Measurement of PlanetLab experimental network
Andrašov, Ivan ; Bečková, Zuzana (referee) ; Komosný, Dan (advisor)
This thesis deals with measurement of transfer parameters for nodes in experimental network PlanetLab. In theoretical part of this thesis we analyse experimental network PlanetLab, basic terminology in this network, its goals and some current projects run- ning under this network. Next we analyse measured network parameters specifically Ping, SSH delay and respond to SCP. Practical part of this thesis is formed around real im- plementation of measurement where in specific sub chapters are written exact problems of said parameter together with source code.

Al-Qaeda Before and After 09.11.2001
Andraščíková, Diana ; Makariusová, Radana (advisor) ; Ditrych, Ondřej (referee)
The objective of the master thesis is to evaluate the factors that have influenced the operational capability of al-Qaeda. In order to determine current operational capacity of al-Qaeda, the analysis is divided into three time periods and on the basis of external and internal factors affecting the changes in the structure and thus the functioning of the group, then the network, we have achieved results that we can consider as a basis for assessment of its ability to act today. Analysis of the structure of the al-Qaeda by network analysis based on the theory derived from the article of Ronald Diebert and Janice Stein entitled "Hacking Networks of Terror" is in the thesis considered to be a basis for understanding of the functioning of the network structure as well as its impact on the internal functioning of the network compared with hierarchically organized structure characteristic for the period before the terrorist attacks of 11 September 2001. The other two periods analyzed in the work are: the period after the invasions of Afghanistan and Iraq, their impacts and the third period is the period after 2011, when bin Laden, leader of al-Qaeda was killed, the revolutions of Arab Spring took place and the long-term impact of the war on terror will be included in the analysis as well. Analysis of...

Laboratory task demonstrates Intrusion Protection System
Bronda, Samuel ; Malina, Lukáš (referee) ; Martinásek, Zdeněk (advisor)
This bachelor thesis is divided into two parts. The theoretical part describes security systems, various types of attacks and details of systems to protect computer networks. The practical part focuses on the workplace, where will operate IDS / IPS system Snort and Suricata, the necessary adjustments and simulation of attacks. The bachelor thesis also includes putting the system into real terms.

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.

Network Configuration Synthesis and Verification
Černeková, Alžbeta ; Veselý, Vladimír (referee) ; Ryšavý, Ondřej (advisor)
The subject of this master's thesis is to address the topic of network devices configuring. It resolves the problems related to simplifying certain parts of configuration while eliminating frequent errors or issues. It introduces a solution to setting of IP addresses on router's interfaces. Furthermore it presents the generation of configuration for particular dynamic routing scenarios and its application and methods for its verification on network devices. It also demonstrates the preparation of configuration of VPN tunnel between two devices. The conclusion of this thesis contains possibilities for further extensions or improvements.

Connection of elektrothermal devices to the network
Sumka, Martin ; Lázničková, Ilona (advisor)
This thesis devotes with electrothermal devices and their behavior when connected to the network. It describes the basic types of electrothermal equipment, their structure, construction, principle of converting electrical energy into heat energy and goings that occur during their operation. It also examines the basic types and ways of dealing with compensation and symmetrization applied on different types of electrothermal equipment. It explains the basic methodology used for design of compensation and symmetrization of particular electrothermal equipment and components.

CACHE Memory Design for Network Applications
Soľanka, Lukáš ; Martínek, Tomáš (referee) ; Kořenek, Jan (advisor)
This thesis deals with design and implementation of generic cache memory for a wide range of network applications. Firstly, aspects with influence on performance are discussed. Then architecture is proposed and implemented with respect to the given technology. The main selectable parameters of the design are: data path width, line size, associativity, number of lines and replacement policy. Cache is also pipelined and therefore is able to process one request for reading or writing every clock cycle. The resulting component has been thoroughly simulated to verify its functionality and finally, its operation has also been tested in hardware on the Combo6X board.

Software design for mapping of the network topology
Janura, Dominik ; Novotný, Bohumil (referee) ; Sobek, Jiří (advisor)
This thesis addresses the issues of network topology mapping, where the network consists of multiple Cisco devices. It includes theoretical knowledge in this field and closely describes possible solutions to this problem. It explains the process of design and implementation of this kind of network mapping software by chosen means. Correct function of the created application is tested on a virtual network.
