Platform for Cryptocurrency Address Collection
Bambuch, Vladislav ; Pluskal, Jan (referee) ; Veselý, Vladimír (advisor)
Cílem této práce je vytvořit platformu pro sběr a zobrazování metadat o kryptoměnových adresách z veřejného i temného webu. K dosažení tohoto cíle jsem použil technologie zpracování webu napsané v PHP. Komplikace doprovázející automatické zpracování webových stránek byly vyřešeny techonologí Apache Kafka a jejími schopnosti škálování procesů. Modularita platformy byla dosažena pomocí architektury microservices a Docker containerization. Práce umožňuje jedinečný způsob, jak hledat potenciální kriminální aktivity, které se odehrály mimo rámec blockchain, pomocí webové aplikace pro správu platformy a vyhledávání v extrahovaných datech. Vytvořená platforma zjednodušuje přidávání nových, na sobě nezávislých modulů, kde Apache Kafka zprostředkovává komunikaci mezi nimi. Výsledek této práce může být použit pro detekci a prevenci kybernetické kriminality. Uživatelé tohoto systému mohou být orgány činné v trestním řízení nebo ostatní činitelé a uživatelé, zajímající se o reputaci a kreditibilitu kryptoměnových adres.
Infrastructure for Testing and Deployment of the Real­-Time Localization Platform
Ormoš, Michal ; Pluskal, Jan (referee) ; Veselý, Vladimír (advisor)
Táto práca je prípadovou štúdiou postupného vývoja a nasadzovania lokačného softwaru v reálnom čase. Cieľom tejto práce je zrýchliť tento proces. Zvolený problém bol vyriešený s konvenčnými testovacími nastrojmi, vlastným nástrojom pre generovanie sieťovej prevádzky lokalizačnej platformy a nástrojmi CI/CD Gitlab. Prínosom tejto práce je zrýchlenie vývoja, zaručenie kvality vyvijaného softwaru a predstavenie spôsobu ako platformu pre lokalizáciu v reálnom čase testovať.
Control of External Devices on macOS to Prevent Data Leaks
Zuzelka, Jozef ; Veselý, Vladimír (referee) ; Pluskal, Jan (advisor)
Práca sa zaoberá problematikou kontroly a blokovania externých zariadení v operačnom systéme Apple macOS za účelom ochrany pred únikom citlivých dát. Implementované riešenie ukazuje zvolené prístupy pre blokovanie externých a cloudových diskov. Pre blokovanie USB diskov bol použitý DiskAbitration framework, čo je najvodnejšie riešenie tohto typu úlohy. Avšak cloudové disky sú v skutočnosti synchronizované zložky a úlohu nehrajú ovládače ani strom pripojených zariadení. Ku kontrole operácií v cloudových diskoch bol použitý Endpoint Security framework. Aktuálne podporovaní cloudový poskytovatelia sú iCloud a Dropbox a prístup k nim môže byť obmedzený úplne alebo iba na čítanie. Schopnosť synchronizácie vzdialenýh zmien bola zachovaná avšak v prípade Dropboxu si to žiada nepoužívať ich aplikáciu na správu súborov.
The System for Collection and Analysis of Cryptocurrency Exchange Rates
Čaládi, Filip ; Pluskal, Jan (referee) ; Veselý, Vladimír (advisor)
Táto bakalárska práca je zameraná na kryptomeny, kryptomenové zmenárne a spôsoby cenotvorby na nich. Cieľom tohoto projektu je zber aktuálnych a historických dát o zmenárenských kurzoch, z dostupných zdrojov, zameraných na kryptomeny a Fiat peniaze. Zozbierané dáta su uložené v štruktúrovanej databáze s ohľadom na efektivitu a správu pamate. Navrhovaný systém, ktorý je schopný popísané dáta zozbierať, poskytuje všetky dostupné informácie vo forme REST API alebo webovej aplikácie a je nasadený v docker kontajneri. Validitu takéhoto systému som odtestoval výkonnostným testovaním modulu zodpovedného za zbieranie dát a implementovaním jednotkových testov pre každú časť systému.
