Description
MailDrop allows users to send large attachments (up to 5GB) 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.1.1 #47

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-278792r1150866_chk)

Review configuration settings to confirm "Allow MailDrop" is disabled. This validation procedure is performed on both the Apple iOS/iPadOS management tool and the iPhone and iPad. 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/iPadOS management tool, verify "Allow MailDrop" is not checked. On the iPhone and iPad: 1. Open the Settings app. 2. Tap "General". 3. Tap "VPN & Device Management". 4. Tap the Configuration Profile from the Apple iOS/iPadOS management tool containing the restrictions policy. 5. Tap "Mail". 6. Tap the mail account. 7. Verify "Mail Drop Enabled" is set to "No". If "Allow MailDrop" is not disabled in the Apple iOS/iPadOS management tool or the restrictions policy on the iPhone and iPad lists "Mail Drop Enabled" as "Yes", this is a finding.

Fix Text (F-83231r1150622_fix)

Configure the Apple iOS/iPadOS configuration profile to disable "Allow MailDrop".
