“Department of Defense leaders have disabled a secure file sharing system due to security risks and have not set a date to reinstate the technology. The Army Aviation and Missile Research Development and Engineering Center Safe Access File Exchange, or AMRDEC SAFE site was disabled as a preventative measure after outside agencies identified potential security risks, a statement from AMRDEC to Fifth Domain said. The statement also said it is uncertain if the site will be reinstated, although DoD officials are not aware of any other government-run secure file transfer sites. The tool was created as an alternate to the traditional File Transfer Protocol or email, and operates much like the popular commercial file-sharing system Dropbox. “
