National Terrorism Advisory System (NTAS) check current status

The world has changed since September 11, 2001. We remain a nation at risk from terrorist attacks and will remain at risk for the foreseeable future. We must remain vigilant, prepared, and ready to deter terrorist attacks.

In April of 2011, the United States Department of Homeland Security developed a new National Terrorism Advisory System (NTAS) to replace the older color-coded Homeland Security Advisory System (HSAS).
