National Critical Functions are defined as the functions of government and the private sector so vital to the United States that their disruption, corruption, or dysfunction would have a debilitating impact on either the Nation’s homeland security, economic security, public health or safety, or any combination of these. By transitioning from a sector-oriented approach to a functional approach to risk, CISA is better able to understand and mitigate cross-sector risks and dependencies. The National Critical Functions Initiative is CISA’s far-reaching effort to fundamentally evolve the way in which risks to the Nation’s critical infrastructure are identified, analyzed, prioritized, and managed.
Since the fall of 2018, CISA has worked with all 16 Sector Coordinating Councils (SCCs), Sector Specific Agencies (SSAs), and the State, Local, Tribal, and Territorial (SLTT) Government Coordinating Council (GCC) to identify a draft list of National Critical Functions. This draft list of National Critical Functions is currently in its final validation stages and publication is expected by April of 2019. Once this list is validated, CISA will perform risk analysis, dependency analysis, and consequence modeling for the purpose of creating a prioritized risk register to direct collaborative risk management efforts.
