System Log Analysis
Ščotka, Jan ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
The goal of this master thesis is to make possible to perform system log analysis in more general way than well-known host-based instrusion detection systems (HIDS). The way how to achieve this goal is via proposed user-friendly regular expressions. This thesis deals with making regular expressions possible to use in the field of log analysis, and mainly by users unfamiliar with formal aspects of computer science.

A Tool for Post-Mortem Debugging
Kapičák, Peter ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
The goal of this work is checking specific properties in trace which program should meet or which it shouldn't meet. Properties and their description are basis of this tool for post-mortem debbuging. Properties are transformed to deterministic finite automaton for checking in trace and their description is important for searching events in trace. Events are pass to automaton as input. Output of a tool is report if properties are meet or not. Solution provides check of properties regardless of log format and shows events that preceded violation of the properties.

Detection of attacks targeted at web applications
Jégrová, Eliška ; Gerlich, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
This thesis is dealing with vulnerabilities of web applications. The aim of the work is to create tools for attack detection of certain attacks, specifically Same Origin Method Execution (SOME), XML Signature Wrapping attack, XPATH Injection, HTTP Response Smuggling and Server-Side Includes (SSI) injection. Another aim is to create logs that display detected attacks. In the first part, the theory is analyzed and vulnerabilities of chosen attacks are described including their misuse. In the next section there are web application implemented which contain vulnerabilities for successful execution of the attacks. Furthermore, in Python language detection methods are designed and developed for these attacks, which are accompanied by a log entry.

Information System Design
Hraško, Branislav ; Novák, Lukáš (referee) ; Koch, Miloš (advisor)
This diploma thesis evaluates the current state of a product developed by a company Kentico software s. r. o. called Kentico Kontent. Based on the analysis of the organization and the product is realized a proposal of a log management system designed for customers of the company which is currently not implemented in Kentico Kontent.

Distributed Brute Force Attacks Protection
Richter, Jan ; Čejka, Rudolf (referee) ; Lampa, Petr (advisor)
This project deals with analysis of brute force attacks focused on breaking authentication of common services (especially ssh) of Linux and xBSD operating systems. It also examines real attacks, actual tools and ways of detection of theese attacks. Finaly there are designed new mechanisms of coordination and evaluation of distributed brute force attacks in distributed environment. These mechanisms are then implemented in distributed system called DBFAP.

Determination of droplet velocity and size from high-speed imaging
Juroška, Jan ; Cejpek, Ondřej (referee) ; Malý, Milan (advisor)
In this bachelor thesis there was created a method of getting velocity and size of droplets form a video using computer vision. Velocity is obtained via PIVlab toolbox in matlab, wich uses Particle Image Velocimetry. Size is obtained via matlab code. Theoretical basis on wich this code was written is included in the theoretical part of this thesis. In practical part of this thesis, accuracy of this method was evaluated and the method was applied on a video of a real spray droplet flow.

Neural Network Based Edge Detection
Jamborová, Soňa ; Grézl, František (referee) ; Švub, Miroslav (advisor)
This work is about suggestion and implementation of the software for detection of edges in images using neurons network. It defines basic terms for this topic and focusing mainly at preperation imaging imformation for detection using nerons network. Describing and comparing different aproachings for using implemented software on synthetic and real set of images, including experiments.

Message Logging System
Vrzal, Miroslav ; Křivka, Zbyněk (referee) ; Zendulka, Jaroslav (advisor)
This master's thesis in the first part describes the AS/400 and its message system and concentrates especially on the following areas: predefinition of messages and their storing, types of messages and levels of their importance, work with variables included in message text and ways of sending messages. On the basis of AS/400 message system is designed and implemented message log system for the application loggin for Aegis. s.r.o. The analysis of the message log systems is also a part of the work. The syslog and syslog-ngused in UNIX systems are described, concerning types of messages, importance of messages and filtering and storing of messages. It further describes possibilities of application logging based on Java in the specific case of the Log4jutility. In the second part thesis describes own log message systems design and implementation.

Mobile Wood Splitter
Stuchlík, Jakub ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor´s thesis deals with the issues of the mobile wood splitter. The first part describes the basic division of splitters in the market. I am going to choose the most suitable solution for my assignment. In the second part I am going to focus on the calculation of strength and checking of chosen type of the splitter.
