Fact Sheet: EO 13636 Improving Critical Infrastructure Cybersecurity and PPD 21 Critical Infrastructure Security and Resilience
The Department of Homeland Security (DHS) leads the federal government’s efforts to secure our nation’s critical infrastructure by working with owners and operators to prepare for, prevent, mitigate, and respond to threats. While DHS plays a central role, the Department cannot do this work alone. Public-private partnerships are essential. It is through partnerships where the Department continues to see new value and positive impact in mitigating and rapidly responding to crises.
