Department of Homeland Security

The Department of Homeland Security (DHS) has a vital mission: to secure the nation and protect the American People from harm. This requires the dedication of more than 240,000 employees in jobs that range from aviation and border security to emergency response, from cybersecurity analyst to chemical facility inspector.

Key Components

Homeland security information sharing architecture is comprised of four key components:

  • National Network of Fusion Centers are focal points within the state and local environment for receipt, analysis, gathering, and sharing of threat-related information by collaborating with  federal, state, local, tribal, territorial (SLTT) and private sector partners.
  • Nationwide Suspicious Activity Reporting Initiative (SAR) is a unified process for reporting, tracking, and accessing information while protecting the privacy and civil liberties of Americans, as required by the National Strategy for Information Sharing.
  • National Terrorism Advisory System (NTAS) communicates terror-related threat information to the public, government agencies, first responders, transportation hubs, and the private sector, replacing the earlier, color-coded Homeland Security Advisory System (HSAS).
  • If You See Something, Say Something is DHS’s nation-wide public awareness campaign emphasizing the importance of reporting suspicious activity to law enforcement. 

Federal and International Partnerships
