The BlackBerry Device Service server must enable Bluetooth 128-bit encryption via centrally managed policy.

Overview

Description
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 Text ( C-46447r2_chk )
Review the BlackBerry Device Service server configuration to determine whether Bluetooth 128-bit encryption is enabled. If there are multiple policies, they must all be reviewed. The "Minimum Bluetooth Encryption Key Length" rule on the BlackBerry Device Service server specifies the minimum encryption key length that a BlackBerry device uses to encrypt Bluetooth connections. 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 "Minimum Bluetooth Encryption Key Length" is set to "16 Bytes". Otherwise, this is a finding. Note: Check text is applicable for devices with EMM-Regulated (Work Space only).
