Fast Processing of Application-Layer Protocols
Bárta, Stanislav ; Martínek, Tomáš (referee) ; Polčák, Libor (advisor)
This master's thesis describes the design and implementation of system for processing application protocols in high-speed networks using the concept of Software Defined Monitoring. The proposed solution benefits from hardware accelerated network card performing pre-processing of network traffic based on the feedback from monitoring applications. The proposed system performs pre-processing and filtering of network traffic which is handed afterwards passed to application modules. Application modules process application protocols and generate metadata that describe network traffic. Pre-processing consists of parsing of network protocols up to the transport layer, TCP reassembling and forwarding packet flow only to modules that are looking for a given network traffic. The proposed system closely links intercept related information internal interception function (IRI-IIF) and content of communication internal interception function (CC-IIF) to minimize the performing of duplicate operations and increase the efficiency of the system.

Additional Options of the ECCAIRS capabilities at national level
Durchan, Vladimír ; Hodaň, Viktor (referee) ; Chlebek, Jiří (advisor)
The focus of this diploma thesis is a development of a proposal for the modification of the reporting mandatory and voluntary occurrances on the national basis. In the first part of this thesis is describtion database system ECCAIRS and also describtion of the legislation which relates to the reporting of occurrances, specifically Regulation (EU) No 376/2014 of the European Parliament and of the Council. Second part of this diploma thesis is about the description of the proposed solutions to improve reporting system of occurrances. Second part also includes creation of the form for reporting occurrances.

Hardware cryptographic modules for LAN security
Loutocký, Tomáš ; Lambertová, Petra (referee) ; Zeman, Václav (advisor)
The thesis deal with the problems of virtual private network (VPN). The first part of the thesis is focused on the description of the basic terms of computer security which are useful for better understanding the other parts. There is a description of VPN technology and its separation of VPN by various aspects in the second part of the thesis. The next chapter is dedicated to the description of realization of VPN by using IPSec. There is shown how to secure laboratory network by using of the products of the Safenet Company in the practical part of the thesis. There are also stated the modular techniques how to use products in the network in practical part. Some of the modular techniques describe security weaknesses of the products which are possible to exploit in the laboratory network and they also describe the ways how to protect them against misusage.

Rationalisation of manipulation shop
Vičar, Miroslav ; Neužil, Karel (referee) ; Hlavenka, Bohumil (advisor)
The aim of this thesis is to reach a distinctive rationalization of the production and assembling plant of Cargo Van Brno company. In the project of new lay-out of the production area were all restrictions given by management of the company and by owner of the property strictly met. Technological changes of the process plan and investments suggestions are determined by the company's strategic plan.

Security and Privacy in IoT
Utěkal, Josef ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
The bachelor's thesis deals with the topic of security and privacy in the field of Internet of Things (IoT), for which resource constrained devices are typical. It is very important to find a suitable operating system that, in addition to low computational requirements, would also offer the desired functionality for these constrained IoT devices, such as real-time capabilities. OS RIOT seems to be the one for IoT. It enables you to run applications written in C language on any supported hardware -- in this bachelor's thesis specifically on Arduino Uno and Arduino Due. The thesis also describes several cryptographic libraries that are supported by OS RIOT. The aim is to implement selected cryptographic libraries and measure their computational and memory requirements on both Arduino devices. This is preceded by a theoretical and practical familiarization with OS RIOT, which is realized by creating the first project, and measuring the computational complexity of each cryptographic function of the WolfSSL library on the Raspberry Pi 4 Model B.

Bezpečný model elektronického obchodování a jeho ekonomické
Fotijev, Pavel ; Smejkal, Vladimír (advisor)
The purpose of the presented dissertation thesis is to contribute to the development of the theory of electronic commerce in complex conditions of „network economy“ by the partial consolidation and integration of the highly fragmented existing knowledge and ideas, i.e. to offer more compact conceptual framework, based on research of the current state of knowledge and situation in the conditions of the Czech Republic. The thesis is focused on the contemporary theoretical knowledge analysis from the areas of interest concerning the electronic commerce security, used models of electronic shops and evaluation of its economic aspects, which this type of business bears. Next contribution is unification of this knowledge and creation of the conceptual base for the ongoing recognition and theory building related to electronic commerce. The work is also focused on the area of electronic cash, possible solution of some diversifications in payment transactions. On the practical level the author attempted to narrow the knowledge “gap” in the empirical cognition of the doctoral thesis issues concerning the effectiveness of electronic commerce and generally e-commerce applications. Proposed return on investment calculation methodology applied to e-commerce area may help managers making decisions in investing to these projects.

Stabilizing systems of passenger cars
Odehnal, Jakub ; Vopařil, Jan (referee) ; Kučera, Pavel (advisor)
This Bachelor’s thesis describes basic stabilizing systems of passenger cars. These systems are correcting driving the cars and improve safety of the traffic. The main systems described in this thesis are ABS, ASR and ESP. There are also summarized some other assistant systems. In the end there is also view of various individual car companies and their theories of stabilizing of cars.
