Fact Sheet: Executive Order on Cybersecurity / Presidential Policy Directive on Critical Infrastructure Security and Resilience [open pdf - 159KB]
"Critical infrastructure -- both physical and cyber -- is the backbone of America's national security and economic prosperity. The Nation's critical infrastructure is diverse and complex. It includes distributed networks, varied organizational structures and operating models (including multi-national ownership), interdependent functions and systems in both physical space and cyberspace, and governance constructs that involve multi-level authorities, responsibilities, and regulations. Critical infrastructure faces a variety of risks to its security and ability to function, including manmade acts of terror, extreme weather events, other natural disasters and cyber attacks. Our country's reliance on cyber systems to run everything from power plants to pipelines and hospitals to highways has increased dramatically, and our infrastructure is more physically and digitally interconnected than ever. Yet for all the advantages interconnectivity offers, critical infrastructure is also increasingly vulnerable to attack from an array of cyber threats. It is imperative that we, as a country, take more action to strengthen our national policy on critical infrastructure security and resilience, and that includes measures to strengthen cybersecurity. Because the majority of our critical infrastructure is owned and operated by private companies, the public and private sectors have a shared responsibility to reduce the risks to critical infrastructure through a stronger partnership."
