Supporting Policy and Doctrine


CISA leads the federal effort to help safeguard the Nation’s critical infrastructure from both cyber and physical threats and vulnerabilities. Infrastructure security efforts are largely voluntary, in collaboration  with other government and private sector stakeholders that own or operate the majority of critical infrastructure in the Nation.

The strategy and concepts in the National Infrastructure Protection Plan (NIPP) 2013 guide DHS in its execution of Presidential Policy Directive 21: Critical Infrastructure and Resilience, which calls on the Federal Government to advance a unified national effort to strengthen and maintain secure, functioning, and resilient critical infrastructure.

The NIPP identifies 16 critical infrastructure sectors that compose the assets, systems, and networks, whether physical or virtual, so vital to the United States that their incapacitation or destruction would have a debilitating effect on security, national economic security, national public health or safety, or any combination thereof. These sectors include everything from transportation and energy to food and agriculture and finance and nuclear infrastructure.

CISA supports many other key infrastructure security policies and doctrines. For instance, CISA’s Office for Bombing Prevention has a leading role in implementing the National Counter-IED policy, which is articulated through Presidential Policy Directive 17 (PPD-17): Countering Improvised Explosive Devices (IEDs). PPD-17 guides our nation’s efforts to secure the U.S. and its allies, partners, and interests from IEDs and enhance the ability to prevent, protect against, respond to, and mitigate the use of explosives against critical infrastructure, the private sector, and federal, state, local, tribal, and territorial entities.
