Web server attack analyzer
Mižišin, Michal ; Novotný, Miroslav (advisor) ; Mareš, Martin (referee)
In this work I will focus on the most common forms of attacks on web applications. My focus will point on so called Injection flaws (attacks where data given by user are interpreted and executed), XSS (Cross Site Scripting) and CSRF (Cross Site Request Forgery), that have for web application in case of compromisation fatal consequences. I will describe these attacks, their history, concrete examples of successful execution. I will propose also possible kinds of protection and possibilities of detection.

Trust Management Systems in P2P Networks
Novotný, Miroslav
of dissertation thesis Title: Trust management systems in P2P networks Author: Miroslav Novotný Department / Institute: Faculty of Mathematics and Physics Supervisor of the doctoral thesis: RNDr. Filip Zavoral Ph.D. The architecture of certain class of services, such as distributed computing, distributed storages or content delivering networks shifts from the traditional client- server model to more scalable and robust peer to peer networks. Providing proper protection to such complex, open and anonymous systems is very complicated. Malicious peers can cooperate and develop sophisticated strategies to bypass existing security mechanisms. Recently, many trust management systems for P2P networks have been proposed. However, their effectiveness is usually tested only against simple malicious strategies. Moreover, a complex comparison of resistance of a particular method is missing. In this thesis, we (1) propose a new trust management system called BubbleTrust and (2) develop a simulation framework for testing trust management systems against various malicious strategies. Our simulation framework defines several criteria which determine the success of each malicious strategy in the network with a given system. We present results of four trust management systems that represent main contemporary...

Novotný, Miroslav ; Tóth, Michal (referee) ; Milet, Tomáš (advisor)
The goal of this thesis is to learn about virtual reality and the aspects of the development for this platform. The next goal is to find well suited development environment for the application and test the capabilities and limits of them both. The thesis will be completed by designing, implementing and then testing the aplication using knowledge learnt.

Recatholisation Practice in Local Perspective.
Zahradník, Pavel ; Čechura, Jaroslav (advisor) ; Mikulec, Jiří (referee) ; Novotný, Miroslav (referee)
of the doctoral thesis Title: Recatholisation Practice in Local Perspective Subtitle: The Relationship of Re-Catholisation and Restoration of Ecclesiastical Administration in the Mladá Boleslav District and in the Northern part of the Hradec Králové District (selected questions). Keyword: recatholisation, ecclesiastical administration, baroque devoutness, District of Mladá Boleslav, District of Hradec Králové, 17th century, 18th century In this doctoral thesis I examine the relationship between lower ecclesiastic administration, re-Catholisation practices and advancing penetration of Baroque religiousness into the lives of inhabitants of the Mladá Boleslav district and of the Northern part of the Hradec Králové District in the 17th and 18th century. The activity ratio of mentioned agents is being observed on the basis of several selected questions. First, I define and explain key terms such as Catholic confessionalisation, recatholisation, Counter-Reformation, Catholic reformation and Baroque religiousness. Then I follow the proceeding of re-Catholisation of the Czech lands in the Central European context. The following chapter deals with the re-Catholisation legislation. Next part of my thesis describes gradual improvement in the operation of parish administration from the perspective of...

Education to Spirituality
Novotný, Miroslav ; Syřiště, Ivo (referee) ; Prokop, Jiří (referee)
The aim of this work is to create a pedagogical concept of the education for spirituality. I try to map the various views of human spirituality. The spirituality is one of the important philosophy topics, so I dedicated this view most. Next is the psychology, within witch I strive to grab this term in a scientific way. I also notice the changes in the perception of the term spirituality, namely in the relation to the religion, as well as to the usage of this term, which is equivalent to the previously frequently used term inwardness. Marginally I also mention some theories related to the spirituality in the field of biology, quantum physics and brain research. After the initiation of some way outs, from which can be created the conceptual apparatus, I come to my own definition of the spirituality, I concretize the education to the spirituality including the initiation of goals, methods and means of this education. The part of this work is also a small study, in which I try to find out, what is the degree of the respondents spirituality, what forms and methods do the respondents evolve their spirituality and I am looking for the contexts between the respondents characteristics by practicing the various technics and the spirituality rate. Research questionnaire method is conceived quite broadly, to...

Web server attack analyzer
Mižišin, Michal ; Novotný, Miroslav (advisor) ; Čermák, Miroslav (referee)
Web server attack analyzer - Abstract The goal of this work was to create prototype of analyzer of injection flaws attacks on web server. Proposed solution combines capabilities of web application firewall and web server log analyzer. Analysis is based on configurable signatures defined by regular expressions. This paper begins with summary of web attacks, followed by detection techniques analysis on web servers, description and justification of selected implementation. In the end are characterized possibilities of further development in area of better results of false positives. Implemented detection of all proposed attacks did slow down server response time by 10% and was able to detect more than 99% SQL injection, Path traversal and SSI injection attacks contained in web application security scanners.
