Simulace komunikační části moderních průmyslových sítí
Beneš, Pavel ; Blažek, Petr (oponent) ; Fujdiak, Radek (vedoucí práce)
Tato práce je zaměřená na simulaci protokolů z normy IEC 61850 v simulačním nástroji OMNeT++. Teoretická část práce se zabývá popisem oblasti operačních technologií, dispečerského řízení a sběru dat a protokoly Tase-2/ICCP, IEC 61850, IEC 60870-5-104, DNP 3 a DLMS/COSEM. Dále se tato část zabývá parametry ovlivňující spojení a popis simulačních nástrojů NS2/NS3, OPNET a OMNeT++. V praktické části je vytvořena síť obsahující protokoly z normy IEC 61850 v simulačním programu OMNeT++. Na té je následně odměřeno jednosměrné zpoždění a ztrátovost paketů s narůstajícím provozem.

Gathering information about industrial equipment using a search engine
Danko, Krištof ; Fujdiak, Radek (oponent) ; Pospíšil, Ondřej (vedoucí práce)
The work is focused on operating technologies, specificaly on the security of PLC (programmable logic controller), and obtaining information using device search engines. The types and parts of industrial networks, which are the main segment of operational technologies, and the search engines such as Shodan, Censy, BinaryEdge, and Zoomeye are described. These search engines are compared based on available information and industry protocols Siemens S7, Modbus, Ethernet / IP, and DNP3. In addition to comparing search engines, this work aims to create an application that can download results from the Shodan search engine via the Shodan API and store them in a database. Another point of work is the connection of own PLC, to determine the time of PLC appearing in search engines.

Cyber security testing in an environment of operational technology
Kuna, Erik ; Pospíšil, Ondřej (oponent) ; Paučo, Daniel (vedoucí práce)
The topic of this work is security testing in connection with operational technology networks. The theoretical part covers description of operational technology, analysis of the current state of security in such networks and the methodology for penetration testing in this context. A section is devoted to protocols relating to said networks, comprising their characteristics, comparison of the same and related advantages and disadvantages. The theoretical part aids comprehension of the practical section, which details design and implementation of a suitable environment for testing and performing security in ICS/SCADA. Therein, emphasis is placed on security issues that pertain to the ModBus protocol.

IT/OT modular honeypot
Nečas, Martin ; Fujdiak, Radek (oponent) ; Blažek, Petr (vedoucí práce)
The bachelor's thesis created a modular and scalable honeypot system focusing on IT and OT. The goal was to design and implement a system that allows the easy addition of modules representing communication protocols and virtual devices while strongly emphasising modularity. The honeypots are deployed in containers, and the system actively monitors the communication between these containers and the attackers. All communication activities are stored in a centralised log for thorough analysis and monitoring.
