The BlackBerry Device Service server must disable the Hands-Free Profile (HFP) Bluetooth profile via centrally managed policy.
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.
Review the BlackBerry Device Service server policy configuration to determine whether the Hands-Free Profile (HFP) Bluetooth profile has been disabled. If there are multiple policies, they must all be reviewed. 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 > > View complete IT Policy > Hardware" and verify both "Transfer Work Contacts Using Bluetooth PBAP or HFP" and "Bluetooth HFP" are set to "Disallow".
