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. 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 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
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.
