The conference targeted new security threats to critical infrastructure in different fields with a particular focus on digital and telecommunications. We discussed connectivity as an essential requirement for national security and vulnerability to disruptions of communication infrastructure. Following best practices, we also examined practical solutions based on government and private sector cooperation. The expert workshops on Friday, September 22, dove deeper into secure high-capacity critical communications infrastructure and discussed its cybersecurity, public procurement, or Dedicated Networks for First Responders, Public Protection, and Disaster Relief (PPDR).
