Cyber attacks on critical infrastructures and satellite communications

The cyber-attack on the Ukrainian positioning network at the beginning of the ongoing Russia-Ukraine war demonstrated how the branching of satellite connections can have severe repercussions for communication systems. While ground-based networks are changing, the vulnerability of critical infrastructure to cyber-attacks and technical failures has become a serious concern. As cyber attackers are increasingly targeting industrial control systems rather than stealing data, attacks have become more sophisticated and significant. Future connectivity to 5 G networks, the entry of new private players in this sector, and the economic growth of emerging countries will further increase the attack surface of the space sector. A risk-based approach is therefore needed to increase protection and resilience against cyber-attacks. This requires a comprehensive understanding of the technologies and their vulnerabilities, as well as the ability to quickly develop solutions to counter attacks. Responding effectively with legal and policy means is essential to adapting to changes and to providing continuity and security of services. This paper highlights the main qualities of communication technology, its vulnerabilities, and the critical challenges to achieving cyber resilience. It identifies significant assets, defence solutions, and legal and policy aspects that should be further researched to enhance the cyber resilience of European assets.
