National Terrorism Alert System

The new National Terrorism Advisory System (NTAS) provides the means to share heightened terrorism threat information across our nation and allow authorities and stakeholders to take protective action. This new system is in addition to the normal flow of threat information provided to the American people and key sector stakeholders on a regular basis.

The attache file is an interim stakeholder information handbook for NTAS, and is intended to provide the basic necessary information about the system and to spotlight key points where stakeholders are involved both in the decision processes and execution activities. The interim handbook is just a first step towards joint development of a more comprehensive NTAS stakeholder doctrine. DHS will coordinate refinement and content of this handbook as a joint effort in the future with all stakeholders.
