SV-86507r1_rule Apple iOS must wipe protected or sensitive data upon unenrollment from MDM.

Vulnerability discussion

When a mobile device is no longer going to be managed by MDM technologies, its protected/sensitive data must be sanitized because it will no longer be protected by the MDM software, so it is at much greater risk of unauthorized access and disclosure.SFR ID: FMT_SMF_EXT.2.1

Check content

Note: The procedure below is exactly the same for requirement AIOS-10-080102. This procedure needs to be performed only once. Note: Not all Apple iOS deployments involve MDM. If the site uses an authorized alternative to MDM for distribution of configuration profiles, this check procedure is not applicable. This check procedure is performed on the Apple iOS management tool. In the Apple iOS management tool, for each managed app, verify the app is configured to be removed when the MDM profile is removed. If one or more managed apps are not set to be removed upon device MDM unenrollment, this is a finding.

Fix text

Install a configuration profile to delete all managed apps upon device unenrollment.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
