Title

The BlackBerry Device Service server must have the administrative functionality to centrally manage the following security policy rule on managed mobile devices: Perform a "Data Wipe" function whereby all data stored in user addressable memory on the mobile device and the removable memory card is erased when the maximum number of incorrect passwords for device unlock has been reached. (Cat II impact)

Discussion

Security related parameters are those parameters impacting the security state of the system and include parameters related to the implementation of other IA controls. If these controls are not implemented, the system may be vulnerable to a variety of attacks. The use of an MDM allows an organization to assign values to security related parameters across all the devices it manages. This provides assurance that the required mobile OS security controls are being enforced, and that the device user or an adversary has not modified or disabled the controls. It also greatly increases efficiency and manageability of devices in a large scale environment relative to an environment in which each device must be configured separately. Data wipe could be accomplished by deleting the data-at-rest encryption key (data obfuscation).

Review the BlackBerry Device Service server configuration to determine whether there is administrative functionality to centrally manage the managed mobile device security policy rule to perform a "Data Wipe" function whereby all data stored in user addressable memory on the mobile device and the removable memory card is erased when the maximum number of incorrect passwords for device unlock has been reached. If this function is not configured, this is a finding. The "Maximum Password Attempt" rule allows administrator to enforce data wipe upon maximum number of incorrect passwords. IT policy rules can be specified per group or per user. To add an IT policy to a group: 1. In the BlackBerry Administration Service, on the BlackBerry solution management menu, expand Group. 2. Click Manage groups. 3. Click the name of the group. 4. Click Edit group. 5. Click the Policies tab. 6. In the IT policy list, select the IT policy. 7. Click Save all. To add an IT policy to a user account: 1. In the BlackBerry Administration Service, on the BlackBerry solution management menu, expand User. 2. Click Manage users. 3. Search for a user account. 4. In the search results, select the check box for the user account. 5. In the Add to user configuration list, click Set IT policy. 6. In the IT policy drop-down list, select the IT policy. 7. Click Save.
