After reviewing the current threat environment, the Department of Homeland Security last week reissued its National Terrorism Advisory System Bulletin. According to the department, foreign terrorist organizations continue to exploit the internet to inspire, enable and direct individuals in the U.S. to commit terrorist acts. The department encourages those who observe suspicious activity to report it to law enforcement and to be prepared for security threats. This bulletin was first issued in 2015 and has since been reissued six times.
