HTTP Analyzer with Web User Interface
Rozsnyó, Tomáš ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
This work provides a description of the theoretical and implementation part of HTTP analyzer with a web interface. HTTP Analyzer processes and saves captured HTTP packets. HTTP Analyzer includes a client, whose task is to save analyzed logs to PostgreSQL database. Web interface provides the management of the PostgreSQL database and offers capability to readily and clearly see the statistics generated from the stored logs. Database management involves the manipulation of stored logs and administration of users accessing the web interface.

Diagnostics of GNU/Linux-Based Systems
Hofbauer, Martin ; Doležal, Jan (referee) ; Smrž, Pavel (advisor)
This bachelor thesis focuses on the creation of the light-weighted program, which collects and saves information from GNU/Linux-based systems. Designed and developed solution can also inform about errors in the operating system and its unusual behavior. The program aims at maximum reliability, isolation of individual parts, and ease of use. The theoretical part describes problems of already existing solutions and focuses on the system monitoring context. The practical part then describes program architecture and its implementation. The program was successfully deployed in the company BringAuto, which collaborated with the creation of this thesis. It turned out that the program is able to record information from the operating system without its big load. In case of partial system failure, the program helped with finding its causes.

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.

Log Analysis and Hardware Utilization
Kuchyňka, Jiří ; Homoliak, Ivan (referee) ; Očenášek, Pavel (advisor)
The goal of this thesis is to design and implement a system for long-term monitoring of the state of Linux systems located in a production environment. The thesis focuses mainly on situation in which the system does not have the ability to send the collected data for analysis over the network, so data collection must be completely automatic and data must be transferred from monitored systems to a central system for collection, analysis and visualization. A substantial part of the work is devoted to the design and implementation of a web application used to export data from monitored systems to the transmission medium and import them from it to the system for data collection. The resulting solution aims to simplify the collection of data from systems, previously performed directly by system administrators, so that it can be performed by anyone who can physically approach the monitored system and thus reduce the costs associated with monitoring these remote systems.

Log Analysis Using TeskaLab Platform
Kocinec, Patrik ; Jeřábek, Kamil (referee) ; Ryšavý, Ondřej (advisor)
This work describes the usage of machine learning methods for processing logging information on LogMan.io system. The work includes a description of methods of processing logging information for the purposes of security monitoring, as well as machine learning methods and principles of data processing. Subsequently, the work focuses on the introduction of the LogMan.io system and its components. Then, an application for processing logging information is designed and implemented on LogMan.io system, which uses machine learning methods to detect malign domains. When implementing the application for model training, several methods were used focusing on the accuracy of detection.

User tools to support automated functional testing of prototypes in product development
Grabovský, Štěpán ; Macháček, Jiří (referee) ; Svoboda, Radomír (advisor)
This work deals with develop of PC application to support automated testing of prototypes, which are developing in Honeywell International, Inc., ACS division in Brno. There was created a PC software witch executes testing process based on input script files. For select script files and specify other necessary information was designed a graphic user interface. Testing information are being presented in a program information control in real-time as the same as results of tests. The application also allow to users save the log file. The program has been realized in C# programing language.

Dohled firemní infrastruktury pomocí nástroje Zabbix s integrací log manageru ELISA
Jelínek, Roman
Jelinek, R. Monitoring of Company Infrastructure using Zabbix Tool with Integra-tion of ELISA Log Manager. Master's Thesis. Brno: Mendel University in Brno, 2023. This thesis deals with the creation of a monitoring system for a company's infrastructure. The monitoring system is implemented using the Zabbix monitoring tool, configured according to the organization's requirements. Furthermore, log files are analyzed using the ELISA log manager, and the logs are subsequently evaluated based on created rules. As part of this thesis, the integration of these two systems was configured to enable monitor alerts sent from the ELISA system within the Zabbix interface.

Log analysis of active network elements
Kajánková, Petra ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
The master thesis focuses on the issue of searching for malicious activity originating from authorized users who have permission to modify devices. The theoretical part first introduces the basic network model ISO/OSI, together with TCP/IP. It then focuses on the two most well-known logging protocols, the Syslog protocol and SNMP. The practical part of the work consists of the theoretical design and subsequent implementation of the program that is able to evaluate records of events occuring on individual network devices.
