What does PPD-21 address?

PPD-21, or Presidential Policy Directive 21, specifically addresses the security and resilience of critical infrastructure in the United States. This directive emphasizes the importance of a coordinated national approach to protecting infrastructure sectors, which are essential to the nation’s economy, security, public health, and safety.

PPD-21 recognizes various infrastructure sectors, including energy, transportation, and communications, and highlights the need for diverse stakeholders—government agencies, private sector partners, and other entities—to collaborate in enhancing the security and resilience of these systems against both physical and cyber incidents.

While national security threats, employee privacy concerns, and environmental protection measures are certainly important topics, they are not the primary focus of PPD-21. Rather, this directive specifically concentrates on ensuring robust practices to safeguard critical infrastructure, positioning it as a key component of national stability and security policy.
