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.
On November 16, 2018, President Trump signed into law the Cybersecurity and Infrastructure Security Agency Act of 2018. This landmark legislation elevates the mission of the former National Protection and Programs Directorate (NPPD) within DHS and establishes the Cybersecurity and Infrastructure Security Agency (CISA). CISA coordinates security and resilience efforts using trusted partnerships across the private and public sectors, and delivers technical assistance and assessments to federal stakeholders as well as to infrastructure owners and operators nationwide.
For Infrastructure Security, CISA's main focus areas include:
- Providing free tools and resources for government and private sector partners
- Facilitating Critical Infrastructure Vulnerability Assessments
- Strengthening security and resilience across the chemical sector
- Providing training, encouraging information sharing, and fostering sector partnerships and international engagement
