Simulation scenarios in NS2 demonstrating knowledge obtained in the MPKT course
Mašek, Jan ; Mlýnek, Petr (referee) ; Jeřábek, Jan (advisor)
The aim of the bachelor´s thesis is to develop simulation tasks for modeling of data networks. The tasks will be used in the course Modern communication technique (MKPT). The networks are simulated in the environment of Network Simulator 2 (NS2). A brief description of program environment NS2, as well as basics of Tcl language is mentioned in the introduction. Described is the possibility of simulation HTTP protocol in NS2 using OTcl PagePool classes. Totally six proposed tasks form the core of the thesis. The first task uses PagePool/Math and displays the simplest communication between client, server and cache. Next task uses PagePool/CompMath and it shows the communication between client, cache, Web server, FTP server and FTP client. The task, that uses PagePool/WebTraf class, simulates communication between two clients and three servers. The last three tasks are of different topologies and course of communication using PagePool/ProxyTrace. The exercises of this class are the most complicated and their input files allow defining whole communication. The outputs of exercises are given in graphs, log files of HTTP communication and the last task contains detailed instructions.

Tool for Analysis of JavaScript to Detect DOM XSS Vulnerabilities in Web Applications
Barnová, Diana ; Polčák, Libor (referee) ; Homoliak, Ivan (advisor)
The main goal of this thesis is to design a tool for analisys of JavaScript to detect DOM--based XSS vulnerability in web applications. Then to implement it and test it ethically. Cross--side Scripting (XSS) is one of the most common injection attacks on web applications that insert malicious code in an otherwise trusted site. An interpreted response by the browser is required for the detection and subsequent exploitation of DOM--based XSS vulnerabilities, therefore the tool captures the response from the Burp Suite proxy server. The analysis of this response uses two separate regular expressions aimed at searching for sources and sinks in the source code of the response. A set of payloads is used to determine if a site is exploitable. Subsequently, the user is warned of the possible danger. The output is a text file summarizing the results for the URL.

System for Automatic Object Tracking
Kerndl, Michal ; Macháň, Ladislav (referee) ; Šteffan, Pavel (advisor)
There is suggestion of obtaining exact position in this work, based on GPS and GSM modules controlled by PIC microcontroller. Layout of this work is electronic schematic, PCB footprint and theoretical analysis of used modules. The practical part of work is also dealing with software for both microprocessor and web interface. The function prototype will be created and tested in next phases of this project.

Identification of Useful Data for Lawful Interception
Holomek, Tomáš ; Veselý, Vladimír (referee) ; Polčák, Libor (advisor)
This thesis deals with the identification of useful data in lawful interception. First part summarizes the standards related to computer networks and lawful intercepts. Next part of the project focuses mainly on the HTTP application protocol, which is described in version 1.1. The work also specifies the classes into which the data traffic can be divided according to the importance to law enforcement agency. It introduces several methods of distribution of data streams into the proposed classes. Finally, the implementation of this methods has been tested for usability in network lines used today.

Centralised web-based personal data management system
Mazur, Kornel ; Kacálek, Jan (referee) ; Malý, Jan (advisor)
This diploma thesis deals with a central user identification and personal data management on the Internet. The first part analyzes questions of a identification process and discusses the requirements for implementation, security and user-friendliness. Subsequently, the process is designed with respect to the defined requirements. A detailed overview of possible attacks to the system and means of protection against them is also included in the thesis. The described methods are as follows: Phishing, Man in the middle, hardware modification and acoustic keypress emissions. A practical design of a identification system is discussed in the second part of the thesis. It consists of two parts: a library implementable to individual Internet services requiring a user identification and a server centrally identificating the users and storing their personal data and passwords. An implementation in Joomla content management system is also described.

Automation of MitM Attack on WiFi Networks
Vondráček, Martin ; Lichtner, Ondrej (referee) ; Pluskal, Jan (advisor)
Tato bakalářská práce se zaměřuje na výzkum v oblasti bezpečnosti bezdrátových sítí. Práce přináší studii široce využívaných síťových technologií a principů zajištění bezpečnosti bezdrátových sítí. Analyzované technologie a způsoby zabezpečení trpí slabinami, které mohou být zneužity k provedení útoku MitM . Práce zahrnuje přehled dostupných nástrojů zaměřených na využití jednotlivých slabin. Výsledkem této práce je balíček wifimitm a CLI nástroj, oba implementované v jazyce Python. Balíček poskytuje funkcionalitu pro automatizovaný útok MitM a může být použit jako součást dalšího software. Nástroj wifimitmcli je schopen úspěšného provedení plně automatizovaného útoku bez jakéhokoli zásahu útočící osoby. Tento výzkum nachází využití v oblasti automatizovaných penetračních testů a forenzního vyšetřování.
