Compare of Contemporary Open Source Content Management Systems
Martinák, Lukáš ; Stryka, Lukáš (referee) ; Jaša, Petr (advisor)
This thesis is about comparing open source content management systems. There is a description of the content management system and there are three chosen systems to compare - Drupal, Joomla! and WordPress. The same web project containing multiple users, blogs, discussion forum and e-shop is consequently implemented in each of them. Systems are compared in many phases of development cycle of web applications - comparison includes introduction, installation, managing users, creating web structure, changing design, extendability, user interface, managing backups, actualization, localization and more. There is also a chapter discussing SEO and web application testing.

Checking SQL Code Properties
Bali, Filip ; Bartík, Vladimír (referee) ; Rychlý, Marek (advisor)
This thesis focuses on checking the properties of SQL code based on static analysis using predefined rules. The rule represents a basic element of the check. The user can define their own rule and include it in the check. A rule usually contains a set of conditions that are contained in an algorithm that checks nodes in an abstract syntactic tree. Abstract syntactic tree is created from an input SQL statement and customized so that rules can be applied over its nodes. If the rule detects an error, then it can generate a report. These reports are then displayed on the selected output. Based on the thesis, an open source program in the Python3 programming language was implemented. This program is publicly available.

Motionless Presence Detection of Humans
Szabó, Tomáš ; Dolejška, Daniel (referee) ; Pluskal, Jan (advisor)
Tato práce má za účelem nalezení generického řešení pro implementaci detekce osob v chytré domácnosti. Jednoduchá implementace za pomoci PIR sensorů je sice efektivní, ale při delší nečinnosti v místnosti jako práce na počítači nebo sledování televize není šance detekce změny v prostoru. Díky radaru fungujícím na bázi milimetrových vln jsme schopni říct zda osoba v místnosti skutečně pořád je. Existující komerční řešení je drahé a pro některé kouty světa nedostupné, jelikož produkt v dané zemi nemusí být povolen k prodeji. Řešením je implementace radaru tak, aby mohl fungovat jako samostatná jednotka v propojení s vývojovou sestavou, tak jako jedinec v rámci množiny senzorů. Jako testovací prostředí je vybráno prostředí NES@FIT pro rozsvícení světel při detekci osoby v mistnosti, kde je realizace prozatím řešena PIR senzory.

Implementation of a monitoring tool into a corporate network
PANUŠKA, Václav
This bachelor thesis describes the design and implementation of a monitoring tool into corporate networks. Monitoring tools play an important role for the administrator who use them to identify network problems. Using monitoring tools, we collect individual statuses of the metrics we have predefined, such as device availability, interface traffic, disk usage, etc. This information is then used by the administrator for a timely response to problems in the computer network. The theoretical part describes computer networks and protocols that use by monitoring tools most often. The next section describes the Centreon open source solution, which is implemented as a monitoring tool within a corporate network and describes the possibilities and functions of the Centreon monitoring tool. The practical part of the thesis includes implementation of the Centreon monitoring tool into a corporate network.

Smart home model
Kaniok, Vojtěch ; Jirgl, Miroslav (referee) ; Sýkora, Tomáš (advisor)
This bachelor thesis deals with exploration of possibilities in regard to automatic integration of devices into Home Assistant and creating a demonstration model of home automation. The theoretical part of this work presents the MQTT protocol, presentation containing description of functionality and comparison with the HTTP protocol. Furthermore, explanation of specific concepts for MQTT such as QoS, types of messages, possibilities of filtration etc.Introduction of the ZigBee communication standard. Following section introduces Open source platform Home assistant, description of architecture, various options of integrating devices, characterization and disadvantages of particular types of installations. Subsequently, I will describe alternatives of MQTT integration in Home Assistant and compare advantages and disadvantages. In the last section of this paper the reader is familiarized with final results, description of MQTT discovery protocol, test of ESP HOME platform and verification of functionality of automatic integration

Comparison of open source and proprietary software security
Popov, Dmytro ; Pokorný, Jan (advisor) ; Souček, Martin (referee)
The main focus of this bachelor thesis is to compare open source and proprietary software security and to ascertain which software provides the best possible protection for information. The thesis commences with a definition of the frequently used terms in the thesis and is followed by an outline of how software evolved and the history of computer security. The main focus of this work study examines in detail which software type provides better security for end users, government agencies and commercial companies. The theoretical arguments presented are supported by relevant statistics and examples. This thesis also describes the algorithms used to measure and compare the different software security and databases that are used to store information security related data.
