This project is funded by the National Defence Technology Center (NFC) and conducted in collaboration between ITU, SDU, and DBI. It examines Denmark’s preparedness to defend against cyberattacks on critical infrastructure, with a particular focus on telecommunications. Based on 27 interviews with Danish and Ukrainian stakeholders, the report demonstrates how cyberattacks on telecom systems can disrupt essential societal functions and trigger cascading effects across sectors such as healthcare. Drawing on lessons from Ukraine, the project identifies key cyber threats, systemic vulnerabilities, and the need for multi-layered zero trust strategies, strong organisational practices, and cross-sector collaboration.
