Analysis of Attacks Using Web Browser
Olejár, František ; Michlovský, Zbyněk (referee) ; Drozd, Michal (advisor)
Different attacks guided from web servers using web browsers are being analyzed and described in this Bachelor's thesis. A simulation environment is used to simulate the attacks. The environment was created using Browserider, using the web server Apache 2 and a virtual machine as well. On the basis of the analysis, the application ExploitAnalyzer was developed and implemented and can successfully record process's actions as well as IRP requests sent during an attack onto a web browser.

Reduction of Computation Cost in libSVM Using String Kernel Functions
Kubernát, Tomáš ; Sehnalová, Pavla (referee) ; Michlovský, Zbyněk (advisor)
The goal of this thesis was to implement four string functions into the library libSVM . Then apply series of tests with variable parameters values affecting the individual string functions using the library and string functions. Using the results of experiments the speed and success of clasification of my implementation of string functions in library libSVM was compared with the implementation of string functions in program kernels . In this thesis there are also described procedures of all tests along with measured data and their graphical representation.

Ssh Attacks Detection on Netflow Layer
Marek, Marcel ; Barabas, Maroš (referee) ; Michlovský, Zbyněk (advisor)
This bachelor's thesis briefly describes the basic principles of SSH protocol, its architecture and used encryption. The thesis is mainly focused on datamining information from low-level network communication and usage of its results for attacks detection. It also describes dictionary attacks used on SSH service and with NetFlow shows further possibilities of increasing network security.

Honey-Pot: System for Attack Detection
Michlovský, Zbyněk ; Malinka, Kamil (referee) ; Cvrček, Daniel (advisor)
This thesis deals with the area of honeypots and honeynets. It defines their classification and contains detailed descriptions of their properties and features. It further elaborates on several freely available systems. The main focus is given to honeypot Nepethes that was being run for one month on an unfiltered Internet connection. A detailed analysis of the collected data is then given.

File Synchronization on 3 or More PCs
Nykrýn, Lukáš ; Michlovský, Zbyněk (referee) ; Jurnečka, Peter (advisor)
This document descripes the design and implementation of application for file sharing between multiple computers using an external drive. Application can be run on GNU/Linux and MS Windows. In Windows application performs synchronization at regular intervals. Under GNU/Linux offers extra choice to watch the status of files and immediately synchronize file after change. The whole system monitors and cares for all possible collision states of files that can arise.

Technical Analysis
Loub, Matěj ; Michlovský, Zbyněk (referee) ; Novotná, Veronika (advisor)
The main goal of the thesis "Technical analysis" is to analyze the issue of technical analysis itself, more specifically the CAMP model, which deals with optimizing the portfolio, then design a program to calculate it (generate the required results). This analysis corresponds to the structure of the thesis, while in the beginning of the work are mentioned an important theoretical basis. There is described the financial system, financial and capital markets in connection to the Burza cenných papírů Praha, a.s. and other major capital markets. In addition, I discuss the methodology of technical analysis, CAMP model and the source code and the description of Visual Basic. Then I use this methodology in practice and focus on the goal of the work. Finally I analyze the options, benefits as well as weaknesses of the CAMP model and my program in the Czech capital market conditions.
