About the Homeland Security Advisory System

The Homeland Security Advisory System is designed to target our protective measures when specific information to a specific sector or geographic region is received. It combines threat information with vulnerability assessments and provides communications to public safety officials and the public. Learn more about Home Land Security

Homeland Security Threat Advisories

Homeland Security threat advisories contain actionable information about an incident involving, or a threat targeting, critical national networks or infrastructures or key assets. They could, for example, relay newly developed procedures that, when implemented, would significantly improve security or protection. They could also suggest a change in readiness posture, protective actions, or response. This category includes products formerly named alerts, advisories, and sector notifications. Advisories are targeted to Federal, state, and local governments, private sector organizations, and international partners.

Homeland Security Information Bulletins

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. Such information may include statistical reports, periodic summaries, incident response or reporting guidelines, common vulnerabilities and patches, and configuration standards or tools. It also may include preliminary requests for information. Bulletins are targeted to Federal, state, and local governments, private sector organizations, and international partners.

Color-coded Threat Level System

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. Raising the threat condition has economic, physical, and psychological effects on the nation; so, the Homeland Security Advisory System can place specific geographic regions or industry sectors on a higher alert status than other regions or industries, based on specific threat information.
