User Authentication and Autorization for New Generation Networks
Přibyl, Radek ; Cvrček, Daniel (referee) ; Matoušek, Petr (advisor)
This document describes methods of user authentication and authorisation via a trusted server. There is analysis of the system Kerberos, which is used as an inspiration for desing of a new authentication scheme. There are analysed programming layers and interfaces for specific applications ensuring user authentication and authorisation. The document contains a design and detailed description of a new authentication scheme. This scheme is implemented into the communication between email client and imap server.

Proposal of the secure network model
Kis, Matej ; Rosenberg, Martin (referee) ; Babnič, Patrik (advisor)
The goal of this work was to create a design of a secured network infrastructure with decribing different ways of securing at ISO/OSI layers. Create a list of protocols which can be used to achieve a secured network design. In the theoretical part of this work the attention was placed to analyze possible solutions, which can be appllied in a practical part of the work. The practical part involves a design of a network topology and simulation. The part of the simulation was device configuration and network security testing.

Implementation of advanced filters based on packet classification using Linux
Malár, Lukáš ; Holešinský, Pavel (referee) ; Matocha, Tomáš (advisor)
The Master’s thesis ”The Implementation of the Advanced Filtering Based on the Packets’ Classification using Linux” is intended to the realization of an internet gateway. The gateway serves to make the connection between local network and the internet. The thesis contains a short theoretic description of parameters and types of QoS services. The classful and classless queues are mentioned in detail. The last theoretic part refers to the introducing of LDAP protocol and its usage. The practical part of this thesis captures the configuration of firewall, dns and radius server connected with LDAP databases. The thesis also contains detailed description of the production QoS by HTB with L7-filter including the compilation of system’s core. The end of the thesis contains the series of tests of created scripts.
