Critical Infrastructure
Critical Infrastructure refers to the essential physical and cyber systems, assets, and networks that are so vital to a country that their disruption or destruction would have a devastating impact on national security, economic stability, public health, or safety.

TECHNICAL DEFINITION
Critical Infrastructure encompasses a nation's core physical and cyber assets, including energy, water, telecommunications, healthcare, transportation, and financial services, whose incapacitation would severely debilitate national security, governance, economic function, and societal well-being.
BACKGROUND
The Cybersecurity and Infrastructure Security Agency (CISA), headquartered in Arlington, Virginia, is a component of the United States Department of Homeland Security (DHS) responsible for cybersecurity and infrastructure protection across all levels of government, coordinating cybersecurity programs with U.S. states, and improving the government's cybersecurity protections against private and nation-state hackers.
