Critical functions Критичні функції (ua)

activities or operations distributed across the political, military, economic, social, information, infrastructure (PMESII) spectrum, the discontinuance of which would lead to the disruption of services that a working system (for example, a state, its society, or a subsection thereof) depends on. Critical functions can be broken down into a combination of actors (for example, individuals or organizations), infrastructures (for example, ‘critical’ national power grids) and processes (for example, legal/jurisdictional, technical, political).
