Heřman, Kristián ; Snášel, Daniel (oponent) ; Malinka, Kamil (vedoucí práce)
The aim of this thesis was to design and create an educational application for Czech sign language, which will be used as a application for learning and practicing vocabulary. The application uses the Flask web framework for the server side, jinja2 for HTML templates and the Socket.IO library for real-time communication between client and server. The graphical user interface was designed using Bootstrap and JavaScript. The application was user tested.

Blockchain Resistant to Quantum Attack
Ľaš, Michal ; Perešíni, Martin (oponent) ; Malinka, Kamil (vedoucí práce)
The development of quantum computers presents new opportunities but also introduces a threat by compromising currently used cryptographic algorithms. This threat significantly impacts blockchain technology, which relies on various cryptographic principles. The objective of this work is to design and implement a blockchain that incorporates new post-quantum cryptographic algorithms resistant to attacks performed by quantum computers. The main part of my solution involves analyzing blockchain components vulnerable to quantum attacks, selecting appropriate post-quantum algorithms, and subsequently implementing them within the blockchain. The result of this work is an overview of blockchain vulnerabilities and their solutions in the post-quantum era. Additionally, the implemented solution compares the performance of multiple post-quantum and currently used algorithms. The results show that post-quantum cryptography can have a significant impact on blockchain performance. However, post-quantum blockchains will still be usable, and they will withstand the era of quantum computers.

Advanced Web-based Tool for Managing Security Correlation Rules and Cybersecurity Responses
Hemza, Martin ; Firc, Anton (oponent) ; Malinka, Kamil (vedoucí práce)
The aim of this bachelor thesis is to develop an advanced web-based tool for managing security correlation rules and cybersecurity responses, focusing on SIEM and SOAR technologies. The reason for this thesis is the lack of a standardized resource format for these technologies. As part of this work, these formats were found and a web tool was created to manage and design them. The interface for managing SOAR scenarios includes a visualization in the form of a decision tree. The application uses a microservices architecture with integration of the Git versioning system. Testing included a description of an attack and the use of the developed tool. The created tool allows security analysts to quickly design and manage resources for detecting and responding to security threats.

Impact of AI Tools on Code Quality and Security
Vinarčík, Peter ; Holop, Patrik (oponent) ; Malinka, Kamil (vedoucí práce)
This work presents a newly developed application that is able to perform fully automated large-scale research for evaluating the safety and quality of AI-generated code. Also, a new way of evaluating the safety of AI-generated code has been presented, utilizing MITRE's methodology in combination with SAST tools performing static analysis on the code. In addition, the application is enhanced with an improved AI chatbot whose output is enhanced with the results of static analysis at generation time. The user inputs a dataset of prompts into the application, and if code with a vulnerability has been generated for a particular prompt, that vulnerability is scored by the established methodology, and the user is informed not only that the code is vulnerable, but how vulnerable it is. As part of the solution, large-scale, pilot testing of popular AIs, such as ChatGPT-4 or Gemini, is performed over a dataset of prompts using the new application, in contrast to existing studies. The results showed the dominance of ChatGPT-4 running on the GPT-4 model, over the other AIs tested.

Photo Livening Application
Bobola, Adrián ; Šalko, Milan (oponent) ; Malinka, Kamil (vedoucí práce)
The goal of this work is to create a web application for animating static photographs. The application allows users to animate their portraits and group photos. Users can upload their own motion, which they want to use, and the application will use it to animate a selected part of the uploaded photo. The faces in the photos are automatically detected, while users have the option of manually marking faces in a given photo. The application supports recording custom motion from a video file or directly from a webcam. The server-side of the application is implemented in Python using the Django framework. The client-side of the application utilizes JavaScript and the React framework. Communication between the client and the server is facilitated via REST API. The thesis also provides an overview of existing tools of similar types, compares them, and discusses identified shortcomings. Additionally, the thesis explains the techniques and principles used to animate static photographs.

