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.

Default values

The default value in the Default IT policy is Not required.

The default value in the Advanced Security and Advanced Security (disallow application downloads) IT policies is Encrypt to User Password (excluding multimedia directories).

The default value in all other preconfigured IT policies is a null value.

Usage

You can use this rule to require that a BlackBerry device encrypt 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 BlackBerry device is designed to use the master keys to decrypt and encrypt files on the media card. A BlackBerry device is designed to use the BlackBerry device key, a user-provided password, or both to encrypt the master keys.

Change this rule to Encrypt to User Password (excluding multimedia directories) if the media card requires encryption with a password that the user provides.

Change this rule to Encrypt to User Password (including multimedia directories) if the media card requires encryption with a password that the user provides.

Change this rule to Encrypt to Device Key (excluding multimedia directories) if the media card requires encryption with a BlackBerry device key.

Change this rule to Encrypt to Device Key (including multimedia directories) if the media card requires encryption with a BlackBerry device key.

Change this rule to Encrypt to User Password and Device Key (excluding multimedia directories) if the media card requires encryption with a password that the user provides and a BlackBerry device key.

Change this rule to Encrypt to User Password and Device Key (including multimedia directories) if the media card requires encryption with a password that the user provides and the BlackBerry device key.
