Measurement design in modern packet, transport, and access technologies
Galovič, Dominik ; Michálek, Jakub (referee) ; Škorpil, Vladislav (advisor)
The diploma thesis focuses on the capabilities of the VeEx VePAL Tx300s analyzer and network analysis. In the theoretical part, the thesis focuses on the most common tests used for analyzing network parameters of networks and its devices. Their principles, advantages, and disadvantages are described. The choice of the tests is deliberately selected to match the capabilities of the analyzer itself. Its basic functions are described in this diploma thesis. After understanding the functioning of individual tests and the analyzer itself, two laboratory tasks were created to familiarize potential students, for whom these tasks were designed, with the basic operation of the analyzer and to acquaint them with basic as well as advanced testing of network parameters, whether of active network elements or the laboratory network itself. An addition is the use of the VeEx VePAL tx300 analyzer, which was purchased previously, and the change of an already made laboratory task.

Analysis of horizontal transfer of genetic components using static network analysis
Labanava, Anastasiya ; Jurečková, Kateřina (referee) ; Schwarzerová, Jana (advisor)
The bachelor's thesis focuses on the issue of horizontal genetic elements transfer between bacteria of different strains and the software analysis implementation that enables horizontally transferred genes identification. The packages and tools used were tested on a dataset of bacterial genomes from several strains. The thesis’ theoretical part provides a detailed description of the genetic components transfer between bacteria and describes modern laboratory techniques that enable genome sequencing in various ways. In the practical part, the thesis deals with the preprocessing of genomic files to obtain suitable data for annotation. To detect the horizontal transfer of genetic elements between bacteria, a script is introduced, which organizes annotated bacteria to tables and searches for the same genes in their genomes that, under theoretical assumptions, were horizontally transferred. Furthermore, the gene transfer is visualized using tools that graphically represent phylogenetic relations between bacteria. In the final step, bacterial genomes are connected into networks, and based on their static analysis, a discussion is conducted on the results accuracy and the success of the proposed analysis.

Multiplatform Linux Sandbox for Analyzing IoT Malware
Uhříček, Daniel ; Burget, Radek (referee) ; Kolář, Dušan (advisor)
Analýza IoT malwaru je problematická zejména pro množství a rozlišnost architektur procesorů používaných IoT zařízeními. Práce shrnuje možnosti statické, dynamické a síťové analýzy Linuxového malwaru a hodnotí existující open source řešení oddělených běhových prostředí pro automatizovanou analýzu. Práce navrhuje modulární, rozšířitelný systém s~jednoduchými možnostmi nasazení, dostupnou API a webovým rozhraním. Výsledná implementace podporuje pět architektur a byla testována na vzorcích IoT malwaru.

Advanced Utilization of Network Analyzers
Novák, Přemek ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
This bachelor´s thesis consists of description of the laboratory network Cisco and any of its components. Furthermore, the possibility of network analysis according to the standards RFC 2544 and EtherSAM and description of the measurement using analyzer Vepal TX300, Fluke NTS II and Sunlite E1 used in lab reports. In the first task, the characteristics of network elements are analyzing. In the second task, parameters of Cisco network are examined and the third task is focused on the E1 frame.

Migration and Refactorization of Netfox Detective for .NET 5
Pokorný, Šimon ; Ryšavý, Ondřej (referee) ; Pluskal, Jan (advisor)
Every second, there are many attempts to attack various entities on the Internet. This is why high-quality, fast, and up-to-date tools are needed to easily analyze network traffic. Netfox Detective is one of such tools. Specifically, it is used for forensic analysis of network communication. The aim of this work is to migrate Netfox Detective to the newest version of .NET platform (.NET 5), including refactoring with respect to user experience and correct use of software design patterns. This thesis deals not only with the migration itself, but is listing common mistakes programmers make along with possible solutions to these mistakes. The chapters contain a detailed decision log that can help guide other developers to better solutions. Furthermore, the work deals with analysis and creation of unit tests and with correct use of tools for CI/CD. Fully migrated project is not the only output of this thesis. A development environment for the project has been prepared in GitLab and it is ready to be used.
