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.

Dluhoš, Jakub ; Šplíchal, Miroslav (referee) ; Chlebek, Jiří (advisor)
DLUHOS, J. Effect of the human factor on small aircraft accident. Brno: Brno University of Technology, Faculty of Mechanical Engineering, 2013. 90 s. Supervisor Ing. Jiří Chlebek, Ph.D. The Master’s thesis focuses on the safety of civil aviation, which is in 80% of the accidents caused by Human Factor, Human Error or just Pilot Error. The main goal of this Master’s thesis is evaluation and assessment of the causes of aircraft accidents of general civil aviations operations of the Czech Republic. In the practical part of the Master’s thesis were analyzed accidents of aircrafts in the category with maximum take of mass to 2250 kg and ultra light aircrafts incurred in the Czech Republic from 2006 to 2012. In the conclusion were analyzed main causes of the aircraft accidents and were proposed further measures to reduced accidents caused by Human Factor.

Novák, Marek ; Dvořák, Jaromír (referee) ; Píška, Miroslav (advisor)
The goal of this master thesis was increase production efficiency of turning machine TORNOS MultiDECO 20/6, which are unique in the Czech Republic by their contruction. Based on data analyzed has been found few areas, where are possible improve operations to increase production efficiency. For improving production efficiency has been implemented several real devices on the turning machine. The next step has been identified the cause of increase consumption of cutting tool and proposal for reduce of used cutting tool.

Security protection techniques of wireless networks of internet providers
Žiško, Róbert ; Pelka, Tomáš (referee) ; Burda, Karel (advisor)
This master’s thesis can be used as the guidebook for Wi-Fi networks provider in non-licensed zones 2,4GHz and 5GHz. It is good tool to understand wireless technology area and its protection. Reader can follow network design and avoid mistakes that are mentioned in work. This text shouldn’t be a tool or a guide for possible attackers, but an impulse for small providers who provide their networks in unsecured form. In the opening chapter of my work, matters of Wi-Fi networks are thoroughly analyzed. As they are able to get internet connection in a lot of inaccessible places, they are considered to be crucial for the present times. The basic procedure describing Wi-Fi planning is written in thesis and also its legislative that has to be strictly observed. The big disadvantage is riskiness of the wireless connection that allows attackers to attack network in many ways. For mentioned reason it is very important to take utmost account of Wi-Fi network’s security and attack resistance. Unfortunately a lot of networks are either secured partially or unsecured at all. These types of networks are frequently attacked in order to get “free” Internet access or because of competitors fight. In the text below we can find possible Wi-Fi attack forms using by attackers to get Internet access or destroy network hardware what can cause big financial loss to providers. I described design and realization of little-town network using safety tools implementation based on my experience. For that purpose I implemented benchmark tests in graphics as well as practical format.
