Title

Apple iOS must implement the management setting: disable Airdrop. (Cat II impact)

Discussion

An Airdrop feature is a way to send contact information or photos to other users with this same feature enabled. This feature enables a possible attack vector for adversaries to exploit. Once the attacker has gained access to the information broadcast by this feature, he/she may distribute this sensitive information very quickly and without DoD’s control or awareness. By disabling this feature, the risk of mass data exfiltration will be mitigated. 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 #45

Check Content

Note: This requirement is not applicable to Apple iOS devices that do not support AirDrop, which include iPhones prior to iPhone 5 and iPads prior to iPad 3rd generation. Review configuration settings to confirm “AirDrop” 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, then 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 "Treat Airdrop as unmanaged destination" is checked. On the Apple iOS device: Part 1. 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles" or "Profiles & Device Management" or "Device Management". 4. Tap the Configuration management tool containing the restrictions policy. 5. Tap "Restrictions". 6. Verify "Sharing managed documents using AirDrop not allowed" is listed. Part2. 1. Access Control Center by swiping up from the bottom of the device on the home screen. 2. Verify "AirDrop" is displayed with no other text in this box, or verify "AirDrop" does not appear at all. If "Treat Airdrop as unmanaged destination" is disabled in the Apple iOS management tool, the restrictions policy on the Apple iOS device from the Apple iOS management tool does not list "Sharing managed documents using AirDrop not allowed", or if AirDrop appears in the Control Center followed by "Contacts Only" or "Everyone", this is a finding. Note: If the site has implemented Device Enrollment Program (DEP) (not required), AirDrop can be managed via the MDM (supervised mode).
