Critical infrastructure describes the physical and cyber systems and assets that are so vital to the United States that their incapacity or destruction would have a debilitating impact on our physical or economic security or public health or safety.  The nation's critical infrastructure provides the essential services that underpin American society.

Managing Risk Through Collaboration

Critical infrastructure must be secure and able to withstand and rapidly recover from all hazards. Proactive and coordinated efforts are necessary to strengthen and maintain secure, functioning, and resilient critical infrastructure – including assets, networks, and systems – that are vital to public confidence and the Nation’s safety, prosperity, and well-being. This endeavor is a shared responsibility among Federal, state, local, tribal, and territorial entities, and public and private owners and operators of critical infrastructure.

Leading the National Effort

The Department of Homeland Security provides strategic guidance to public and private partners, promotes a national unity of effort, and coordinates the overall Federal effort to promote the security and resilience of the nation's critical infrastructure.

November is Critical Infrastructure Security and Resilience Month.

What can you do to make our Nation stronger and more resilient?

The Federal Aviation Administration (FAA) is warning drone owners and operators they may face significant fines if they interfere with emergency response operations in the areas affected by Hurricane Florence. Many aircraft that are conducting life-saving missions and other critical response and recovery efforts are likely to be flying at low altitudes over areas affected by the storm. Flying a drone without authorization in or near the disaster area may unintentionally disrupt rescue operations and violate federal, state, or local laws and ordinances, even if a Temporary Flight Restriction (TFR) is not in place. Allow first responders to save lives and property without interference.
