Cyber-environment for systems of ICS/SCADA type
Váňa, Martin ; Blažek, Petr (referee) ; Fujdiak, Radek (advisor)
The thesis explores the problematics of cyber environment for the ICS/SCADA systems. First, shorter section is mainly focused on general introduction into the ICS/SCADA systems and their inner workings. Communication model of a general SCADA system and its foundational elements are explained. It is mainly theoretical passage and it serves as an introduction. It is necessary for understanding the second part which is mainly practical. The appropriate system is chosen as a first thing in the practical part of the thesis for the implementation of the whole project. There are defined criteria on which the system itself is implemented. Following that the system itself is implemented under a framework called openMUC and it is tested with help of the simulators according to the objective of the thesis.

Generator for simulation of SCADA attacks
Hudec, Jan ; Fujdiak, Radek (referee) ; Blažek, Petr (advisor)
Output of this bachelor’s thesis is an attack generator aimed on IEC 61850 protocol using the libpcap library. Part of the output is also a simulation of devices which are normally present in SCADA systems. Theoretic part aims to explain protocols DNP3, IEC 60870 and IEC 61850 more in-depth and further focus is on the attacks. Practical part contains attack implementation that aim on communication between SCADA units, more precisely on GOOSE and Sampled Values frames. Simulated devices generate this communication using the libiec61850 library. Attacks are aimed on that communication.

Energy testbed security
Zatloukal, Zdeněk ; Blažek, Petr (referee) ; Bohačík, Antonín (advisor)
The topic of the thesis is focused on the energy testbed security. The main objective of the work is the implementation of secure data communication of IEC 60870-5-104 protocol in the transmission system testbed according to the standard ČSN EN 62351. Furthermore, a comparison of secured and unsecured communication is included with testing of selected vulnerabilities. Subsequently, control functions related to testbed security were implemented in the control interface.

IEC 61850 industrial communication simulator
Srp, Jakub ; Pospíšil, Ondřej (referee) ; Blažek, Petr (advisor)
This thesis is focused on IEC 61850 communication protocols SMV, GOOSE and MMS and their implementation in SCADA systems. There is a simulator, run on Raspberry Pi, that generates data according to IEC 61850 and transmits the data using protocols in question. The simulation consist of various virtual devices e.g. surge protection, undervoltage protection, circuit breaker, disconnector, HMI. The MMS protocol is used for station control. Simulation can be user-defined from textual configuration file.

Identification of Device Availability in Technological Networks
Vodehnal, Stanislav ; Mlýnek, Petr (referee) ; Škorpil, Vladislav (advisor)
This diploma thesis deals with the monitoring of network elements of technological networks and distribution systems. There are described reasons why and what kind of values we want to monitor. Three monitoring systems are then selected, described their properties and functions. Based on their merits, one system for deploying the test environment is selected. The practical part is the configuration of the selected system and its subsequent deployment to the network.

Testing Communication via IEC 61850 and GOOSE between ABB and Siemens Protections
Vavreczky, Gábor ; Palát, Jan (referee) ; Orságová, Jaroslava (advisor)
The main objective of this thesis is to examine the possibility of cooperation of IEDs from ABB and Siemens in accordance with IEC61850. The aim is to create and test a workflow, after which protection relays from ABB and Siemens will communicate with each other via GOOSE messages. This paper provides a description of the international standard IEC61850, as a theoretical basis. Describes in detail the configuration of protection relays SIPROTEC 7SA610 according to IEC61850. Work provides a description of the configuration tools PCM600 and IET600 which are used for configuration of protection relays RELION® REF615 by ABB. In the final part of the work experiences that are written in collaboration used protection.

Drivers in PLC TC700/Foxtrot for feeder protection REF630/REF615
Till, Přemysl ; Bradáč, Zdeněk (referee) ; Štohl, Radek (advisor)
This thesis deals with communication within industrial systems, specifically using standard IEC 61850. The theoretical part contains a list of useful resources detailing IEC 61850 and a brief summary of the data model and model of vertical communication defined by the standard. In the practical part, a library for vertical communication between a Tecomat Foxtrot or TC700 PLC and an IEC 61850 conforming device was designed and created. It provides function blocks for establishing a communication channel, reading and writing data using the standard. Its functionality was tested using a feeder protection and control REF630 from ABB.

Testing of the relay communication according IEC 61850
Uchytil, Tomáš ; Topolánek, David (referee) ; Toman, Petr (advisor)
This thesis contains an overview of a new standard IEC 61850. Parts of the standard are described particularly. More space is devoted to the analysis of communication in substations and to features of horizontal GOOSE messages. The other part is devoted to testers of protection and their use in testing of communication in substations according with IEC 61850. The last part is a practical example of using the tester and software for communication network monitoring and measurement of reaction of the system which is controlled with GOOSE messages.
