Title
Apple iOS must implement the management setting: not have any Family Members in Family Sharing. (Cat III impact)
Discussion
Apple's Family Sharing service allows Apple iOS users to create a Family Group whose members have several shared capabilities, including the ability to lock, wipe, play a sound on, or locate the Apple iOS devices of other members. Each member of the group must be invited to the group and accept that invitation. A DoD user's Apple iOS device may be inadvertently or maliciously wiped by another member of the Family Group. This poses a risk that the user could be without a mobile device for a period of time or lose sensitive information that has not been backed up to other storage media. Configuring Apple iOS devices so their associated Apple IDs are not members of Family Groups mitigates this risk. Note: If the site uses Apple's optional Device Enrollment Program (DEP), this control is available as a supervised MDM control. SFR ID: FMT_SMF_EXT.1.1 #47
Check Content
Review configuration settings to confirm Family Sharing is disabled. Note that this is a User based Enforcement (UBE) control, which cannot be managed by an MDM server. This check procedure is performed on the Apple iOS device. On the Apple iOS device: 1. Open the Settings app. 2. At the top of the screen, if "Sign in to your iPhone" is listed, this requirement has been met. 3. If the user profile is signed into iCloud, tap the user name 4. Tap "Family Sharing" 5. Verify no accounts are listed other than the "Organizer" Note: The Apple iOS device must be connected to the Internet to conduct this validation procedure. Otherwise, the device will display the notice "Family information is not available", in which case it cannot be determined if the configuration is compliant. If accounts (names or email addresses) are listed under "FAMILY MEMBERS" on the Apple iOS device, this is a finding. Note: If the site has implemented DEP (not required), this setting can be managed via the MDM (supervised mode).
Fix Text
The user must either remove all members from the Family Group on the Apple iOS device or associate the device with an Apple ID that is not a member of a Family Group.
