Report: Military bans disks, removable media

The Pentagon is telling troops to stop using CDs, DVDs, thumb drives and all other forms of removable media or risk facing a court-martial, according to a report from Wired.

According to the report, Maj. Gen. Richard Webber, commander of Air Force Network Operations issued a "Cyber Control Order" on Dec. 3 instructing airmen to immediately stop using removable media on the Defense Department's secret network. The other branches of the military have reportedly received similar directives.

The order is a response to the leaking of thousands of classified diplomatic cables and documents to the whistleblower site WikiLeaks, which has come under international scrutiny for publishing the names of military and intelligence informants.

Army Pfc. Bradley Manning, who was arrested in May and charged in connection with the leaks, allegedly downloaded classified materials to a CD disguised as a Lady Gaga album.

The military has previously flirted with banning thumb drives and other forms of removable media for cybersecurity reasons: the devices could contain worms or viruses aimed at disabling networks or stealing classified information.

U.S. lawmakers have also introduced legislation in both houses of Congress that would make it illegal to disclose the names of classified military or intelligence informants.
