Key points included:

1. Cascading effects: Due to strong interdependencies, attacks can quickly affect sectors far beyond the infrastructure initially targeted.
2. Electricity and telecommunications: Electricity has the greatest potential for cascading failures, as almost all sectors depend on it. Information technology and telecommunications form the nervous system of modern society. Today, almost everything requires both electricity and data connectivity.
3. Digital vulnerability: Digitalisation has made the economy more capable, but also more vulnerable. Critical functions therefore need locally controllable, isolated, or offline fallback systems.
4. European technological sovereignty: Greater independence is needed in critical hardware and software, cloud services, and supply chains.
5. Societal resilience: Germany has initiated a transition through new legislation, but countries such as Finland are further advanced in integrating government, businesses, emergency organisations, and the population into a comprehensive security approach.
