Extension of the Monitoring Probe with Wi-Fi Support
Findra, Michal ; Tisovčík, Peter (referee) ; Orsák, Michal (advisor)
The purpose of this work is to study Wi-Fi networks and their security and to create an extension for network probe, which is able to catch and analyze Wi-Fi traffic developed by The Accelerated Network Technologies (ANT) research group on FIT BUT. Study of software flexprobe components are described with proposal of wireless extension. Wi-Fi standards are described with their flaws and tools to crack Wi-Fi security with ability to intercept traffic on specific network. Implementation of wireless extension with testing is described in the last part of this thesis.

Internet of Things (IoT) Security Risks and Threat
Urbanovský, Jozef ; Grégr, Matěj (referee) ; Ryšavý, Ondřej (advisor)
The bachelor's thesis deals with the issue of security and attacks on the Internet of Things devices. The document addresses nature of Internet of Things, its characteristics and information security. The thesis analyzes dierent protocols and standards used by Internet of Things and types of network attacks. Part of work consists of packet capture analysis from IoT honeypot and showcases discoverd attacks. In fnal part, one specifc IoT device is analyzed in terms of security, around which is created an experimental IoT system. Subsequently this system is penetration tested with dierent attacks, thus creating new datasets.

Benchmarking Performance of WiFi Networks
Hrabčak, Miroslav ; Kašpárek, Tomáš (referee) ; Čejka, Rudolf (advisor)
This bachelor project discusses throughput problems of the WIFI networks. Project analyzes typical problems and factors, that affect decrease of their capacity and concentrates on typical problems of their signal path. Describes techniques of monitoring, detection and debugging causes, which affects decrease of network throughput. The project also includes the experimental testing and analyzes of standards 802.11b/g and 802.11n on the labs WiFi network.

Preventing attacks 802.11
Štefanec, Filip ; Kenyeres, Martin (referee) ; Novotný, Bohumil (advisor)
The main focus of this bachelor's thesis is on issues with security in wireless networks, based on standard 802.11. It includes description of most used encryption process and authentication methods in 802.11 networks. Also it explains functionality of EAP and RADIUS protocols, which are the main part of WPA/WPA2-Enterprise security mode. At the end of the thesis there is simulation of basic attacks on standard 802.11 and consequently desing and implementation of security, which prevents similar attacks. Implementation of security is based on authentication of clients through RADIUS server.
