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
DHS leverages federal and international partnerships to ensure the necessary tools, resources, and information are available to frontline personnel.
Joint Terrorism Task Force (JTTF): DHS works closely with JTTFs, and the nation’s fusion centers to support terrorism investigations. Currently, DHS personnel are serving at the 104 JTTFs nationwide
Preventing and Combating Serious Crime Agreements (PCSC): DHS, in collaboration with DOJ and the Department of State (DOS), completed PCSC Agreements, or their equivalent with 37 foreign nations to share the biographic and biometric information of suspected terrorists and criminals.
Agreements to Share Information on Lost and Stolen Passports: All 35 Visa Waiver Program (VWP) countries have agreed to share lost and stolen passport information with the United States through INTERPOL or other designated means.
