Tallinn University of Technology

Antonio Carlo, the PhD student of Information and Communication Technology, will defend his PhD thesis "The Space-Cyber Nexus: Ensuring the Resilience, Security and Defence of Critical Infrastructure" in the Department of Software Science on June 20, 2024, starting at 13:00. The defense will take place in room ICT-315 (Akadeemia tee 15a, ICT building of TalTech) and can be also followed via Zoom.

Ever since the launch of the first artificial satellite in 1957, the cyber and space domains have been closely intertwined. This interdependence has been acknowledged by international organisations like NATO, which declared cyberspace and outer space as operational domains. Space is crucial for managing critical infrastructure globally, with most of it depending on satellite systems. The thesis aims to address how space infrastructure can be secured and defended from cyber incidents and how institutions can ensure the resilience of the cyber and space domains. The author uses qualitative and quantitative methods as well as tailored interviews to analyse the risks and vulnerabilities of space infrastructures and proposes recommendations to improve their resilience and governance. The thesis also discusses measures to address crises in space and cyberspace, and the potential of emerging technologies to enhance the security of satellite systems. Despite vulnerabilities, the author concludes that the opportunities of linking space and cyber capabilities offer significant growth for global security, resilience, and defence.

The thesis is published in the Digital Collection of TalTech Library.

Supervisor Dr. Adrian Nicholas Venables and co-supervisor Prof. Dr. Katrin Merike Nyman-Metcalf.
