Open data gathering and how to use it in cybersecurity
Gašparová, Marta ; Malina, Lukáš (referee) ; Paučo, Daniel (advisor)
This thesis deals with Data Gathering from Open Sources which can be used in Cyber Security; an analysis of the OSINT tools; a creation of a Data Gathering Tool itself. The theoretical part of the thesis explores Data Gathering within the framework of Ethical Hacking and in which phase of Penetration Testing the Data Extraction is crucial. Following the analysis of the OSINT tools the Practical part of the thesis examines the Created Tool itself which was written in Python programming language. Via API interface the Tool allows interaction with other OSINT tools such as Censys, crt.sh or DNSDumpster. After entering the IP address or domain of the target company the Tool is able to search for basic information such as location, DNS names and running services. Based on the target URL the Tool is able to show both present and absent HTTP security headers on the given website and also based on the entered domain it can search for SSL/TLS certificates, subdomains and emails of the target company.

An Application with HAWK Controller
Klíma, Jaroslav ; Štohl, Radek (referee) ; Jirgl, Miroslav (advisor)
The target of this bachelor’s thesis is to execute a connection between the HAWK controller by the Centraline/Honeywell company and crane models through the MODBUS/TCP communication protocol, including a demonstration of its functionality and creating a visualisation. Programmable machines SIEMENS S7-1200 were used to control the models. The first part of the thesis is dedicated to describing the HAWK controller and its communication options in its basic configuration. The second part is dedicated to the most utilized functions and terminology of the COACHAX development environment thanks to which the MODBUS communication is executed and a demonstration application is created. The practical part first offers a basic exercise to demonstrate the communication of a programmable machine and the HAWK controller through MODBUS/TCP and then an application which creates a shell system surface, unlike the programmable machines, and offers advanced options of controlling the model and formation of basic functional statistics.

Control of algal bioreactors
Rek, David ; Naď, Martin (referee) ; Máša, Vítězslav (advisor)
The bachelor’s thesis discusses the matter of cultivation of microalgae in an artificially altered environment – bioreactor. The aim of the thesis is to determine and present the factors influencing the growth of microalgae and to find means of automated regulation of such factors. Nowadays, the majority of bioreactors are laboratory ones and are mostly being operated manually. The recent increase in demand for this technology results in many pilot-plant tests with a wide variety of microalgae. Tests such as these will be required to be automated to serve properly in future research. The thesis is based on professional literature and articles. The first part is to familiarize the reader with the wide number of potential applications of microalgae technology in various fields, such as the food industry, water treatment or separation of CO2 from ambient air or waste gas. The next segment presents the factors influencing the growth of microalgae and lastly the system of required equipment and sensors for automated operation is described. The bachelor’s thesis summarizes the important information necessary for the construction and unattended operation of microalgae bioreactor with respect to maximalization of productivity.
