Slow DoS attacks generator
Krivulčík, Andrej ; Zeman, Václav (referee) ; Sikora, Marek (advisor)
The work is focused on Slow DoS attacks and generating them. There are compared 3 most popular web servers and their defensive modules against this type of attacks. Closed are described network model TCP/IP, protocol HTTP (Hypertext Transfer Protocol), each DoS attack, Slow GET, Slow POST or Slow Read and also flood attacks. Afterwards the attack generator is described, with its functionality.
Electronic banking security
Tomko, Tomáš ; Sikora, Marek (referee) ; Zeman, Václav (advisor)
The main goal of this bachelor thesis Security of electronic banking is to characterize payment electronic services and possibilities of their realization and also comparison of offers of bank payment services in order to point out and draw attention to their security and risks involved. This thesis at first deals with the explanation of the basic concepts related to the issue, then the current available legislation of this sector is written, especially in the Czech Republic. It also deals with individual forms of electronic banking and their detailed description. One whole chapter is devoted also to one of the latest technology, the NFC. In the last chapter of the theoretical part is summarized electronic payment system. The practical part describes what is the output of this bachelor thesis.
Stress tester
Shpak, Kyrylo ; Člupek, Vlastimil (referee) ; Zeman, Václav (advisor)
The bachelor thesis deals with the issue of stress testing. The aim of this work is to extend the JMeter tool with amplification modules of DoS attacks. The beginning of the work introduces the issue of DoS attacks, along with a description of selected attacks. One of the points of the work is to verify the functionality and find errors of the stress tester, which is a comprehensive system for testing the information and communication infrastructure based on the JMeter tool. The last chapter deals with the implementation of DoS attacks.
Electronic signature in public administration
Ivanchanka, Darya ; Sikora, Marek (referee) ; Zeman, Václav (advisor)
The theme of the bachelor thesis includes the issue of electronic signature and its definition at the theoretical level and subsequently in terms of comparison for selected countries, which are listed in the practical part of the bachelor thesis. The theoretical part deals with the main concepts and problems such as the concept, function and technology of electronic signature, as well as the issue of e-government and public administration, which is also important for the solution of the selected theme. The practical part of the bachelor thesis includes a comparison of electronic signature in selected countries, such as Russia, Belarus and selected Baltic States. In the practical part is also elaborated the view of European law on the issue of electronic signature, its requirements and functions that the electronic signature should fulfill in EU countries. The educational application developed within the bachelor’s thesis is described in the practical part as well. This application will enable students to understand working of electronic signatures and its use in public administration.
Blue Pyramid Building Society, Inc. Financing for the Construction of a Hous
Loučková, Pavla ; Chytilová, Vladimíra (referee) ; Zeman, Václav (advisor)
The object of main master´s thesis called Blue Pyramid Building Society, Inc. – Financing for the Construction of a House occupies by the credits provided from Blue Pyramid Building Society, Inc. The goal of this study is proposing of a Handbook that should help to financial consultants of Blue Pyramid Building Society, Inc. by the process of a loan for financing for the construction of a house (including acquisition of a lot). In the theoretical part I aim at the general principals of the functioning of the building savings and building savings loans. In the practical part I aim at the process of a loan provided from Blue Pyramid Building Society, Inc. There is processed a proposal of the Handwork. In the final part the Handwork is applied to the specific case from practice to assessment of its operation.
Evaluation of entropy sources in common computers
Bafrnec, Matúš ; Zeman, Václav (referee) ; Burda, Karel (advisor)
This thesis is focused on entropy sources and their evaluation. It includes a brief introduction to the information theory, description of entropy sources, their parameters and characteristics and methods of evaluation based on the NIST organisation standard SP 800-90B. The following part of the thesis is dedicated to the description of two created programs and evaluation and comparison of entropy sources. Additionally, the last part describes the usage of hash functions in association with entropy sources.
Network tester
Štainer, Martin ; Člupek, Vlastimil (referee) ; Zeman, Václav (advisor)
The objective of this thesis is the issue of network parameters measuring. Measurement methodology and tester concept were designed. Based on the designed tester concept a plugin for Apache JMeter was implemented. Two experimental tests were run based on the methodology designed, with their objectives set to explore the difference in performance between QUIC and TCP protocols.
Blockchain technology and its use
Hrbotický, Lukáš ; Sikora, Marek (referee) ; Zeman, Václav (advisor)
This diploma theses concerns the matter of blockchain technology and its practical use, especially for nonfinancial services. Theoretical part describes the blockchain technology from the technological and juridical point of view and examples of its practical use are also mentioned. In the practical part two laboratory exercises were designed for further familiarization of the blockchain technology, in which students try some real applications on their own.
Software for entropy resource evaluation
Šelinga, Martin ; Zeman, Václav (referee) ; Burda, Karel (advisor)
This thesis is focused on exploring the sources of entropy. It includes a description of random number generators and tests used to evaluate entropy quality. Random number generator for Windows and Linux OS was created together with software for entropy evaluation. Subsequently, measurement of entropy was performed on physical workstations and Cloud environments.
Security Aspects of Applications in Angular 5 Platform
Čermáková, Martina ; Zeman, Václav (referee) ; Burda, Karel (advisor)
The bachelor thesis is focused on security aspects of Single Page Application in An- gular 5. The main goal is to introduce security risks for developing a web applications and afterwards to implement author’s own knowledge that should guarantee security of the developed application. In theoretical part the reader is introduced to OWASP Top Ten project and security risks in backend, where is primary put stress on XSS and CSRF attacks. In practical part there is created a web application in Angular 5, there are simulations of XSS and CSRF attacks including explanation and fix of security issue. The thesis also aims at security of REST service and includes a summarizing list of recommendations for developers to know how to create secure web applications.
