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

Overview

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.

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 Over-the-Air management tool and the iOS device. In the iOS Over-the-Air management tool, verify the “Serial Number” of the device is listed. For example, in Mobile Iron Admin Portal: 1. Ask the MDM administrator to display the "USERS & DEVICES". 2. Click or tap on the word "Devices". 3. Click or tap the user. 4. Click or tap the “Details" disclosure triangle under "Device Details”. 5. Verify the “SerialNumber" listed in “Details” matches the serial number of the enrolled device. Note: The iOS device's serial number can be found on the back of the device on some models, and also is obtained in the Settings App by tapping "General" and then tapping "About". On the iOS device: 1. Open Settings app. 2. Tap "General". 3. Tap "Profiles". 4. Verify the management profile from the iOS Over-the-Air management tool is present. If the iOS device serial number is not listed in the iOS Over-the-Air management tool or the management profile from the iOS Over-the-Air management tool is not present on the iOS device, this is a finding.

Fix Text (F-48797r2_fix)
Implement MDM to centrally manage configuration settings. Enroll the iOS device into MDM per the MDM vendor’s instructions. For example, download the Mobile Iron app onto the iOS device. Launch the app, and go through enrollment prompts to enroll the device into the Mobile Iron MDM.
