The BlackBerry Device Service server must have the administrative functionality to centrally manage the following security policy rule on managed mobile devices: Disallow mobile device applications the ability to reset the device lock timer.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

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.

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 disallow mobile device applications the ability to reset the device lock timer. If this function is not present, this is a finding. The "Application Security Timer Reset" rule on the BlackBerry Device Service server specifies whether apps can reset the security timer on a BlackBerry device to prevent the device from locking after either, 1) the period of user inactivity that you specify in the Security Timeout rule, or 2) the user specifies in the Password Lock settings on the device elapses. If this rule is set to disallow, the device will lock without user interaction when running apps that attempt to reset the security timer, such as apps that display navigation information, slideshows, and videos. IT policy rules can be specified per group or per user. To add an IT policy to a group: 1. In the BlackBerry Administration Service, on the BlackBerry solution management menu, expand Group. 2. 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. For more details and information, please see the "Setting up device controls" section of the BlackBerry Enterprise Service 10 BlackBerry Device Service, Version: 6.2 Administration Guide.
