Methods of Authentication to WiFi Network
Valašek, Filip ; Kašpárek, Tomáš (referee) ; Lampa, Petr (advisor)
This diploma thesis deals with authentication using RADIUS protocol and authentication methods in accordance with standard IEEE 802.1X. At the beginning there are shortly characteristics of chosen authentication methods, such as CHAP, PAP and some EAP types. Document includes summary of RADIUS protocols implementations, especially the FreeRADIUS server. Our goal is to implement a management tool to adminitrate FreeRADIUS server.

802.1X Based Wireless Network Security Audit
Antal, Lukáš ; Samek, Jan (referee) ; Drozd, Michal (advisor)
This term project analyzes the security of 802.1X based wireless networks and presents the methodology for auditing these networks. The thesis describes various methods of the EAP authentication protocol used in wireless networks, security risks arising from their usage and recommendations for mitigating these risks. The paper also includes implementation of applications for 802.1X based wireless network audit focusing on the EAP protocol processing.

Security Analysis of WiFi Networks
Butela, Michal ; Malinka, Kamil (referee) ; Cvrček, Daniel (advisor)
This document provides overview of commonly used standards and mechanisms for securing the wireless network based on Wi-Fi protocol. It is covering all important security areas including confidentiality, integrity and authentication. We can find here also detailed analysis and description of functionality of listed mechanisms. Description of possible attacks against listed security mechanisms. There is a measurement of influence of encryption to transfer speed in the another section. It's followed by attacks against particular security mechanisms. And finally, description of deployment of central authentication system.

Analysis of security and authentication of wireless networks
Kulíř, Tomáš ; Jeřábek, Jan (referee) ; Szőcs, Juraj (advisor)
This master's thesis deals with wireless networks, mainly about the WiFi. It deals with summary of individual security mechanism both theoretically and using them in real hardware. Mainly it is interested in the security of the individual mechanisms and their weaknesses, which cause rupture of security. At each chapter the ideas and methods, that the attackers are trying for infiltration of wireless networks and decrypt encryption WEP, WPA or WPA2, are outlined. The principle of the authentication of the WiFi by the authentication server and its options, which is connected with directory service LDAP, is also explained in this thesis. The penultimate chapter deals with the summary of security mechanisms and references that should be adhered by design of the WiFi for the provision of the high security. The ending of the master's thesis is devoted to social engineering and its most famous representatives.

Wireless Network
Šumaj, Boris ; Janováč, Dušan (referee) ; Koch, Miloš (advisor)
The content of this thesis is to illuminate the basic issues of wireless networks. It gives an overview of IEEE 802.11 standards. I´ll analyze these standards with special emphasis on their security and architecture. The next step will be the subsequent creation of a secure corporate network according to the established facts of a particular company.

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.

Autentizace síťových portů pomocí protokolu 802.1X ve firemním prostředí
Malinka, Tomáš
This thesis describes the draft and implementation of a new security with 802.1x in the corporate environment. The work is divided into two parts. The first part outlines the topic theoretically and the second part solves specific draft using 802.1x and its implementation in the corporate environment. The implementation is outlined with configuration of end clients, switches including RADIUS server and settings in AD. During the implementation, there is also described the authentication of devices by Mac Authentication Bypass.

Language and content integration models in ELT
Synková, Blanka ; Gráf, Tomáš (advisor) ; Klégr, Aleš (referee)
The thesis focuses on the topic of language and content integration in ELT in a broad sense, i.e. it discusses not only CLIL but also other models of content-based teaching, viz. ESP (English for Specific Purposes), EAP (English for Academic Purposes), and EMI (English-medium Instruction). In the theoretical part of the thesis, these models are described as regards their history, typical features, teachers, learners, as well as benefits and negatives. The empirical part of the thesis explores the current practice of language and content integration at Czech general secondary schools ("grammar schools"). The research is based on case studies of five teachers who teach various courses belonging to this category. The preliminary research investigated what courses are currently being offered at grammar schools in Prague; they are mostly elective courses. Our research findings suggest that language and content integration in the form of elective courses is a rather common practice, although often unconscious. Teachers tend to act on the basis of their intuition rather than their knowledge of theory and practice of language and content integration. Generally, it seems that more emphasis is put on content than language in these lessons. Content-based English lessons may be beneficial for learners for...
