Windows Phone 8.1 must be configured to implement the management setting: Employ mobile device management services to centrally manage security-relevant configuration and policy settings.

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. SFR ID: FMT_SMF.1.1 #42

Check Text ( C-59797r1_chk )
This validation procedure is performed on the Windows Phone 8.1 device only. On the Windows Phone mobile device: 1. Go to "settings". 2. Tap on "workplace". 3. Look at the bottom of the screen to see if there is a company/agency name with the small text of "enrolled" under it. If the word "enrolled" is not shown at the bottom of the workplace screen and a button named "add account" is displayed instead, this is a finding.
