Implement Security Service for Preventing Internet Attacks
Fajkus, Karel ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
The main purpose of this work is to design and implement a system, that would allow to ban users based on their actions. Currently, cyber attacks have become very common, which leads to a necessity to develop great application and system protections. This project offers a solution, that could decrease a number of cyber attacks, and also prevent banning common users because of the same public IP address as attacker.

Industrial data collection system
Hvizdák, Lukáš ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
The master thesis focuses on the design and implementation of data collection from production using a PLC into an SQL database located in the cloud and subsequent visualization. The work describes the applicable communication protocols MQTT and OPC UA with the fact that the protocol MQTT was selected. It deals with securing data transfer from the line to the cloud using the TLS protocol. The individual cloud services and their possibilities for data collection are described here. The work deals with the possibilities of data visualization using existing open source solutions and the differences between them. I describe the possibilities of modifying the open source environment of the Grafany project. Real dashboards from production are presented. The data collection system was deployed in two plants for testing.

Application Service and Server Monitoring
Pleško, Filip ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
This bachelor thesis addresses an issue of monitoring servers and server aplications. The goal is to simplify this monitoring and make it more efficient. To do so, we used ELK stack. With the use of this stack we achieved to easily read from log files and show usefull informations from them.

Performance Monitoring of MES PHARIS
Ondráček, Aleš ; Hruška, Martin (referee) ; Smrčka, Aleš (advisor)
This diploma thesis deals with the performance monitoring of automated development processes and performance testing of the MES PHARIS system. The main scope of thesis is the collection of data on tasks performed on automation servers DevOps and Jenkins, processing of this data and their subsequent visualization. The second part of the diploma thesis deals with the processing of data from performance testing and their appropriate representation using visualization. The core technology that is used is ELK Stack.

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 management ELK stack
SLAVÍK, David
This work describes problems with computer logs and how to treat them. The main goal of this work is to show how to collect, transform, save, and explore logs created by an application or system. It presents the log management solution named ELK stack that consists of three main components Elasticsearch which is a NoSQL database and search engine, Kibana used as a graphical user interface for viewing, analyzing data also as creating dashboards. Logstash is a part of the stack that transforms and prepares the message structure for the Elasticsearch. An additional component is a beat used for collecting the data from servers. Part of this work also includes instructions on how to install, configure and create a workspace with data. The result of this work should be helpful for companies struggling with logs to implement their own log management solution.
