Phishing and other risks of public Wi-Fi networks
Mäsiar, Daniel ; Luc, Ladislav (advisor) ; Sedláček, Jiří (referee)
This bachelor's thesis deals with problematics of public wireless networks, with focus on tho-se operating in densely populated areas such as public transport, libraries or fast-food restau-rants. The goal of this thesis is to evaluate how users of public Wi-Fi networks behave, what their customs are and how high is their awareness about possible threats. In the intro of the theoretical part of this paper, main standards and norms are listed, essential terms are defined and various types of possible wireless attacks are presented as well as briefly described. Further, this thesis inspects possible ways of protection against these attacks and finally, term phishing is concisely defined. The empirical part is dedicated to creating of a suitable tool for gathering statistical data about awareness of users at public places. Further, this tool is used in combination with phishing methodics for the actual statistical research. The whole process will follow the rules and laws defined by The Office for Personal Data in Czech Republic.

Internet of things and navigation applications
Kouba, Václav ; Luc, Ladislav (advisor) ; Veber, Jaromír (referee)
This bachelor thesis is focused on the internet of things and GPS navigation applications. The first part of the thesis consists of theoretical basics to familiarize the reader with the internet of things, its development, areas of use and security. Currently, built in navigation devices and navigation applications in smartphones are used separately, the internet of things is going to change that. In the second part todays GPS navigation applications are analyzed and compared based on the selected criteria and it is verified if the navigation applications for smartphones can replace the built in solution of BMW X5. The applications are compared based on their functions. The aim of this thesis is to analyze each of the selected applications and compare them based on the selected criteria and choose the best replacement for the built in solution until there are combined solutions available with synchronization between the built in navigation system and a navigation application.

Use of Raspberry Pi in the home
Müller, Jan ; Luc, Ladislav (advisor) ; Veber, Jaromír (referee)
This work is devoted to description of Raspberry Pi computers, their commissioning and verification of their functionality by the author. The first part deals with the basic introduction of Raspberry Pi single-board computers, the Raspberry Pi Foundation and a short history of computer development. Three competing products of the present time are also described. In the practical part, the author describes how to get the Raspberry Pi computer to work for common computer users using the Raspbian operating system and memory card and everything is validated by the author. In the last phase of the work, the use of Raspberry Pi is described for household monitoring and for monitoring of various variables. The author of this work verifies that by connecting a Raspberry Pi camera module or various sensors such as temperature sensor or motion detection sensor. There will be briefly described other possibilities of using Raspberry Pi computers at the end of the thesis.

Malware and comparison of antivirus products
Hamouzová, Aneta ; Luc, Ladislav (advisor) ; Novotný, Jakub (referee)
This bachelor thesis deals with the issue of possible danger in the Internet environment, namely malicious software. It is a variety of computer viruses, worms and Trojans that are comprehensively called malware. This risk should be closely monitored because its development is constantly moving forward and everyone should be familiar with this topic. The theoretical part includes the characteristics of malware - clarification of the concept and definition. The following part is history, which is described from initial ideas, the first malicious code in the 70's, and other well-known programs. It is led to the present day which is mainly focused on today's goals and direction of development of further malware. Next part involves the distribution of malware to basic, other special types and other such related forms. The final part describes the preventive and protective measures, and how to reveal and what to do if computer is infected. On this last section follows up a practical part, in which is analyzed antivirus protection, which is available in Czech and world market. Based on this analysis is done comparison of selected free antivirus programs. These are compared according to established criteria, such as web pages, installation, the use, user settings, appearance and ability to detect malware. The goal is to determine the safest and most comfortable user program. The result is used for ordinary users as possible support when they are choosing antivirus to their own computer.

Risk analysis of IoT from the perspective of modern office buildings
Hemžal, Adam ; Luc, Ladislav (advisor) ; Veber, Jaromír (referee)
This bachelor thesis deals with the issue of information security risk management amongst devices of the Internet of Things mainly in the modern office buildings of a company. The theoretical part of the thesis describes the terminology of risk management, information security management and describes the functioning, security and relation of the Internet of Things towards information security. The main component of risk management is their analysis. Therefore practical part discusses the risk analysis of selected devices of the Internet of Things, which are placed in the modern office building of the company. Before the analysis a sample company is defined and then an analysis of risk of these devices is made following the norm "ISO/IEC 27005 Information security risk management." The output of the thesis is a draft of measures that minimize a nascence or possible risk damage within selected devices of Internet of Things on a sample company.

eGovernment of the Visegrad Group countries
Francová, Eva ; Luc, Ladislav (advisor) ; Lechner, Tomáš (referee)
The objective of this Bachelor Thesis is evaluation of eGovernment evolution and its modernization using the new ICT technologies in countries of the Visegrad Group (V4). Gained information is compared with the average of~European Union. The theoretical part contains the definition of basic terms and characteristics of eGoverment. This Thesis describes individual eGovernment projects of~each country of the V4: Slovakia, Hungary, Poland and especially the Czech Republic. Following part of the Thesis focuses on contemporary strategies and issues of eGovernment. One of the main condition for the~evolution of eGovernment services is the usage of ICT and Internet by individuals in the~relation to the government and their digital literacy. The third part of the evaluation is broadband as a technological aspect. Very important part of further eGovernment evolution are Human Resources - post secondarily and tertiarily educated ICT professionals. The practical part of the Thesis analyses the current state of these indicators using free database of EUROSTAT. Gained data help to interpret the present state and predict how much would chosen countries be able to adapt to the market changes in the field of eGovernment services.

Methods for identification and preparation of incident solutions caused by malicious software
Bárta, Jan ; Veber, Jaromír (advisor) ; Luc, Ladislav (referee)
This bachelor thesis deals with the description of methods for identification and preparation of incident solutions caused by malicious software, which can be retrieved by its various forms. In the theoretical part, the reader is firstly introduced to the situation before the occurrence of a security incident. Along with this, there are presented currently the most widespread types of malicious software, ways of spreading, its forms and tools for communication with attackers. Then follows initial response to the incident, after that there is described the measurability of security incidents, categorization, classification according to various criteria and determination of safety classes. The practical part, which is dealing with incident solution procedures, analyzes the security incident and explains in details, how to behave in this situation and about what to be aware. For the sake of completeness, the future development of the informatics industry is also mentioned. The aim of this thesis is to create a complex that can be used for example as a supporting material for the incident solutions caused by malicious software, which primarily affects security.
