The Homeland Security Advisory System is a system for measuring and communicating the terrorist threat level in the U.S.
A color-coded Threat Level System is used to communicate the threat level to the public so that protective measures can be implemented to reduce the likelihood or impact of an attack. The higher the Threat Condition, the greater the risk of a terrorist attack. Risk includes both the probability of an attack occurring and its potential seriousness.
The terrorist threat level is elevated when specific information about a threat to a particular sector or geographic region is received. Threat Conditions may be assigned for the entire Nation, or they may be set for a particular geographic area or industrial sector.
