Title

The BlackBerry Device Service server must disallow Personal Space applications access to the Work Space network connection 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.

Check Content

Review the BlackBerry Device Service server policy configuration to determine whether Personal Space applications access to the Work Space network connection has been disallowed. If there are multiple policies, they must all be reviewed. Otherwise, this is a finding.

Fix Text

Configure the centrally managed BlackBerry Device Service server policy rule to disallow Personal Space applications access to the Work Space network connection. 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 "Work Network Usage for Personal Apps" is set to "Disallow". Note: Check text is applicable for EMM-Corporate (BlackBerry Balance) devices only. This requirement is N/A for EMM-Regulated (Work Space only) devices.
