Unified Software Database for RPM Based Systems
Šilhan, Jan ; Očenášek, Pavel (referee) ; Zelený, Jan (advisor)
V GNU/Linuxovém prostředí je nepřeberné množství možností, jak instalovat aplikace. V dnešní době existuje spousty nástrojů, které mají na starost různé části systému. Linuxové distribuce mají hlavního správce balíčků a populární programovací jazyky mají také vlastního správce balíčků. Všechny tyto nástroje si udržují informace o nainstalovaném softwaru, a proto si každý z nich spravuje vlastní databázi s redundantními metadaty o balíčcích. Záměrem této práce je analyzovat úložné prostory, identifikovat případy užití správců balíčků v distribuci Fedora a následně navrhnout a implementovat jednotnou cen- trální softwarovou databázi na systému.

An Application Utilizing esmska Plugins for Sending SMS Messages via Web Gateways
Marton, Dominik ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This thesis describes the design and implementation of a console application, that utilizes esmska JavaScript modules to enable sending SMS messages from inside of user scripts via web gateways without CAPTCHA security plugin, and of a web service with REST interface making this application accessible remotely. Both are primarily made with the purpose of running on network devices with OpenWrt operating system while trying to minimise memory consumption. The whole solution is written in C with the help of libcurl library, embedded JavaScript interpreter Duktape and standard C library uClibc.

Implementation of External Authentication Modules for nginx
Kameníčková, Petra ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This bachelor's thesis describes the process of design and development of authentication modules for nginx web server. These modules are used for enrollment of nginx-based applications and services into FreeIPA environment. The first part of the thesis explains the basics of FreeIPA and nginx architectures and principles of Kerberos and PAM authentication mechanisms as well. The second part of the thesis solves the practical problems - existing Apache modules analysis, nginx design description and implementation details. The last part describes confi guration requirements and possible enhancements.

Analysis of Private Information from FAT32
Križan, Lukáš ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
The aim of this thesis was to create an application which can search for and recover specific files in the file system FAT32, and subsequently extract sensitive information from these files. The first part of this thesis describes the principles underlying FAT32, and focuses on how the analysed applications store information. The second part outlines the application and describes its implementation and simulations.

Application for the Data Processing in the Area of Evolutionary Biology
Radakovič, Lukáš ; Burgetová, Ivana (referee) ; Očenášek, Pavel (advisor)
This Bachelor’s thesis describes the design and implementation of the application that has the task to verify the accuracy of the algorithm. Purpose of the algorithm is to analyze mechanisms used in the creation of the phylogenetic tree. The application allows users to specify different parameters of phylogenetic tree, its generation and subsequent analysis using an algorithm. Results of the analysis are written to the output file, giving the user the option of setting file path. Studied algorithm correctly estimates the participation of specific mechanism in the tree formation. Estimates of the absolute and relative share of changes in chromosome number and genome size are less than accurate results.

Sensor Pattern Noise Analysis and Identification
Král, Benjamin ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This work is about extraction of sensor pattern noise of digital camera which is additive noise that is present in every digital photograph and which is unique for every camera. Suitable sensor pattern noise extraction methods are discussed for noise extraction and comparation with aim to find out with which camera the digital picture was taken. Best method is implemented as an application. The work describes few experiments that are reviewing the application performance based on many different photographs given to the application.

Time-Based Account Policies in FreeIPA
Láznička, Stanislav ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
Tato práce se zabývá běžnými problémy časových politik, které jsou využívány v rámci procesu přihlašování uživatelů. Jsou rozebrána řešení v některých jiných současných systémech. Dále je čtenáři představen projekt pro správu identit FreeIPA, autor se zaměřuje hlavně na správu uživatelů a politiky pro jejich autorizaci. Je také představen projekt SSSD se zaměřením na jeho propojení se systémem FreeIPA. Po vytvoření návrhu řešení problému časových politik je tento návrh implementován do systémů FreeIPA a SSSD.
