Advanced tool for generating modern Slow DoS attacks
Hrůza, Tomáš ; Člupek, Vlastimil (referee) ; Sikora, Marek (advisor)
In today’s world, cyber threats are becoming increasingly sophisticated. Those threats include SDoS (Slow Denial of Service) and SDDoS (Slow Distributed Denial of Service) attacks, which employ advanced methods to disrupt normal service operations. These attacks are particularly difficult to detect and are effective because they simulate the behavior of legitimate users with slow internet connections. The topic of SDoS attacks is relatively new and not thoroughly documented. To respond to potentially newly devel- oped attacks, it is necessary to understand the principles of currently known attacks and have the practical capability to create them in order to develop effective countermeasures in the future. This thesis focuses on the development of an advanced tool for generating modern SDoS attacks. The main contribution of this work is the enhancement of the generator to create distributed attacks, the creation of an intuitive interface, and more options for monitoring the progress of individual attacks. The theoretical part introduces the topic of internet connection establishment and explains the properties of TCP and IP protocols in detail. It then clarifies the theory of secure communication over the internet using the HTTPS protocol and provides a comparison of currently used web servers. The final theoretical section addresses the topic of denial of service, discussing some types of currently known SDoS attacks, the tools that generate these attacks, and their shortcomings. Next chapter details the implementation of functionalities, which includes performance enhancements of the tool through the use of multiple processes. The developed tool features Slow Read, Slow Next, and Slow Drop attacks, as well as the ability to combine these attacks. This is followed by a description of how a local network of virtual machines was created for the purpose of testing the implemented tool. The final chapter presents the results and effectiveness of the tool in conducting SDDoS attacks against Apache and NGINX web servers in a local network.

Outsourcing of Print Services and Management of ICT Services
Kollár, Martin ; Hrůza, Tomáš (referee) ; Koch, Miloš (advisor)
In my thesis, I will focus on outsourcing the way it may be applied from global perspective. I will precisely define specific types of outsourcing, it`s versatility and summarize current trends in outsourcing business. Besides outsourcing, focus has also been put on managed service known as managed ICT services. Looking into these, particular interest is given to outsourcing of printing services and managed desktop services. As a result, deep dive into current situation of a concrete company was done, listing analysis of actual printing devices and desktop devices, ending with closing summary recommending the best way to implement new solution and smart ways of financing.

Fitness Map Application
Hrůza, Tomáš ; Drga, Jozef (referee) ; Rozman, Jaroslav (advisor)
As the world continues to evolve and expand, the need for modern solutions rapidly grows. Large portion of the population tends to keep track of their lifestyle which in turn provides an opportunity for companies to create many different fitness devices and applications. The goal of this bachelor's thesis is to provide a new kind of motivation to get out into the world, provided by yet another web application. However this application provides its user with motivation in the form of a minigame - the user travels through the world and the application then calculates the area he captures using a Voronoi diagram based on his route. Another feature the application provides is viewing your routes in a merged, averaged form. This comes in handy when the user would like to approximate his actual route over several different activities. The first part of this bachelor's thesis collects information about different commonly used fitness applications. Out of all those a web application called Strava was chosen as a base for collecting user data. The resulting web application connects to Strava using OAuth and retrieves routes the user has collected using the Strava mobile application. One of the last chapters focuses on describing the implementation details about used and created algorithms. It additionally contains description of scripts which were used to extract data out of OpenStreetMap database and calculate Voronoi regions based on them. To store and search through calculated regions, a MySQL database is used. The application is developed using modern frameworks and is heavily oriented around a comfortable user interface and responsive web design.
