The Department of Homeland Security was formed in the wake of the terrorist attacks of September 11, 2001, as part of a determined national effort to safeguard the United States against terrorism. The Department became the third-largest Federal department, bringing together 22 different Federal agencies, each with a role in this effort.

We have taken significant steps to create a unified and integrated Department that will enhance our performance by focusing on:

• accountability
• efficiency
• transparency, and
• leadership development
