The purpose of this legislation, known as the Countering Online Radicalization and Terrorism Act, is to enhance national security by addressing the threats posed by terrorist organizations that use foreign cloud-based messaging applications. The law aims to ensure that the Department of Homeland Security (DHS) regularly assesses these threats and takes necessary actions to mitigate them. Key provisions of the law require the Secretary of Homeland Security to conduct annual assessments of terrorism threats related to the use of foreign messaging applications.
