A tool to combat terrorism. Threat Conditions characterize the risk of terrorist attack. Protective Measures are the steps that will be taken by government and the private sector to reduce vulnerabilities. The HSAS establishes five Threat Conditions with associated suggested Protective Measures:
Low Condition
Green
Low risk of terrorist attacks. The following Protective Measures may be applied:
Refining and exercising preplanned Protective Measures
Ensuring personnel receive training on HSAS, departmental, or agency-specific Protective Measures; and
Regularly assessing facilities for vulnerabilities and taking measures to reduce them.
Guarded Condition

Providing the public with necessary information.
Elevated Condition

Significant risk of terrorist attacks. In addition to the previously outlined Protective Measures, the following may be applied:
Increasing surveillance of critical locations;
Coordinating emergency plans with nearby jurisdictions;
Assessing further refinement of Protective Measures within the context of the current threat information; and
Implementing, as appropriate, contingency and emergency response plans.

Coordinating necessary security efforts with armed forces or law enforcement agencies;
Taking additional precaution at public events;
Preparing to work at an alternate site or with a dispersed workforce; and Restricting access to essential personnel only.
