Utilization of open source tools for access network monitoring
Gmitter, Jakub ; Sládok, Ondřej (referee) ; Grenar, David (advisor)
The bachelor thesis deals with the issue of access network monitoring, which is necessary to ensure the stability of access networks. It contains a comparison of suitable monitoring tools for their selection. The work is focused on creating scripts in the Bash language, which analyze data on the access network and implement outputs from selected monitoring tools. In this work were analyzed the transmitted packets and the achieved transmission speeds during monitoring. The final output of this work are databases created in MySQL, which contains data about the analyzed parameters and visualization of data analysis using the Grafana program. Graphs of the transmission speeds of monitoring and basic transmission statistics were created on panels during visualization.

Analysis of possible threats in old OS Linux version
Chovancová, Emília ; Dejdar, Petr (referee) ; Tomašov, Adrián (advisor)
The bachelor thesis is focused on the security aspect of an older version of a Linux based machine. The document is split into a theoretical part which contains a description of what operating system, kernel, UNIX, GNU/LINUX and Linux OS are in general. Then the description proceeds to explanation of active and passive attacks such as replay, masquarade, denial of service, man in the middle or listening and analysing the network. Afterwards it continues with description of potentially vulnerable spots that are common on operating systems. With the help provided from scanning software, especially Nmap and Lynis, the document proceeds to the practical part which contains various types of successful and unsuccesfful attacks such as password recovery, denial of service, spectre, brute force of a password and cross-site scripting. The last part covers the protection against succesfull attacks and adds a little bit more of additional protection in general in a form of an ansible script.

SlowDrop attack detection
Náčin, Peter ; Blažek, Petr (referee) ; Sikora, Marek (advisor)
The diploma thesis is focused on the detection of a slow DoS attack named SlowDrop. The attack tries to imitate a legitimate person with a slow internet connection and does not show a new strong signature, so the attack is difficult to detect. The diploma thesis is based on the work of Ing. Mazanek in which the SlowDrop attack script was created. At the theoretical level, the issue of DoS attacks is described in general, but also in particular. Furthermore, the work develops methods for solving the problem of SlowDrop attack detection. The methods are then defined in detail and tested in a simulation environment. The practical part describes data analysis, signature detection, anomaly detection using neural networks and a detection script. In all practical parts, the used technologies and solution procedures are described in detail. The specific implementation of the solution and the achieved results are also presented. Finally, the individual results are evaluated, compared individually, but also among themselves. The obtained results show that the attack is detectable using a neural network and by created detection script.

Monitoring of services within active network elements by Mikrotik
Kamenář, Filip ; Slavíček, Karel (referee) ; Grenar, David (advisor)
This bachelor thesis deals with the monitoring of the VPN services on the networking elements Mikrotik. The theoretical part includes the description of RouterOS system, management options and networking devices used. The thesis consists of the description of the VPN services and analysis of PPTP, SSTP, L2TP and OpenVPN protocols, which are implemented in the practical part of this work. The theory also contains the description of monitoring devices included in the RouterOS system. In comparison, external tools are enlisted. Chosen monitoring tools are therefore implemented in the practical part of the thesis and in the monitoring script. The practical part of the bachelor thesis is focused on the establishment of VPN tunnels and its parameter measurement. The VPN clients are to be found in the Czech Republic, Ukraine and Egypt, which establishes the real conditions for network monitoring status. The final part of the work deals with the script, which is created for the automatic-monitoring of VPN service in the accessible network and sends the gathered data to the operators. The aim of the thesis is to illustrate the usage of integrated monitoring tools in the RouterOS system in the network built on the Mikrotik elements. The chosen monitoring service was the service VPN, which is being used for remote access to the local networks from distant part of the world by the corporations but also individuals. Individual monitored parameters are enlisted and compared depending on client geographic location.

Contemporary Czech TV series: methods used in screenplay development
Knéblová, Michaela ; Moravec, Václav (advisor) ; Štoll, Martin (referee)
The thesis deals with contemporary Czech serial production in terms of script development. It focuses primarily on the development of screenplays for the series on Česká televize and on drama series with one-hour episodes. It compares the development in the Czech environment with British and American practice. It maps the current Czech serial environment, creates an overview of contemporary Czech serials in broadcasting and clarifies the basics of narrative serial structure. It contains a comparison of selected pilot parts in terms of their narrative structure. It focuses on both screenwriting practice and development practices from the point of view of the television of public service, in the case of the American production it focuses on the Hollywood system. It uses methods of qualitative analysis of scripts, in-depth semi-structured interviews with creative producers and comparison of script development in individual productions.

Opera dei pupi
Jarošková, Karolína ; Flemrová, Alice (advisor) ; Sieglová, Tereza (referee)
The aim of this thesis is to introduce the popular puppet theatre called Opera dei Pupi, which was developed mainly in Sicily in the second half of the 19th century. The first part desrcibes literary influences that nourished this tradition, from which puppeteers derived topics for their repertoire. These stories were primarily about the French king Charlemagne and his knights and were called paladins. I am trying to map the form of an adaptation of this topic for Opera dei Pupi needs and the way of connection with oral tradition. Furthermore I am going to mention the secondary repertoire of the theatre for example farce. Next chapter focuses on a formal side of the Opera dei Pupi including puppeteer's personality, his work and activities, structure of the theatre itself, characteristics of puppets and handling them. Furthermore this section also describes a specific concept of everyday's performances "to be continued" and how were these performaces organized in practice. The analytical part focuses on a process of putting plot on a scene, which includes both improvisation and fixed rules approach. The principal theme of this part is the so-called copione, which are the puppeteer's own handwritten notes, on which the show was based. This section also includes numerous excerpts not only from copione but also...

Title: Structure of stage games Objectives: The main goal of this thesis is to work out directions about how to put together a stage game. To create a certain directions which would help others, be they organisers and instructors of camps or residential trips, with a preparation of a successful programme and to advise them on which mistakes they should avoid. Methods: The thesis is of a survey study character and it is based on research of available materials. The goal is to collect information and subsequently organise and interpret them in relation to the given topic. The thesis is not of the experimental type, it is rather a descriptive work and its structure is not connected to hypotheses and neither is it asking any scientific questions. Results: The results of this thesis are presented in the form of generally applicable recommendations in relation to the issues dealt with that is the stage games. That became the base of the proposal of a factual stage game called "The rescue of the planet" which was put into practice in April 2015. On account of sufficient literature directions for formation of a stage game was compiled. Keywords: stage, preparation, summer camp, script, organising
