What is the purpose of the National Terrorism Advisory System (NTAS)?

The National Terrorism Advisory System (NTAS) is designed to provide information to the public about potential threats related to terrorism. Its primary goal is to communicate details about current threats and alerts, helping citizens be informed about the nature of the risk and any actions they may need to consider in response. This system plays a crucial role in national security by ensuring that the public has access to timely and reliable information regarding terrorism threats, which can enhance community preparedness and vigilance.

The other options do not align with the core purpose of NTAS. For instance, preventing international fraud focuses on financial crimes rather than terrorism threats, while classifying immigration applications and regulating visa issuance pertain to immigration processes rather than directly addressing terrorism concerns.
