Apple iOS must employ mobile device management services to centrally manage security-relevant configuration and policy settings.

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 mobile device management (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

Note: Not all iOS deployments involve MDM. If the site uses an authorized alternative to MDM for distribution of Configuration Profiles, this check procedure is not applicable. This check procedure is performed on both the iOS management tool and the iOS device. In the iOS management tool, verify the “Serial Number” of the device is listed. Note: The iOS device's serial number can be found on the back of the device on some models and also can be obtained in the Settings App by tapping "General" and then tapping "About". On the iOS device: 1. Open Settings app. 2. Tap "General". 3. Verify "Device Management" or "Profiles & Device Management" is listed. If the iOS device serial number is not listed in the iOS management tool, or if "Device Management" or "Profiles & Device Management" is not listed on the iOS device, this is a finding.
