Cyber security for power engineering
Sedláková, Dáša ; Kohout, David (oponent) ; Mlýnek, Petr (vedoucí práce)
Due to the IT and OT networks convergence, industrial systems are becoming vulnerable to different forms of security threats including rapidly growing cyber-attacks. Thesis is focused on an analysis of security recommendations in IEC 62351, vulnerability testing of industrial communication protocols (e.g., IEC 61850) and mitigations proposal. An ATT&CK framework for ICS was chosen to become a methodology base for vulnerability testing. ATT&CK tactics and techniques were used to practically test vulnerability scans, SMV time synchronization, GOOSE spoofing, MMS Man in the Middle and ICMP Flood attacks. Attacks tested were evaluated with a risk analysis. Subsequently, mitigation measures were proposed on several levels (OT, IT, perimeter and physical level).
