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.

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.

The Project Proposal for Building of Research Center
Hortová, Šárka ; Truhlářová, Martina (referee) ; Doskočil, Radek (advisor)
This diploma thesis deals with creating a project proposal of the research center construction according to the required specifications by SEDOX Company Ltd. The theoretical part describes the basic knowledge and tools of a project management – analytical tools for evaluating the financial and time project costs, also risk analysis relating to competitiveness and maintaining on top of the market. The third part is devoted to the current situation of the development application market. There is the complete proposal of the research centre construction, using the tools according to the IPMA (International Project Management Association) that were described in the theoretical part. In conclusion I have presented my own solution suggestions, their benefits, project sustainability, return of the investment cost and also long-term prosperity.

Security analysis of network traffic using behavioral signatures
Barabas, Maroš ; Hujňák,, Petr (referee) ; Zelinka,, Ivan (referee) ; Hanáček, Petr (advisor)
This thesis focuses on description of the current state of research in the detection of network attacks and subsequently on the improvement of detection capabilities of specific attacks by establishing a formal definition of network metrics. These metrics approximate the progress of network connection and create a signature, based on behavioral characteristics of the analyzed connection. The aim of this work is not the prevention of ongoing attacks, or the response to these attacks. The emphasis is on the analysis of connections to maximize information obtained and definition of the basis of detection system that can minimize the size of data collected from the network, leaving the most important information for subsequent analysis. The main goal of this work is to create the concept of the detection system by using defined metrics for reduction of the network traffic to signatures with an emphasis on the behavioral aspects of the communication. Another goal is to increase the autonomy of the detection system by developing an expert knowledge of honeypot system, with the condition of independence to the technological aspects of analyzed data (e.g. encryption, protocols used, technology and environment). Defining the concept of honeypot system's expert knowledge in the role of the teacher of classification algorithms creates autonomy of the~system for the detection of unknown attacks. This concept also provides the possibility of independent learning (with no human intervention) based on the knowledge collected from attacks on these systems. The thesis describes the process of creating laboratory environment and experiments with the defined network connection signature using collected data and downloaded test database. The results are compared with the state of the art of the network detection systems and the benefits of the proposed approximation methods are highlighted.
