Secure Network Based on Virtual Next-Generation Firewall
Varmus, Pavol ; Burda, Karel (referee) ; Malina, Lukáš (advisor)
The bachelors thesis aims to study the issue of security of the networks that use firewalls. The next goal is to evaluate the characteristics of a different types of firewalls and to summarize its results. The other object is to design a small or medium sized network with description of best practice. The main objective of the thesis is to design a lecture task for students to test with a step-by-step solution. This task is for students to undertand the importance of firewalls as a network protection service tools and to try out different types of filters for maintainin network security. The task ends with a practical stress test made by a network attack in order to see its resistance to the attack.

Analysis of vehicular ad hoc network
Varmus, Pavol ; Mašek, Pavel (referee) ; Kubánková, Anna (advisor)
This diploma thesis aims to study VANET (vehicular ad hoc network), to describe the theory of this networks and describe attributes of these networks and to set the starting point for practical part. Thesis includes VANETs possibilities, its signal transportation and description of routing protocols. Another goal was to familiarize program NS-3 and set up simulation models in its interface. The main output of the practical part is program which simulates vehicle movement in Brno city and set the communication module which is adapted to fulfill the most realistic transmission capabilities. Practical part is divided to two parts. The goal of the first one was to simulate basic communication in theorized unrealistic scenario and the second part was the more realistic scenario. Overall, throughout the practical part was tested a variety of attributes, such as mobility models, standards, routing protocols and other parameters that provided diversity in final results. All the results, which consisted of summary of basic transmission capabilities and reclassification of the applicability of those technologies in real world, are discussed in the summary of the simulations output.
