Content Protection Strength IT policy rule

Description

This rule specifies the cryptography strength that a BlackBerry® device uses to encrypt content that it receives while it is locked. When you specify a value, the content protection feature is turned on.

Default values

The default value in the Advanced security and Advanced Security with No 3rd Party Applications IT policies is Strong.

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

Usage

Configure this rule to Strong to use a 160-bit ECC public key. This key provides good security and good performance and is adequate for most situations.

Configure this rule to Stronger to use a 283-bit ECC public key. This key provides better security but slower performance than the Strong setting.

Configure this rule to Strongest to use a 571-bit ECC public key. This key provides the highest level of security but the slowest performance of the three settings.

For BlackBerry devices that are running BlackBerry® Device Software version 5.0 and later, if onboard device memory exists on the BlackBerry device when you configure this rule, the rule also encrypts the onboard device memory (embedded M.C.) to the user password and a device-generated key.

To encrypt the media files in the onboard device memory, configure the Force Encryption on Internal File System Media Files IT policy rule, or instruct the BlackBerry device user to configure file encryption.

For BlackBerry devices that are running BlackBerry Device Software versions that are earlier than version 5.0, you can configure the External File System Encryption Level IT policy rule. The External File System Encryption Level IT policy rule also encrypts the media card.

Dependencies

A BlackBerry device uses this rule only if you configure the Password Required IT policy rule to Yes.

If you configure this rule to Strong or Stronger, configure the Minimum Password Length IT policy rule to 12 characters. If you configure the content protection strength to Strongest, instruct the user to create a password of at least 21 characters. These password lengths maximize the encryption strength that the longer ECC keys are designed to provide.

Minimum requirements

  • Java® based BlackBerry device
  • BlackBerry® Application Suite version 1.0
  • BlackBerry® Connect™ version 4.0
  • BlackBerry® Device Software version 4.0
  • BlackBerry® Enterprise Server version 4.0
