Configuration of Single Sign On against Active Directory in enterprise network
Křenek, Jan ; Pavlíček, Luboš (advisor) ; Bruckner, Tomáš (referee)
This work discusses about configuration and integration of Single Sign On against to Active Directory which serves as an authorization into web applications for Air Navigation Services, CZECH REPUBLIC by company Ifield Computer Consultancy Limited. Part of the work is performed the results of testing of the performance these two type of implementations for two different applications. For the theory part I've been using relevant literature, but for some tools, namely Scimark and JMeter, there is none, so I had to settle with internet sources. The main benefit of this thesis is the result of testing of comparison two different implementations of the Single Sign On generated using NTLMv2 and SPNEGO/Kerberos.

Indoor positioning systems, implementation and realization
Strnad, Pavel ; Bruckner, Tomáš (advisor) ; Pavlíček, Luboš (referee)
Bachelor thesis deals with the topic of localization inside buildings. The first part deals with the technologies and systems used for localization, while explaining the basic princi-ples and problems of implementation of these systems, their benefits and disadvantages. This section explains the functionality of each technology and the purpose for which it is best suited. The next part deals with the actual implementation of the localization system Redpin within the campus of the University of Economics in Prague. This section summarizes basic information about the project Redpin, then there is dismantled architecture of the system and its functionality. The remaining part is devoted to the direct implementation of this system.

The thesis is divided into three parts. Theoretical part deals with the introduction to the phishing issue and historical development of this fraudulent technology since the early 90s of the 20th century. Furthermore, the theoretical part describes the functionality of different types of phishing techniques from the most famous to the less well-known. The end of the theoretical part describes the prevention and defence possibilities at user, software and organizational level. The second part of the work focuses on the analysis of phishing attacks. First the thesis analyses some of the recent attacks on Czech clients, in particular their structure, progress and the real purpose. The following parts show the preparation and process of one classic and one modern attack with examples of detection and possibilities of appropriate defence against these specific techniques. Final part of the thesis shows the results of the survey and phishing quiz, focused on ordinary internet users and their awareness of this issue.

Usage of event processing systems for log analysis
Bašta, Vojtěch ; Pavlíček, Luboš (advisor) ; Stanovská, Iva (referee)
This thesis is focused on complex event processing technology, available software solutions for log processing and also on application of Esper library in an example where HTTP logs of an information system are analyzed. Work is divided to five chapters. The first one presents a complex event processing technology. The second chapter analyzes the available software solutions for processing logs. One of which - Esper CEP technology - is selected as a representative. The third part of the thesis is devoted to analytical library Esper. In the fourth chapter the entire solution with all the components and interactions between them is described. In the last chapter I present the EPL language options for defining queries over events. The solution also includes the definition of rules for detection of undesirable behavior. The entire solution was tested against historical data for the past two years.

Server and application virtualization via Docker
Tomášek, Patrik ; Pavlíček, Luboš (advisor) ; Bruckner, Tomáš (referee)
This bachelor thesis covers virtualization at level of operation system using a new solution called Docker. The aim is to introduce the topic and to describe how to create Docker container. The key to achieve those objectives lies in identifying and studying available relevant materials and processing the information gained from the study in order to create an application container. As an introduction to the topic of Docker, the theses briefly mentions the history of virtualization and currently used sorts of virtualization. It describes Docker and necessary knowledge for basic understanding of the issue and further practical sections of thesis. The main part of this thesis sheds light on installation and configuration of Docker, download and launch of already existing Docker container. Furthermore it documents how the author designs and creates his own application container with preselected app.

Phishing and the human factor
Kalinová, Diana ; Sigmund, Tomáš (advisor) ; Pavlíček, Luboš (referee)
The main aim of the diploma thesis is to underline the importance of human factor for the success of phishing attacks and to identify the reasons, why the Czech and Slovak users are vulnerable to phishing. The thesis focuses on the user as the weakest part in the system which phishers exploit. Social and technical tricks that are cheating users are in the second chapter. The third chapter focuses on social engineering and sociological methods of attack. The fourth chapter is devoted to the delivery of phishing and fifth chapter explores the various types of phishing attacks. The sixth chapter presents the reasons for the operation of phishing, the aspects of credibility and authenticity of e-mails and web sites, that users follow and the implications of using the context in phishing. The victims of phishing have specific reactions which are mentioned in the seventh chapter. The eighth chapter explores the various measures against phishing, not just technology. Mentioned eight chapters present a theoretical basis for the following chapters of the diploma thesis. In the ninth chapter is performed analysis of the global situation of phishing. Through analysis are identified current and historical trends in phishing. Finally, the chapter shows the implications for the user. The tenth chapter is devoted to the phishing attacks in the Czech and Slovak Republic which are interesting in terms of the importance of human factor. We determine whether users are able to defend attacks only with their carefulness, mindfulness and awareness of phishing. Within the last chapter is taken empirical research through the questionnaire survey.
