Basic properties of network protocols and communication techniques
Cigánek, Josef ; Jeřábek, Jan (referee) ; Dvořák, Jan (advisor)
The diploma thesis is focused on the basic properties of network protocols. The main task is to create laboratory tasks that deal with the basic features of network protocols and communication techniques, along with detailed instructions for students of communication technologies. The theoretical part of thesis acquaints the reader with the topic of computer networks and the basic network protocols of the TCP/IP architecture, which occur within the created lab. The practical part contains a selection of testing environment and subsequent description of installation and preparation of selected GNS3 environment. Finally are presented labs, which have been created. First lab deals with the basic differences between TCP and UDP. The second lab is focused on the issue of multicast and the third deals with the basics of penetration testing.

Firewall Security Analysis
Cigánek, Josef ; Burda, Karel (referee) ; Hajný, Jan (advisor)
The bachelor essay is about security analysis and stress testing of firewalls. The main goal is to create a testing environment for eavesdropping of all communication of the firewall, on the principal of security analysis of the hardware firewall and stress testing with device Spirent Avalanche. The theoretical part of the essay is informing the readers about the problems surrounding firewall, security audits and penetration tests. The following practical part consists of commenting on the results of chosen security analysis and stress testing, applied in a laboratory for the hardware firewalls Hillstone SG-6000-G2120 and SG-6000-M7260.
