospeli k záveru, že náš modul dokáže zmierniť oba typy útokov. Výsledky testov sú vizualizované pomocou grafov v prílohe.
