Title

The BlackBerry Device Service server must force the display of a warning banner on the lock screen of the mobile device via centrally managed policy. (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. The warning banner must be displayed before or immediately after the user successfully unlocks the mobile device or unlocks a secure application where sensitive DoD data is stored: "I've read consent to terms in IS user agreem't." (Wording must be exactly as specified.)

Check Content

Review the BlackBerry Device Service server policy configuration to determine whether the Owner Information has been set. Otherwise, this is a finding.

Log into BlackBerry Administration Service, and under "BlackBerry solution management" on the left side of the screen, navigate to "Policy > Manage IT policies > <Policy Name> > View complete IT Policy > Security" and verify "Owner Information" is set to "I've read & consent to terms in IS user agreem't".
