About the Homeland Security Advisory System

The Homeland Security Advisory System is designed to guide our protective measures when specific information to a particular sector or geographic region is received. It combines threat information with vulnerability assessments and provides communications to public safety officials and the public.
- Homeland Security Threat Advisories contain actionable information about an incident involving, or a threat targeting, critical national networks or infrastructures or key assets.
- Homeland Security Information Bulletins communicate information of interest to the nation’s critical infrastructures that do not meet the timeliness, specificity, or significance thresholds of warning messages.
- Color-coded Threat Level System is used to communicate with public safety officials and the public at-large through a threat-based, color-coded system so that protective measures can be implemented to reduce the likelihood or impact of an attack.
This system was established in Homeland Security Presidential Directive 3.