Security Analysis of Home IoT Network
Čikel, Tomáš ; Jeřábek, Kamil (referee) ; Pluskal, Jan (advisor)
This work focuses on the issue of the  security in home IoT network. Specifically, it focuses on the security issues of commercial IoT devices and their automation systems. In the work itself, it was firstly analyzed and identified specific threats specific for our network. To address these threats, the original automation systems and firmware on the devices were replaced by open-source implementations that were configured to address discovered threats. Although, there are still several security issues in a network with an open-source implementation, a large part of the security issues which were discovered has been eliminated.  The results of this work allows to configure a home IoT network using an opens-source automation system and firmware and proves that such a network is more secure than the network where the original factory-supplied automation systems and firmware on devices are used.
DotVVM to Accelerated Mobile Pages Transpiler
Tichý, Michal ; Polčák, Libor (referee) ; Pluskal, Jan (advisor)
This thesis proposes an extension to the DotVVM web framework that adds support for conversion of DotVVM pages into AMP pages. This thesis describes the current status and inner workings of DotVVM and AMP. The thesis contains an overview of the advantages and disadvantages of both technologies. Second part of this thesis describes implementation of DotVVM.AMP. Final part of this thesis shows integration of DotVVM.AMP into an existing DotVVM application.
.NET's LINQ Optimization
Šerý, Daniel ; Ryšavý, Ondřej (referee) ; Pluskal, Jan (advisor)
This thesis deals with LINQ (Language integrated query) and investigates possibilities of its implementation and optimization in C# language. Method of rewriting of query to procedural code is chosen and implemented. The goal is to provide a LINQ that can be used in code with the need for high speed.          Regarding the program created for rewriting LINQ queries, the performance of most operators has been increased by 1.2x to 20x of System.Linq speed depending of rewritten algorithm, data source and provided information to rewriting program.
Rest API for Bitcoin Network Querying
Žigo, Tomáš ; Veselý, Vladimír (referee) ; Pluskal, Jan (advisor)
This bachelor's thesis solves issues of Bitcoin network transformed data processing. The main aim of this thesis is to describe the details of Bitcoin network cryptocurrency principles and subsequently create an application which is able to process and allow access to historical data as well as actual data in the network. The solution was focused on fast synchronization and the ability to respond to requests in the shortest possible time. The problem was implemented using the NoSQL database system Cassandra with database import strategy where some data fields are updated  only on request. Created solution is mostly able to compete with currently available tools.
Multiplatform Mobile Beekeeping Diary
Drábek, Petr ; Koutenský, Michal (referee) ; Pluskal, Jan (advisor)
The aim of this work is to create a transparent and intuitive mobile application replacing the classic paper recording of data about bee colonies for beekeepers. Furthermore, to provide the possibility of linking this application to the hive scale for even greater insight into bee colonies. The application is developed on Xamarin platform for Android and iOS. The result of this work is to help beekeepers to work with bees, store their data in a database and enable them to work with them on different devices. Provide the beekeeper with an upto-date overview of their apiaries, colonies and hives, as well as statistics from this data. 
Network Forensic Analytical Web-Based Platform
Ambrož, Tomáš ; Veselý, Vladimír (referee) ; Pluskal, Jan (advisor)
At present a big part of communication passes off through computer network. Amount of the communication magnifys every year. It has a consequence that claims on computing power raise. The procedure of processsing of the communication for forensic purposes pays off to parallel for the purpose of increase of computing power. Research group NES@FIT created an instrument Netfox Detective in one of its projects. From this instument it is planed to create a distibuted system for the processing of intercepted communication for the purpose of forensic analysis. Interface is one of parts with the help of its the distributed system will be operated. In my theses I will concern with the creation of the web interface for the instument Netfox Detective which is a desktop application presently. Web interface use, after little modifications, for paralleled version of application. Web interface will mediate the same informations as the desktop version. For the obtaining of informations for forensic analysis it will use framework Netfox Framework identically as the desktop version. Advantage of web interface compared to the desktop version is that user who approach to web interface need device with web browser. It means that user can work whichever operation system.
