Each national or international strategy and policy identifies different categories of sectors that are considered to offer vital services and thus require protection. A 2008 survey examined the policies of 25 countries and identifies as the most frequently mentioned the following sectors:

  • Banking and Finance
  • Central Government / Government Services
  • (Tele-)Communication / Information and Communication Technologies (ICT)
  • Emergency / Rescue Services
  • Energy / Electricity
  • Health Services
  • Food
  • Transportation / Logistics / Distribution
  • Water (Supply)

The study comments that "these are the core sectors of modern societies, and possibly the areas where a large-scale interruption would be most devastating" [1].
