Slovák, Michal ; Setinský, Jiří (referee) ; Hranický, Radek (advisor)
This thesis deals with the development of a classifier for detecting unwanted requests to a web server using machine learning methods. This approach requires the creation of an annotated dataset and the analysis of common features and characteristics of illegitimate requests that can be used to categorize them. Furthermore, the paper deals with the selection of an appropriate classification algorithm. The resulting model achieves a weighted F1 score of 99.95 %, is reliable and fast, making it suitable for practical deployment.
