The BlackBerry Device Service server must disallow mobile device applications the ability to reset the Work Space lock timer via centrally managed policy.

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 policy configuration to determine whether the mobile device applications' ability to reset the device lock timer has been disabled. If there are multiple policies, they must all be reviewed. 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 is specified in the Security Timeout rule elapses, or 2) the period of inactivity that 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. 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 > Security" and verify "Application Security Timer Reset" is set to "Disallow". Otherwise, this is a finding.
