A federal court ruled on Tuesday that the Department of Homeland Security has 30 days to disclose its plans for an “Internet kill switch,” The Washington Free Beacon reports.

In order to prevent terrorists from using cell phones to remotely detonate bombs, DHS developed secret protocols, called Standard Operating Procedure 303, to govern how the agency would direct the shutdown of wireless networks in the event of an emergency.

The Electronic Privacy Information Center (EPIC) has been battling the agency since July 2012 to release the protocols — considered “Internet kill switch” — to the public.
