Design and implementation of network collector
Bošeľa, Jaroslav ; Horváth, Tomáš (referee) ; Oujezský, Václav (advisor)
This master’s thesis deals with description of information protocol of network flow, mainly definition of Cisco NetFlow version 9. Describes it’s features, message format and attributes of transmitted data. The thesis is primarly focused onto NetFlow v9 transmitted template, which defines fileds and data in consecutive data flow. The essence of the thesis consists in implementation of simple NetFlow v9 parser, which has been programmed in Python prog.language, it’s tests of captured UDP data from file and port capture testing on development server in lab. There is a possibility of saving captured and parsed data into prepared database within implementation as output from capturing.

Analysis of Wi-Fi traffic
Bakó, Zdeněk ; Pospíšil, Ondřej (referee) ; Pospíšil, Jan (advisor)
This bachelor thesis deals with the capture and analysis of wireless traffic of Wi-Fi networks. The aim of this work is to describe the possibilities of capturing and analyzing the operation of Wi-Fi networks. It describes the IEEE 802.11 standard, its features such as architecture and current standards. A selection of a suitable router is performed on which traffic capture and analysis is performed. Some open-source firmware for routers is compared and the most suitable one is selected. Tools for capturing and analyzing Wi-Fi network traffic are compared and described. The differences between the promiscuous and monitoring capture mode and their possibilities of use are described. Finally, there are described options for analyzing captured 802.11 frames.

Rule-Driven Protocol Analyzer
Jurnečka, Peter ; Zbořil, František (referee) ; Hanáček, Petr (advisor)
The master Thesis deals with an overview of issues necessary for design of custom network analyzer. Describes the existing solutions, provides the theoretical background needed for design of custom analyzer and describes the structure of implemented system. A separate part of the work is devoted to the specification of Metamodel used to modeling of communication protocols and compiler of models modeled with the Metamodel.
