Backend of a iOS Notification System
Mihál, Martin ; Rychlý, Marek (referee) ; Bartík, Vladimír (advisor)
The aim of this thesis is to design and implement backend of an iOS notification system, which can receive a notification through web request and send it to an iOS device. System sends notifications to iOS devices through the Apple notification server. System also provides a complete account management, which allows users to agregate notitifications into so-called services. These represent a user's software, which sends notifications. System communicates with the iOS application representing user through REST or GraphQL web service.

Implementation of Message Queue as a Service in Cloud Computing
Hanus, Tomáš ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
Thesis discusses about different ways of a communication between components of a distributed system. It describes a communication using a message exchange and at the same time talks about other alternatives. It adds details about various models of a message exchange, various message types and about various specifications as well. Commercial tools ActiveMQ, RabbitMQ and Kafka are presented. Special emphasis is placed on describing the way these tools exchange messages, scalability options and others. The web service is designed according to the described features. Its main purpose is management and monitoring of the tool by user choice and easy replacement of this tool with another one. Designed application is implemented using the Kotlin language for selected tool RabbitMQ. The implemented solution allows a simple exchange of messages through the REST api.

Information System for Accommodation Services
Bargl, Vojtěch ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
This bachelor thesis deals with microservice architecture. Main goals of this thesis is analysis of microservice architecture, comparison with monolith architecture and creation of a information system with the help of concepts revealed from the microservices architecture. This thesis reveals the volume of work that this architecture entails. The system is suitable for the management of apartments, users and reservations. This thesis describes the most important factors obtained from the analysis of this architecture, the process of specifying the domain of accommodation services and the development of the system itself with the help of the application of these concepts.

Genetic Algorithms - Implementation of Multiprocessing
Tuleja, Martin ; Ilgner, Petr (referee) ; Oujezský, Václav (advisor)
Genetic algorithms are modern algorithms intended to solve optimization problems. Inspiration originates in evolutionary principles in nature. Parallelization of genetic algorithms provides not only faster processing but also new and better solutions. Parallel genetic algorithms are also closer to real nature than their sequential counterparts. This paper describes the most used models of parallelization of genetic algorithms. Moreover, it provides the design and implementation in programming language Python. Finally, the implementation is verified in several test cases.

Radar Interface and Its Interconnection to Air Traffic Control System Simulation
Buchníčková, Tereza ; Ondřej, Karel (referee) ; Smrž, Pavel (advisor)
This thesis aims to create an application for training new air traffic control officers. The system is implemented as a JavaScript web application using the JQuery and Leaflet libraries. The server part is written in Python using the BlueSky library for air traffic simulation. The thesis presents a theoretical background and discussed the design and implementation of the system. The result is an application that offers to display current air traffic, or where the user, in the role of air traffic control officer, can practice communication with a pilot on simulated air traffic. The application allows the recording of voice communication and, in cooperation with an automatic speech recognition system, converts this communication into text displayed on the screen. In addition to the support of the training of air traffic operators, this application also serves as a demonstration of the results of the research groups KnoT and Speech from the Faculty of Information Technology, Brno University of Technology.

Design, Creation and Implementation of Software Applications in the Corporate Environment
Pacal, Václav ; Koch, Miloš (referee) ; Novák, Lukáš (advisor)
The thesis deals with the analysis of the current state, design and implementation of a web application in a corporate environment for processing and storing data from an application that does not use relational databases, but works with event-based data. In addition, the application allows the export and transformation of this data to an external database for an analytical application. The thesis includes an analysis of the tracking of data changes in the database and message brokers. In addition to the design and implementation, the final chapter discusses the economic evaluation of the thesis.

Queue Data Processing
Polívka, Tomáš ; Rychlý, Marek (referee) ; Bartík, Vladimír (advisor)
The idea of this bachelor thesis is to select the most suitable technology for queuing data processing. Using the selected technology, we will then implement the queuing solution in a currently running application. The final implementation compare with the existing solution which is based on database queuing.

Web application for generalizing SIEM correlation rules
Matušicová, Viktória ; Mikulec, Marek (referee) ; Safonov, Yehor (advisor)
The risk of attacks on companies by organized crime increases as technology advances. Attacks that focus on modifying data or gaining access to a company's network are constantly developed. The sophisticated nature of advanced threats distinguishes them from broad-based attacks that rely on automated scripts. However, organizations can mitigate this risk by utilizing a combination of appropriate tools. These include network flow monitoring, probes for detecting and preventing attacks, and Security Information and Event Management (SIEM) tools for correlating incidents and events. By leveraging these tools, suspicious behavior in the network can be identified, and measures can be taken to prevent and mitigate the impact of cyber attacks. The main contribution of this thesis is the development of a web application that serves as a general tool for managing correlation rules across various SIEM solutions. Through the use of this web application, publicly available Sigma rules can be managed and converted into target SIEM solutions. Users are given the ability to save these rules to their personal user section, alongside SIEM conversions and visual representations of technique coverage based on categorization by MITRE ATT@CK and LogSource of stored user rules. The theoretical part of the thesis comprises an analysis of security monitoring issues, an explanation of the benefits of the Sigma platform and an analysis of the web application. A use case model is defined, functional and non-functional requirements are specified to describe the resulting system. Additionally, the analysis of available tools for converting Sigma rules is performed. The practical portion of the thesis begins with a focus on the design of the web application, including the architecture of both the server-side and client-side components, as well as an explanation of the core functionalities. The resulting solution is then implemented, with detailed procedures for creating microservices, client-side development, and launching the web application. The final state of the project summarizes the result. The thesis concludes with a testing phase, the client side of the web application is evaluated through functional user interface screenshots. The thesis also includes a demonstration of the process for testing Sigma rules, which involves converting the rules using the web application and subsequently carrying out functional verification using the RSA NetWitness SIEM test solution.
