Simulation of communication part of modern industrial networks
Beneš, Pavel ; Blažek, Petr (referee) ; Fujdiak, Radek (advisor)
The thesis is focused on simulating of protocols from standard IEC 61850 in simulation tool OMNeT++. The theoretical part in the thesis deals with description of the field of operating technologies, supervisory control and data acquisition and protocols Tase-2/ICCP, IEC 61850, IEC 60870-5-104, DNP 3 and DLMS/COSEM. Next part deals with parameters influencing connection and description of simulation tools NS2/NS3, OPNET and OMNeT++. In the practical part there is created a network containing protocols from the standard IEC 61850 in the simulation program OMNeT++. Then in the network a end to end delay and packet loss with increasing traffic is measured.

Methodology of pentesting in industrial control systems
Slabý, Patrik ; Lukáš,, Petr (referee) ; Sedlák, Petr (advisor)
This diploma thesis deals with the design of a methodology for penetration testing of industrial control systems. This work aims to approach the issue of these systems, which has completely different priorities than information technology systems, and based on these parameters to then design a procedure and rules that should be followed by the subjects participating in the tests. The absence of a methodology for such a specific environment affecting cyberspace and physical space can have catastrophic consequences. The theoretical part deals with basic concepts and terminology important for information and cyber security, operational technologies, and penetration tests. The design then contains a description of the individual steps of the penetration testing methodology for industrial control systems.

IT/OT modular honeypot
Nečas, Martin ; Fujdiak, Radek (referee) ; Blažek, Petr (advisor)
V bakalářské práci byl realizován modulární a škálovatelný systém honeypotů zaměřený na IT a OT. Cílem bylo navrhnout a implementovat systém, který umožní snadné přidávání modulů reprezentujících komunikační protokoly a virtuální zařízení a silně zdůrazňuje modularitu. Honeypoty jsou nasazeny v kontejnerech a systém aktivně monitoruje komunikaci mezi těmito kontejnery a útočníky. Všechny komunikační aktivity jsou uloženy v centralizovaném logu pro důkladnou analýzu a monitorování.
