From the overview: " The DHS FY14-18 Strategic Plan focuses on how we will implement the goals laid out in the 2014 Quadrennial Homeland Security Review. It describes the missions and goals of homeland security, the strategies we use to achieve those goals, and the ways in which we measure our success. It also sets several key, priority efforts under each mission and describes how those priorities will be achieved through the DHS Unity of Effort Initiative. The Homeland Security vision is a homeland that is safe, secure, and resilient against terrorism and other hazards, where American interests, aspirations, and way of life can thrive. This requires the dedication of more than 240,000 employees in jobs that range from aviation and border security to emergency response, from cybersecurity analysis to chemical facility inspections. Our duties are wide-ranging, but our goal is clear -- keeping America safe. The 2014 Quadrennial Homeland Security Review reaffirmed the five-mission structure of DHS: (1) Prevent Terrorism and Enhance Security (2) Secure and Manage our Borders (3) Enforce and Administer Our Immigration Laws (4) Safeguard and Secure Cyberspace; and (5) Strengthen National Preparedness and Resilience."
