Nginx Web Server Security Weakness Detection Tool
Wagner, Michal ; Perešíni, Martin (referee) ; Křena, Bohuslav (advisor)
This thesis focuses on the security of the Nginx web server and its configuration options, with an emphasis on the reverse proxy server feature. It explores available alternatives to Nginx and security threats to reverse proxy servers. The thesis also delves into methods of detecting these security threats through penetration testing and conducts research on existing tools for detecting security vulnerabilities in reverse proxies. In the practical part, a tool is developed to demonstrate security attacks and detect vulnerabilities on the Nginx server. The functionality of the tool is validated in a suitable testing environment, and based on the gained experience, a technical specification is formulated for configuring the Nginx reverse proxy server to limit its susceptibility to attacks.

Cloud-Based Server for Robot Management
Jezerský, Matouš ; Kapinus, Michal (referee) ; Materna, Zdeněk (advisor)
The goal of this project is to make robots running the ROS platform, and the servers running on them, more accessible to the users, without the need of reconfiguration after a change of network or the need of direct VPN connection, as well as with the emphasis on minimal software requirements for both users and robots. The result is an open-source application, which provides that. The solution is a reverse proxy server, put inbetween the clients and the servers running on robots - Dispatcher. For connection between clients and robots, two OpenVPN networks are used, and as a secure user interface, the existing system RMS is used and extended with Dispatcher interface. Among other things, Dispatcher collects information about all connected robots so a summary can be displayed. This set of software tools therefore allows an authorized user to connect to robots in various networks, without the need of other client software apart of OpenVPN client and web browser.

Optimization of LAMP (linux/apache/mysql/php)
Kotlář, Pavel ; Fapšo, Michal (referee) ; Herout, Adam (advisor)
This work deals with topic of LAMP software bundle performance optimalization. Step by step, it tries to discover performance problems in all four parts of LAMP (in Linux, HTTP server Apache, MySQL database and PHP language interpreter). A model web application is created for these testing purposes. When a problem is found, a change in configuration files is done or a performance improving technology is applied to the corresponding part. A set of optimalization recommendations is compiled and verified on server running real web application.

Available Solutions for Server Clustering
Bílek, Václav ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
The goal of this master thesis is to analyze Open Source resources for loadbalancing and high availability, with aim on areas of its typical usage. These areas are particularly solutions of network infrastructure (routers, loadbalancers), generally network and internet services and parallel filesystems. Next part of this thesis is analysis of design, implementation and plans of subsequent advancement of an fast growing Internet project. The effect of this growth is necessity of solving scalability on all levels. The last part is performance analysis of individual loadbalancing methods in the Linux Virtual Server project.

Dynamic web pages
Kotlín, Jiří ; Kastl, Jan (advisor) ; Veselá, Bohumila (referee)
Serving dynamic web pages raises higher load of web servers and associated technologies. This can to some extent eliminate setting up reverse proxy with cache in front of the web server. The primary goal of this thesis is to implement this technique via presently most popular web server -- Apache. These Apache's proxy features were at first well tested and described, later practically applied in real LAMP software bundle enviroment (Linux, Apache, PHP, MySQL).
