External File System Encryption Level IT policy rule

Description

This rule specifies the level of encryption that a BlackBerry® device uses to encrypt files that it stores on a media card. You can use this rule to require that the device encrypts a media card, either including or excluding media-card files. You cannot use this rule to encrypt files that a BlackBerry device user transfers to the media card manually (for example, from a USB mass storage device).

The master keys for the media card are stored on the media card. A device is designed to use the master keys to decrypt and encrypt files on the media card. A device is designed to use the device key, a user-provided password, or both to encrypt the master keys.
