Title

The BlackBerry Device Service server must have the administrative functionality to centrally manage the following security policy rule on managed mobile devices: Enable or disable the USB Port mass storage mode. (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 configuration to determine whether there is administrative functionality to centrally manage the managed mobile device security policy rule to enable or disable the USB Port mass storage mode. If this function is not present, this is a finding. The "Computer Access to Device" rule on the BlackBerry Device Service server specifies whether a computer can access content on a BlackBerry device using a USB connection or the file-sharing option with Wi-Fi. Where BlackBerry Balance is used, The "Computer Access to Work Files" rule applies to the work perimeter only. The "BlackBerry Device Access to USB Device" rule on the BlackBerry Device Service server specifies whether USB devices (for example, USB flash drives and external hard drives) can interact with apps and data on a BlackBerry device. If this rule is set to Disallow, a USB device cannot access data on the BlackBerry device. These Policy rules are applicable for corporate liable devices only, introduced in O.S. version 10.1.0.

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.
