Introduction

The American people are increasingly dependent upon the Internet for daily conveniences, critical services, and economic prosperity. Substantial growth in Internet access and networked devices has facilitated widespread opportunities and innovation. This extraordinary level of connectivity, however, has also introduced progressively greater cyber risks for the United States. Long-standing threats are evolving as nation-states, terrorists, individual criminals, transnational criminal organizations, and other malicious actors move their activities into the digital world. Enabling the delivery of essential services—such as electricity, finance, transportation, water, and health care—through cyberspace also introduces new vulnerabilities and opens the door to potentially catastrophic consequences from cyber incidents. The growing number of Internet-connected devices and reliance on global supply chains further complicates the national and international risk picture. More than ever, cybersecurity is a matter of homeland security and one of the core missions of the U.S. Department of Homeland Security (DHS).

At DHS, we believe that cyberspace can be secure and resilient. We work every day across the Department and with key partners and stakeholders to identify and manage national cybersecurity risks. We do this by adopting a holistic risk management approach. Like every organization, no matter how big or small, we must minimize our organizational vulnerability to malicious cyber activity by protecting our own networks. DHS also has broader responsibilities to protect the larger federal enterprise and improve the security and resilience of other critical systems. At the same time, we seek to reduce cyber threats by preventing and disrupting cyber crimes, and to lessen the consequences of cyber incidents by ensuring an effective federal response when appropriate. Finally, we work to create conditions for more effective cyber risk management through efforts to make the cyber ecosystem more fundamentally secure and resilient. This strategy sets forth our goals, objectives, and priorities to successfully execute the
full range of the Secretary of Homeland Security’s cybersecurity responsibilities.
