Protecting Critical Infrastructure and Critical Information Infrastructure

Abstract Regardless of how you define critical infrastructure, and critical information infrastructure as part of it, these are elements necessary for the functioning, integrity and security of a digitised society. Mapping what is critical (information) infrastructure and assessing the risks and hazards to it is a first step towards protection, along with a risk decision to either mitigate, remediate or accept the risk. For the protection of critical (information) infrastructure it is necessary to coordinate efforts and collaboration between sectors, which are often interdependent. Public-Private-Partnerships (PPP) and cooperation within organizations such as NATO and the EU are essential.
