Design of laboratory exercises in the field of network programmability
Dubovyi, Dmytro ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
The aim of the graduation thesis is to evaluate the current development in the field of SDN and the possibility of programmability of SDN elements using the application programming interface. The first theoretical chapter describes the following: the basic architecture of SDN, the traffic within SDN between its individual layers, the communication protocols Southbound interface and Northbound interface. The second chapter of the thesis deals with the programmability of SDN elements with the help of API. The third theoretical chapter describes the current development in the field of SDN. The practical part of the thesis is devoted to creation of two laboratory tasks dealing with the programming of the SDN API. Laboratory tasks include BIG-IP programming from F5 Network and routers from Arista Network. Programming is done using Python via REST API for BIG-IP, or eAPI for Arista EOS. The Ansible setup tool is also used for the same purpose.

MITM Attack Automation Using Single-Board Solution
Podlesný, Šimon ; Letavay, Viliam (referee) ; Pluskal, Jan (advisor)
Thesis is focused on design of MiTM attack with use of modern approaches in IT infrastructure. Especially it's focused on how to simplify configuration of single-board computer for penetration testing purposes by creating scalable infrastructure for device configuration and control. Proposed solution allows the usage of complicated attacks by trained staff while not limiting users with experience in network security. While today, applications capable of MiTM attacks are monolithic and device-centric, proposed solution considers the device providing MiTM just as one part of the solution and also focuses on other problems like data exfiltration or hash cracking.

Ansible for Windows
Klíč, Jiří ; Očenášek, Pavel (referee) ; Trchalík, Roman (advisor)
The main purpose of this bachelor thesis is dealing with possibilities of automation of the computer management and acquisition of data about computers. This thesis focuses on automation of Windows-based computers managed by Linux operating system. The automation is performed by text user interface. It presents to the reader the used tool named Ansible and its components and usages. Here are discussed both methods of collecting of required data and their meaning and interpretation. Some data which are collected in this work are static, the rest of them use to change their values by time. There are also discussed possibilities how to manage the software equipment of the computer.

Cluster Management
Hlaváč Ďurán, Dominik ; Očenášek, Pavel (referee) ; Trchalík, Roman (advisor)
The bachelor thesis focuse on the design of a system for complex administration and monitoring server cluster based on the Red Hat Enterprise Linux/CentOS operating system using the Ansible tool. In the thesis there is a brief description of used technologies and issues of management of server cluster. The tool, that was implemented by us, provides preparation of the environment for system deployment, remote installation and configura- tion of applications, hardware registration, software and hardware system monitoring and much more. Consequently, there is a comparison of the resulting system with existing tools. Practical examples of the issue dealt with is also part of the thesis.

Continues Integration Support for Copr Build System
Klusoň, Martin ; Hruška, Martin (referee) ; Rogalewicz, Adam (advisor)
This thesis deals with implementation of continuous integration for build system Copr. The implementation uses framework Citool and its modules, which are already used for continuous integration of build system Koji. The outcome system can run the tests for the new package from the build system Copr and test it on virtual machine. This thesis shows way how to implement continuous integration for build system Copr.

Automatic verification of software packages with help of DNS
Sehnoutka, Martin ; Dvořák, Jan (referee) ; Jeřábek, Jan (advisor)
Tato diplomová práce se zabývá problémem bezpečné distribuce software. Je navrženo zlepšení s pomocí doménového systému, který je použit pro uložení verifikačních klíčů, potřebných pro ověření integrity balíků stáhnutých pomocí správce balíků. Navíc je navržena rozšířená verze, které se zabývá zabezpečením metadat repositářů. Obě verze jsou implementovány v jazyce Python a integrovány do správce balíků dnf. Tato implementace je otestována ve virtuálním prostředí, diskutována a zhodnocena z hlediska způsobené zátěže.

Management and Monitoring System for Computer Lab
Kudláček, Marek ; Zeman, Kryštof (referee) ; Mašek, Pavel (advisor)
This master's thesis deals with a system for PC mass management and monitoring. There is a brief description of Puppet, Chef and Ansible, which are tools enabling this functionality. The overall system issues are solved by Ansible. This thesis also includes a script created for a classroom’s remote management according to a beforehand fixed assignment. The system enables remote installation and configuration of applications, creation of users, editing the files, update of the system and many more. A web application was created for this system. Through this application, the system can be controlled via web browser, both from local and public network. Practical examples of the issue dealt with is also part of the thesis.
