"We depend upon cyberspace for daily conveniences, critical services, and economic prosperity. At the U.S. Department of Homeland Security, we believe that cyberspace can be made secure and resilient. DHS works with key partners across the Federal government, State and local governments, industry, and the international community to identify and manage national cybersecurity risks. The DHS Cybersecurity Strategy sets out five pillars of a DHS-wide risk management approach and provides a framework for executing our cybersecurity responsibilities and leveraging the full range of the Department's capabilities to improve the security and resilience of cyberspace."
