The purpose of this legislation is to improve and modernize the National Terrorism Advisory System (NTAS), which is a system used by the U.S. government to communicate information about potential terrorism threats to the public and relevant authorities. The goal is to ensure that this system is more effective in providing timely and useful information regarding threats to safety. Key provisions of the legislation require the Secretary of Homeland Security to create a strategy for modernizing the NTAS within one year of the law being enacted.
