Phishing Webpage Detection using Machine Learning Methods
Polóni, Peter ; Poliakov, Daniel (referee) ; Hranický, Radek (advisor)
Phishingové stránky sú veľmi nebezpečnou hrozbou, čo znamená, že úspešná a spoľahlivá detekcia týchto stránok je veľmi doležitá. Tieto hrozby detekujem s využitím prístupu strojového učenia. Tento prístup je efektívny a dokáže odhaliť aj hrozby, s ktorými sa nikdy predtým nestretol. Ako dôveryhodné zdroje dát URL som využil OpenPhish a PhishTank. Z dôveryhodných URL som nazbieral HTML a JavaScript kód webových stránok. Zber dát som vykonal pomocou programu, ktorý som pre tento účel vytvoril. S využitím vektoru príznakov, ktorý sa skladá z 82 numerických príznakov, som vytvoril štyri klasifikátory. Následne som ich vyladil a experimentálne overil presnosť ich predikcií. Najpresnejší model je XGBoost klasifikátor, ktorý dosiahol vyváženú presnosť až 97.03% a FPR 2.22%, počas predikovania dát, ktoré nikdy predtým nevidel. Výsledky ukazujú, že tento prístup detekcie je schopný identifikovať phishingovú stránku aj v praxi. Toto som overil aj implementovaním webového rozšírenia pre prehliadač Chrome, ktoré detekuje phishigové stránky. Toto rozšírenie je vytvorené nad rámec zadania.

Home security system
Čada, Jan ; Burda, Karel (referee) ; Lattenberg, Ivo (advisor)
This master thesis deals with the design and implementation of a security system for a family house. It consists of a central control panel, a control keyboard and detectors connected using cables. The first part of the thesis discusses the electronic security and fire alarm systems, describing the individual elements of these systems and their different types. Magnetic contacts, fire detectors, sirens and a mains power supply with UPS function are selected from the current offer based on a comparison of parameters. In the next section, a block diagram of the whole system is designed. Raspberry Pi Pico development board with an RP2040 microcontroller is selected along with a GSM module SIM800L for SMS alarm notification and an Ethernet module with a Wiznet W5500 chip for the possibility of implementing a web interface. Schematics of the individual modules of the system are designed - for the central control panel, input module with PCF8574 circuit and two PCBs of the control keyboard module, which is equipped with a button keyboard with backlight, character LCD display type 1602 and proximity sensor VL53L0X for automatic lighting when person comes closer than a defined distance. PCBs are designed according to the schematics. Their manufacturing is then ordered, all components are mounted and the PCBs are placed in a 3D printed enclosure in the case of the control keyboard, and on the mounting plate of the metal cabinet in the case of the central control panel, according to the designed mounting plan. For the selected piezo sirens, covers are designed and 3D printed in the design of the selected Paradox NV5 motion sensors. In addition to the central control panel and the control keyboard, door and window contacts, fire detectors and sirens are installed in the house. The next part is dealing with the development of the control software for the central control panel and control keyboard in MicroPython language and the design of a custom communication protocol on the RS-485 bus for communication between the central control panel and control keyboard. Both control programs are based on the state machine principle, and their state diagrams are presented in the thesis. Part of the text is also focused on the development of the central control panel web interface and integration of the desinged system into the Home Assistant open-source automation system. The last part describes the activation and testing of the system in real conditions of a family house.

Web apps suporting education in computer graphics
Jalovecký, Denis ; Švento, Michal (referee) ; Rajmic, Pavel (advisor)
Master's Thesis focuses on creating three dynamic and interactive applications in JavaScript, serving as educational tools for courses centered around the creation and processing of image signals. The first application will represent a parametric curve in 3D space. The second application will explore barycentric coordinates of a 3D triangle, and the third will illustrate the Bayer filter in the context of digital photography creation.

Educational Application for Learning about Plants
Nedělová, Markéta ; Tesařová, Alena (referee) ; Hynek, Jiří (advisor)
This work focuses on the design and implementation of an interactive educational application that could help students master the learning of plant species through elements of gamification. To address this problem, a progressive web application was designed and implemented. This application was created in response to the requirements and needs identified during cooperation with the Primary School in Olešnice. It allows students to practice and expand their knowledge of plants through quizzes.

Interactive web application for displaying of rainfall maps
Soboňa, Jakub ; Kohout, David (referee) ; Bubniak, Milan (advisor)
Táto bakalárska práca sa zaoberá vytvorením interaktívnej webovej aplikácie pre zobrazenie zrážkových máp. Zrážkové mapy sú vytvorené z dát nameraných sieťou komerčných mikrovlnných spojov, preto sa teoretická časť zaoberá mikrovlnnými spojmi a oportunistickými meraniami zrážok. Frontend aplikácie je spravený použitím JavaScriptovej knižnice React spolu s HTML a CSS. Backend je spravený použitím Node.js a Express.js. Implementácia a funkcionalita tejto aplikácie je ukázaná v práci.

Client Server Application for the Creation of File Pages for the PČR
Terbr, Filip ; Beran, Vítězslav (referee) ; Rydlo, Štěpán (advisor)
The diploma thesis is devoted to the design and implementation of a system for editing photographic documentation of the Police of the Czech Republic. The work includes an analysis of currently used technologies, a design of the client application, a design of the server part of the system and a description of the implementation of the client and server parts of the system. The resulting implementation of the server part is written in JavaScript with support for the Express.JS framework, the resulting client application is written in JavaScript using the Electron framework.

Web Application for NS2 Training
Pavlosek, Václav ; Koutný, Martin (referee) ; Šimek, Milan (advisor)
There is information to my master's thesis which is called “Web application for NS2 training”. This application works after installation and its source codes are saved on applied CD. It is said about implement Network Simulator 2. It helps to realize simulation of nets and then author inserts information about them into web application. Registered web's visitor has possibility to insert project into application. The project contents information about simulation created in NS2. Web application can also visible detail of possible project which is approved of administrator. Then the visitor can sort projects, search entered expression or connect his contribution to discussion forum. Administrator can approve users projects in his part of application. It makes available for the others. He can also delete them from database. Theory about technologies which are used for implementation of this application. It is talked about web Apache server, database MySQL server and programmable PHP language. There is also mentioned information about security of web application included possible attacks on applications and their database. It is presented proposal of database which creates core of application. This proposal is depended on application requirements. Next chapters give to reader whole image about functionality of application. There are mentioned samples of final graphical image of application. This document also provides the shows of source codes for creating database tables.
