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.

Interactive graphical environment for visualization of penetration testing
Klampár, Roman ; Martinásek, Zdeněk (referee) ; Lieskovan, Tomáš (advisor)
This thesis deals with the design, development and implementation of an interactive graphical environment to support penetration testing. The theoretical part describes the basic concepts of penetration testing, introduces the Penterep platform and the technologies used in the development, such as Vue 3, TypeScript and D3.js. The practical part focuses on the design of the data structure and architecture, as well as the implementation of the network graph with interactivity including drag and drop, zoom and pan. The implemented solution allows manipulation of the graph and its data, making it possible to change the graph structure. The thesis resulted in a package designed for flexible integration into existing projects such as the Penterep platform, into which the solution was also integrated. The thesis also analyses the performance of graph rendering using HTML5 Canvas and SVG. Rendering time, FPS and memory usage for different sizes of graphs were monitored during testing. The results show that HTML5 Canvas achieves better performance for larger amount of data. The aim of this work is to increase the efficiency of penetration testing, reduce the time consumption and simplify the necessary processes compared to the currently available tools.

Interactive Web Application for Design Space Exploration
Slávik, Denis ; Sekanina, Lukáš (referee) ; Vašíček, Zdeněk (advisor)
The desire of this thesis is to design and implement an interactive web interface that will allow users to select from a library of thousands of implementations of approximate adders and multipliers for circuit design and benchmarking, developed by Evolvable Hardware Group (EHW) from the Faculty of Information Technology at the Brno University of Technology. We will find out about the web technologies used for this thesis. Also, we will find a chapter devoted to designing a suitable user interface and an efficient algorithm to process and visualize several thousand implementations.

A Tool for Building CEG Graphs
Mutňanský, Filip ; Češka, Milan (referee) ; Smrčka, Aleš (advisor)
Cause-effect graphing is one of approaches to requirement-based testing. Cause-effect graphs (CEG) are used to visualize logic relations among requirements and to fill in a decision table to form test cases. The goal of this bachelor's thesis is to design and implement a tool for creating and manipulating with CEG graphs. The developed tool is implemented as a single-page web application. The manipulation with CEG is possible via graphical user interface and/or via text-based specification in a CEG specific language. Moreover, the tool uses logic solver to ease a user with creation of the decision table.

Graphical Visualization of Incident Handling
Markovičová, Veronika ; Holkovič, Martin (referee) ; Hynek, Jiří (advisor)
This bachelor thesis describes the proposal and implementation of components that visualize data on incidents and their states. These components aims to create a clear visualization of incidents and their states that would facilitate the search for information on incidents and thus streamlining their work. One of the components created shows a detailed description of individual states of incident. The second created component shows either one or more incidents as the sequence of their states on the timeline. As a suitable tool for visualization and demonstration of created components, dashboard has been chosen. Components were consulted and tested with Flowmon.
