Advanced network device scanner
Procházka, Michal ; Blažek, Petr (referee) ; Holasová, Eva (advisor)
The master thesis focuses on problem of identifying device types on a local network. The work explores current methods for device recognition on local networks and examines a survey of open-source tools capable of identifying these devices or gathering additional supplementary information. The discovered tools are compared based on several criteria. Furthermore, a laboratory environment is created for testing the identified tools as well as for testing own implementation. Subsequently, this thesis presents a proposal for the own implementation of a device identification method and the retrieval of advanced information about these devices. The main part of the work focuses on describing several possible methods of device identification, including practical examples. Scripting of the practical examples is implemented in Python or through the command line. Based on the outlined approaches, the thesis presents a list of all recognized devices from the experimental setup. Finally, the methods are compared in terms of network utilization during scanning.

Network probe module for energy protocols analysis
Nguyen, Minh Hien ; Burda, Karel (referee) ; Blažek, Petr (advisor)
Energy protocols are already increasingly entering our daily lives. With the development of smart grids, meters and appliances, more and more customers are demanding faster and more accurate consumption readings, as well as efficient information about the status of the energy network and control over energy use. The theoretical part of this master's thesis focuses primarily on the description of energy standards and protocols (IEC 60870, IEC 61850, DLMS and DNP3). Before the design of the analyzer, the network probe was first tested for load and stress. Once the criteria were met a DLMS energy protocol analysis module was created. The output is a set of statistics and values and can be used as a basis for machine learning and artificial intelligence. Furthermore, the thesis described the possible attacks on the energy protocol and proposes suitable detection methods based on the Suricata module.

Creating an industrial scenario using WinCC Unified
Šotola, Bohuslav ; Blažek, Petr (referee) ; Pospíšil, Ondřej (advisor)
This bachelor thesis is devoted to the Creation of industrial scenario by means of using WinCC Unified. WinCC Unified is a visualization tool supporting remote access via the web without the necessity to install softwares. The urgency for using this technology results in particular from the introduction of digitization and the associated simplification of industrial processes. The issue of remote communication is discussed at first which is followed by a description of the basic functions of WinCC Unified. Then various communication scenarios are processed which are the main target of the bachelor’s thesis together with the creation of the HMI library. The work is ended by the topic of analysis of communication load between HMI and PLC depending on the number of animated objects on the HMI screen.

Advanced generator of modern Slow DoS attacks
Trávník, Kryštof ; Blažek, Petr (referee) ; Sikora, Marek (advisor)
This thesis deals with the development of a modular generator for slow denial-of-service attacks. The theoretical part discusses in detail the evolution of the HTTP protocol, denial of service attacks, selected slow denial of service attacks and finally mentions some existing generators. It is possible to add any number of additional scripts to the created generator, to which a graphical interface is automatically created. The attacks can be further extended to a distributed version using the created bots, which are controlled thanks to the master-slave protocol proposed in this work. During the attack, statistics are generated and presented in real time within the graphical interface or after the attack is completed.

Parish history in Ústí nad Orlicí and the Roman Catholic Church in Czechoslovakia in years 1948-1961
Sklenář, Michal ; Pullmann, Michal (advisor) ; Blažek, Petr (referee)
The thesis follows the history of the Roman Catholic Church in Czechoslovakia between 1948-1961. The first part includes broader theoretical context and the second part contains historical context of the issues which are discussed in the third part. On the example of Václav Boštík, the dean in Ústí nad Orlicí between the years 1934-1942 and 1945-1961, and using the micro-historical method, the thesis demonstrates the running of a parish in a district town during the first thirteen years of the communist totalitarian rule. The options and actions of dean Václav Boštík - an ecclesiastic administrator and statutory representative - in various situations and his decisions, which had a direct and significant influence on the parish, are analyzed in the thesis. At the same time, the presented local situation is compared with the steps of the state towards the Church on the national level, which shows one of possible pictures of the ecclesiastical history in Czechoslovakia in the second half of the 20th century. Key words 20th century, the Roman Catholic Church, Czechoslowakia, communism, Ústí nad Orlicí, Václav Boštík (1897-1963)

Jozef Lenart and his political activity 1963-1970
Cvrček, Lukáš ; Rychlík, Jan (advisor) ; Blažek, Petr (referee)
Má diplomová práce především vzhledem k jejímu plánovanému rozsahu rezignuje na pokus být kompletní biografií Jozefa Lenárta, významného komunistického státního a stranického činitele, a omezuje se pouze na sledování jeho politické kariéry v letech 1963 - 1970. Celá práce je rozdělena na dva větší celky s odlišnou koncepcí líčení událostí. První část se zabývá obdobím vymezeném rozmezím let 1963 až 1967. Tuto velkou kapitolu jsem rozdělil na podkapitoly podle tematického hlediska. V nich se zabývám Lenártovým podílem na řízení strany a státu, a tím pádem i na nejdůležitějších politických událostech sledovaného období (rehabilitace, ekonomická reforma). Ve snaze přiblížit Lenárta alespoň útržkovitě jako člověka, jsem učinil také malou odbočku pojednávající o Lenártově životním stylu. Předěl mezi oběma celky tvoří kapitola o Novotn~ho nuceném odchodu z funkce prvního tajemníka. Pro vylíčení Lenártových činů a postojů v bouřlivém období let 1968 - 1970 jsem zvolil chronologicky navazující styl řazení událostí.

Legal and ethical aspects of the protection of the beginning and end of human life and its dignity
Blažek, Petr ; Gerloch, Aleš (advisor) ; Salač, Josef (referee) ; Doležal, Tomáš (referee)
The subject of the following dissertation, as the title states, is to explore legal and ethical aspects of the protection of human life and its dignity. Its aim is not merely to attempt to map the present legal situation regarding the protection of human life in the legal system of the Czech Republic, but also to outline some philosophical and anthropological implications which could have considerable influence on the practical consequences of some legal measures, including general aspects of the protection of human life and the legal regulation of two areas of study chosen by the author, namely assisted reproduction and euthanasia. In this sense the following work does not simply describe the various philosophical- anthropological conceptions in a neutral way, but offers to the reader a possible model which, in the view of the author, best corresponds to the degree of protection that human life and dignity can claim in early and terminal phases, taking a neoscholastic and personalistic view of man and his ontological status, in order to try to deduce from this model ethical implications both in a general sense and in relation to the two above-mentioned areas of application. The aim of the work is thus not only to describe the degree of protection of human life de lege lata, but also by making comparisons...
