Web application for visualization and analysis of correlation rules deployed in cyberspace
Závišková, Hana ; Říha, Kamil (referee) ; Safonov, Yehor (advisor)
In a world of constantly evolving modern technologies, there is a growing need of developing cyber security strategies to protect digital infrastructures as the number of cyber attacks is rapidly increasing. The main goal of the bachelor thesis is to create a tool for visualizing correlation rules of SIEM systems. The tool is implemented as an extension to an existing web application and aims to allow a security expert or application user to explore user Sigma rules according to different criteria and based on different views. From a theoretical point of view, the bachelor’s thesis focuses on introducing the reader to the basics of cyber security in terms of the motivation for providing security, explaining the basic concepts necessary to understand the content of the thesis and analyzing the perspectives in which cyber attacks can be viewed. It also contains a description of selected cyber attacks, the selection of which is based on the statistics of cyber attacks on the Czech Republic for the first three quarters of the year 2023. This is followed by an explanation of the principles of detection and prevention of cyber incidents, technologies for ensuring protection in cyberspace, including the issue of log sources and platforms for detecting information about threats and the principles of cyber incident investigation. This is followed by an introduction to the legal regulation of cyber security, including a description of ENISA recommendations. The practical part of the bachelor thesis is further divided into four chapters. In the first part, an analysis of available web frameworks that can be used in application development and an analysis of the rule visualization methods used in two modern SIEM solutions were performed. The second phase focuses on the design of different views that can be used to provide a pleasant, intuitive and interactive environment for displaying user rules. The visualization designs include the components available in the D3.js library and working with the MITRE ATT&CK matrix. The second phase also includes the creation of a structure for the layout of the elements in the web application. The third phase is oriented towards approaching the actual implementation of the appropriate views that result from the analysis performed in the second phase. It also includes a description of the experimental environment in which the application was developed and how the data was obtained. The last phase focuses on testing the visual part of the application from the user’s perspective. The whole thesis finishes with a conclusion, which summarizes the results of the bachelor’s thesis, which have been achieved, and suggestions for improving the application in the future.

Control system for glue dispensing application model
Šimurda, Jan ; Hynčica, Ondřej (referee) ; Fiedler, Petr (advisor)
This thesis addresses the problematics of automated mini-doses application of the adhesive. In thesis are summarized the parameters and types of adhesives with regard to the suitability and the basic theory of bonding. At the same time are summarized the available technologies and methods of bonding. Part of the work is the analysis of requirements for automatic microdosing, in terms of management, delivery system, manipulator, mechanics, functional safety. It also includes the selection of suitable components. The thesis contains the development and description of the control software, visualization, data acquisition, management of robotic manipulator, functional safety logics and dispenser management. The outcome of the thesis is a functional device according to the proposed 3D model made of borrowed components on which algorithms are tested and functionality was verified. In the conclusions are described the complementary features ensuring the possibility of setting the device up in the industry.

3D model of Church of the Virgin Mary of the Snow in Velké Karlovice
Slováček, Jaroslav ; Hanzl, Vlastimil (referee) ; Bartoněk, Dalibor (advisor)
The thesis is focused on the creation process of the 3D model of Panna Marie Sněžná church in Velké Karlovice, which is based on geodetic measuring. The introduction part deals with the historical context, localization and general description of the object. Furthermore, there is the introduction of methods of a 3D model production. The majority of the work contains description of method utilized for 3D model creation and that was used by us. This model was created in AutoCAD 2018 program.

Bridge across the I/11 road
Macák, Jan ; Šrubař, Jiří (referee) ; Panáček, Josef (advisor)
This diploma thesis deals with a project of a road bridge. The bridge is located on a second class road S 7.5/50 and goes over a I/11 road and a local road crossing in Bystřice. Three options of the road bridge are conceived out of which the connected beam girder is chosen for further development. A calculation of the structural stability of the load-bearing construction, that includes time analysis of the construction work (i.e. particular phases of the construction), is added to the project. The structural stability calculation is assessed in accordance with valid European standards. Drawing documentation, a time schedule and 3D visualization of the road bridge is also attached to the diploma thesis.

Safety of small press model
Peňáz, Ondřej ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
The work deals with the safety of an air press model. After examining the standards to carry out risk assessment, changes are implemented to compliance with safety requirements. Safety inspection is made according to standard ČSN EN ISO 13489-1. A software SISTEMA was used for the control of safety requirements. Description of a software equipment by Rockwell Automation and design of the control program in RSLogix 5000 in ladder diagram is the part of the work. The control is also proposed by the visualization application FactoryTalk for the touch panel PanelView Plus 600.
