Title

Apple iOS must implement the management setting: Disable Allow MailDrop. (Cat II impact)

Discussion

MailDrop allows users to send large attachments in up to 5GB in size via iCloud. Storing data with a non-DoD cloud provider may leave the data vulnerable to breach. Disabling non-DoD cloud services mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #45

Check Content

Review configuration settings to confirm "Allow MailDrop” is disabled. This validation 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 "Allow MailDrop" is not checked. 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 "Accounts". 6. Tap the mail account. 7. Verify "Mail Drop Enabled" is "No". If "Allow MailDrop" is not disabled in the Apple iOS management tool or the restrictions policy on the Apple iOS device from the Apple iOS management tool lists "Mail Drop Enabled" as "Yes", this is a finding.

Fix Text

Configure the Apple iOS configuration profile to disable Allow MailDrop.
