Deleting all device data from the BlackBerry device memory
- all user data
- any references to your organization’s PIN encryption key
- any references to the device transport key
- if applicable, authentication information (for example, the binding information of the smart card)
- IT policy public key
- if you are resetting the BlackBerry device to the factory default settings, any references to past hashes of the BlackBerry device password
- record of time elapsed since the BlackBerry device was last turned on
- if you are resetting the BlackBerry device to the factory default settings, stored IT policy
- If specified, all third-party applications and application data
If you or a user turns on content protection, the BlackBerry device uses a memory-scrubbing process to overwrite the flash memory on the BlackBerry device and the on-board BlackBerry device memory. The memory-scrubbing process complies with United States government requirements for deleting sensitive user data, including US Department of Defense Directive 5220.22-M and NIST Special Publication 800-88.
For BlackBerry® Device Software versions 5.0 and later, if you configure the Media Card Format on Device Wipe IT policy rule the BlackBerry device can also delete all user data from a media card. By default, the user can choose to delete third-party applications and the user data on the media card when the user permanently deletes all deivce data.
