Title
Apple iOS must implement the management setting: not allow use of Handoff. (Cat III impact)
Discussion
Handoff permits a user of an Apple iOS device to transition user activities from one device to another. Handoff passes sufficient information between the devices to describe the activity, but app data synchronization associated with the activity is handled though iCloud, which should be disabled on a compliant Apple iOS device. If a user associates both DoD and personal devices to the same Apple ID, the user may improperly reveal information about the nature of the user's activities on an unprotected device. Disabling Handoff mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #45
Check Content
Review configuration settings to confirm "Allow Handoff" is disabled. This check procedure is performed on both the Apple iOS management tool and the Apple iOS device. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the Apple iOS management tool, verify "Allow Handoff" is unchecked. Alternatively, verify the text "<key>allowActivityContinuation</key> <false/>" appears in the configuration profile (.mobileconfig file). On the Apple iOS device: 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles" or "Profiles & Device Management" or "Device Management". 4. Tap the Configuration Profile from the Apple iOS management tool containing the restrictions policy. 5. Tap "Restrictions". 6. Verify "Handoff not allowed" is listed. If "Allow Handoff" is checked in the Apple iOS management tool, "<key>allowActivityContinuation</key> <true/>" appears in the configuration profile, or the restrictions policy on the Apple iOS device from the Apple iOS management tool does not list "Handoff not allowed", this is a finding.
Fix Text
Install a configuration profile to disable continuation of activities among devices and workstations.
