IoT Traffic Generation and Detection of Security Incidents
Pristaš, Ján ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
The main purpose of my bachelor thesis is to design and create operation generating system of IoT networks, creating security incidents and their detection. First part describes basic principles of IoT networks, SCADA systems and communication protocols IEC 60870-5-104 and DLMS/COSEM. Subsequently there are described industrial tools emulating operation of SCADA systems using investigated protocols. The next section describes the security of these systems, along with the risks they face. Based on this information, a tool was designed and implemented to simulate various types of attacks on SCADA systems and track their reactions. The last part of the work is devoted to the possibilities of detecting di erent types of attacks and how to protect the networks from them.

Traffic generator of industrial protocols
Šnajdr, Václav ; Blažek, Petr (referee) ; Martinásek, Zdeněk (advisor)
This bachelor thesis deals with generating data traffic of industrial SCADA protocols and their implementation into JMeter tool. This tool can be expanded with plugins. Three protocols DNP3, IEC61850 and IEC60870-5 are described in the theoretical part. The practical part is devoted to the design and implementation of the DNP3 protocol module and partly to the design of the IEC61850 protocol. The DNP3 module has been functionally tested. There is also an attempt to obtain the TASE.2 library.

Distributed Control System with Dynamically Evolvable Nodes on RPi Zero Platform
Szymik, Michal ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
This work focuses on the development of a distributed control system that runs on multiple Raspberry Pi Zero devices and enables dynamic reconfiguration of its topology. The platform is implemented in Python in the form of a runtime environment. This work also describes how to develop applications for this system and introduces a script that facilitates the installation of an application onto the system nodes. The system described works and a sample application demonstrates its functionality.

Monitoring system for gasification of wood chips
Vaško, Radim ; Bradáč, Zdeněk (referee) ; Štohl, Radek (advisor)
In my work, I am developing measuring application for monitoring gas quality. I explain the technological process of measurement by spectrometric sensors. I design an industrial cabinet with PLC. I’m explaining algorithms of program for PLC AMiT AMiNi4DS. I describe inner communication of system. I assemble device mechanically and electrically. I am then setting the system ready for use. I create SCADA project for application. I describe the general characteristic of SCADA systems and specific SCADA software Reliance 4.

Medium voltage substation automation using control system COM600 and standard IEC61850
Havelka, Tomáš ; Štaffa, Jan (referee) ; Háze, Jiří (advisor)
This work deals with problematic of standard IEC61850, mainly with chapter IEC 61850-9-2 LE which is commonly known as Process bus communication. There are described advanced tools of the control system COM600 with detail description of their configuration in this work. It also deals with configuration of IEC 61850-9-2 LE with Relion family protection relays and its implementation to the control system COM600. The main aim of this work is focused on configuration of IEC 61850-9-2 standard with protection relays, configuration and detail description of COM600 advanced tools, description of Logic processor, further custom design and appliaction configuration global reset of Logic procesor in control system COM600.

CIP industrial protocol simulation
Molent, Michal ; Musil, Petr (referee) ; Blažek, Petr (advisor)
The thesis is about industrial automatic CIP protocol, which belongs to SCADA systems. The first part is focused on basic principles of CIP protocol and on analysis of two protocols (EtherNET/IP and DeviceNet), which are based on CIP protocol. The second part deals with designing scenarios for a simulation. The simulation of one-way communication, two-way communication with help of reads from the console and two-way real time communication between Raspberries PI 3B+. The third part deals with a realization of the simulation, a start-up and a function of predefined scenarios and graphic interface. The fourth part deals with analysis network communication in situations, which occur during a protocol EtherNet/IP simulation.
