Communication infrastructure virtualization platform
Stodůlka, Tomáš ; Martinásek, Zdeněk (referee) ; Uher, Václav (advisor)
The thesis deals with selection of infrastructure virtualization platform focusing on containerization with sandboxing support and with following examination of its difculty. The work begins with an explanation of the basic technologies such as: virtualization, cloud computing and containerization, along with their representatives, that mediate the technology. A special scope is defned for cloud computing platforms: Kubernetes, OpenStack and OpenShift. Futhermore, the most suitable platform is selected and deployed using own technique so that it fullflls all the conditions specifed by thesis supervisor. Within the difculty testing of the selected platform, there are created scripts (mainly in the Bash language) for scanning system load, creating scenarios, stress testing and automation.

Virtualization of energy infrastructure
Hraboš, Šimon ; Stodůlka, Tomáš (referee) ; Lieskovan, Tomáš (advisor)
This work describes the virtualization process, virtualization tools and virtualization automation. The work also deals with the description of energy infrastructure, KYPO cyber range platform and DLMS/COSEM protocol used in energy. The practical part deals with the virtualization of energy infrastructure using OpenStack and KYPO cyber range platforms. A virtual environment was created using Vagrant application. The OpenStack and KYPO cyber range platforms were subsequently installed in this environment. Next, a sandbox definition was created. The sandbox definition creates a scenario with an energy infrastructure using KYPO platform. The functionality of the energy infrastructure was verified using the Gurux DLMS library.

Routing principles in data networks
Stodůlka, Tomáš ; Burda, Karel (referee) ; Novotný, Vít (advisor)
This bachelor thesis deals with the problem of routing in data networks. The theoretical part defines general options of connections between two nodes. Furthermore, the principles of switching within a single network and routing between the networks are described. Another part of thesis focuses on the routing methods in terms of static or dynamic enrolment into the routing table. In the practical part have been designed and realized a structure and topology of laboratory exercise for subject Architecture of networks.

Cybersecurity game in OpenStack platform
Huška, Luděk ; Lieskovan, Tomáš (referee) ; Stodůlka, Tomáš (advisor)
The bachelor thesis is about creation of the cybernetic game on the OpenStack platform. The work starts with an explanation of necessary knowledge like: Informational cybernetic and computer security, security threats, and testing of the overall security. In the practical part, there is created a cyber game that focus on exploitation and basic security vulnerabilities. The next part involves analysis ongoing complexity of hardware resources like RAM, CPU, disc, etc. In the end, there is a guideline for a lab exercise, which is made for students and professors or teachers both separated.

Jump server preparation and implementation for game scenarios in Cyber Arena
Komárek, Ladislav ; Šeda, Pavel (referee) ; Stodůlka, Tomáš (advisor)
Bachelor's thesis deals with the problematics of the containerization and virtualization. Thesis focuses on the OpenStack platform and the creation of a Jump server. The main purpose of the thesis is to create a Jump server with the SSH connection to the OpenStack instances. Thesis is divided into three parts - theoretical and practical, which has two parts. The analysis of virtualization and containerization possibilities for Jump server is included in the theoretical part of the paper. Description of the OpenStack platform and its functions is also contained in the theoretical part. Based on the theoretical analysis, a~Jump server was created in second and third part. After manually verifying the functionality of the Jump server, its creation was automated on the Openstack platform.

Automation of Cyber Arena backup and recovery processes in Ansible AWX
Fišarová, Veronika ; Lieskovan, Tomáš (referee) ; Stodůlka, Tomáš (advisor)
The master thesis focuses on the cyber range Cyber Arena and the OpenStack cloud platform, on which the Cyber Arena is built. The theoretical part of the work is dedicated to three essential technologies used in the construction of cyber ranges. These technologies are virtualization, containerization, and cloud computing. In the next part, the analysis focuses on the OpenStack platform and its essence in the Cyber Arena. This is followed by an introduction to the Ansible AWX automation platform, which acts as an intermediary between the Cyber Arena and OpenStack. The last part of the theory is dedicated to the issues of backups and recovery of OpenStack with the aim of improving the life cycle of the Cyber Arena. In the practical part, the creation of a development environment is described, consisting of the OpenStack platform and the AWX platform, in such a way as to best match the environment with the Cyber Arena. In this environment, an Ansible project is then implemented, which automates the creation of backups and subsequent recovery of the main OpenStack services. The project is implemented in such a way that the processes are transferable to new versions of OpenStack while maintaining the same deployment method.

Start Building Your Own Cyber Range – Cyber Arena
Stodulka, Tomas
The research deals with the importance of education against cyber crimes in today’s world.One of the solutions is through so-called cyber ranges. First two chapters briefly explain the currentproblematic and present some representatives of cyber ranges. The work continues by stress testingof the selected cloud computing platform that is the most suitable for cyber range purposes. Based onthe results, servers/devices are purchased, which form the basis of the future Cyber Arena in BUT