Design Better Content Development Process for SCAP Standards
Beňas, Petr ; Malinka, Kamil (oponent) ; Barabas, Maroš (vedoucí práce)
The aim of this work is to study and describe the SCAP security standards in a simple way with focus on the XCCDF and OVAL formats. State-of-the-art editors and content development approaches are described and their benefits together with shortcomings are identified. Based on the obtained knowledge, a new content editor design is proposed to minimize the shortcomings of the known approaches. Implementation and testing of the proposed editor are described.

Decentralizovaný autentizační systém založený na blockchainu
Mračna, Štefan ; Malinka, Kamil (oponent) ; Januš, Filip (vedoucí práce)
Tato práce se zabývá zavedením blockchainu do autentizačního systému, konkrétně do biometrického autentizačního systému pro otevírání dveří. Práce analyzuje různé blockchainové technologie a autentizační systémy a určuje, které technologie jsou pro tyto účely vhodné. Porovnává také centralizované a decentralizované autentizační systémy. Na základě analýzy se navrhuje decentralizovaný autentizační systém se zabudovaným blockchainem a zjednodušená verze systému, kde individuální zařízení jsou reprezentovány procesy, se implementuje. Nad tímto systémem je vytvořen program simulující provoz. Nakonec se provádí testování výkonnosti, bezpečnosti, spolehlivosti a paměťové náročnosti systému v různých podmínkách.

Analýza a návrh změn informačního systému MEDIMED
Lebeda, Martin ; Malinka,, Kamil (oponent) ; Neuwirth, Bernard (vedoucí práce)
Tato práce pojednává o modifikaci řešení projektu Medimed, který přestal vyhovovat požadavkům na něj kladených. V první části práce jsou vymezeny hlavní cíle, dílčí cíle a metody k jejich dosažení. V druhé části je zpracována teorie, která je potřebná pro pochopení dané problematiky. V praktické části, která navazuje na teorii je vyhotovena analýza současného stavu SWOT a modifikovanou HOS-8 analýzou, jejichž výsledky jsou následně analyzovány. V další části jsou prezentovány vlastní návrhy řešení. V závěru jsou shrnuty veškeré návrhy řešení a poznatky, kterých bylo touto prací dosaženo.

System for Race Car Parameterization
Tiszai, Patrik ; Stančíková, Ivana (oponent) ; Malinka, Kamil (vedoucí práce)
The work aims to design and implement an application for creating the configuration of messages and device filters in the CAN-bus for the school development team TU Brno Racing. Above all, the application should streamline and reduce the error rate when creating new configurations. For successful development, a requirements analysis was first performed in the team and subsequent design and implementation. The result is a functional web application that is tested for the usability of the configuration and user interface.

Server pro správu klíčů v prostředí vSphere 7.0
Dejmal, David ; Homoliak, Ivan (oponent) ; Malinka, Kamil (vedoucí práce)
Cílem této práce je vytvořit funkční server pro správu klíčů (Key Managment server - KMS) se základní funkcionalitou pro platformu vSphere 7.0. Ten by měl komunikovat s vCenter a dohromady poskytovat funkci na šifrování jednotlivých virtuální strojů. Komerční řešení v této oblasti jsou velmi drahá, a proto vyvstala otázka, zda lze celý server implementovat pomocí volně dostupných nástrojů.Jelikož vCenter používá ke komunikaci s KMS veřejně dostupný protokol KMIP, ukázalo se, že to lze. Výsledná implementace je založena na operačním systému Ubuntu 20.04. Pro aplikační logiku byla použita knihovna PyKMIP pro python 3.9 a jako úložiště bylo použito ETCD. Pro spojení aplikace a úložiště bylo potřeba vytvořit vlastní modul.Pro veškerou potřebnou konfiguraci včetně instalace byly vytvořeny Bash skripty. Celkový výsledek je plně funkční a během testování nebyly nalezeny žádné nedostatky. Na práci probíhala spolupráce se společností Master Internet, s.r.o.
