D.1 The National Terrorism Advisory System (NTAS) replaces the color-coded Homeland Security Advisory System (HSAS). This new system will more effectively communicate information about terrorist threats by providing timely, detailed information to the public, Government agencies, first responders, airports and other transportation hubs, and the private sector.
D.2 NTAS alerts are based on the nature of the threat. In some cases, alerts are sent directly to law enforcement or affected areas of the private sector, while in others, alerts are issued more broadly to the American people through both official and media channels.
D.3 NTAS alerts contain a sunset provision indicating a specific date when the alert expires; there will not be a constant NTAS alert or blanket warning that there is an overarching threat. If threat information changes for an alert, the Secretary of Homeland Security may announce an updated NTAS alert. All changes, including the announcement that cancels an NTAS alert, will be distributed the same way as the original alert.

b. The program shall include security measures such as ID checks for entry, enforcing NASA policy on the wearing and display of the NASA photo-ID badge, random vehicle inspections, consistent and current mandatory security training, exercising emergency response capability; to include response to increase in threat condition, periodic security assessments of individual Centers and facilities to ensure all reasonable measures are taken to mitigate vulnerabilities.
