ℹ️ Check
Verify the EMM system has been configured to either disable access to DOD data, IT systems, and user accounts or wipe managed data and apps if it has detected the iOS/iPadOS 17 BYOAD device has known malicious, blocked, or prohibited managed applications or is configured to access nonapproved third-party applications stores for managed apps. When the Work profile is wiped, all managed data and files in the Files app must be wiped as well. The exact procedure will depend on the EMM system used at the site. If the EMM system has not been configured to either disable access to DOD data, IT systems, and user accounts or wipe managed data and apps if it has detected the iOS/iPadOS 17 BYOAD device has known malicious, blocked, or prohibited managed applications or is configured to access nonapproved third-party applications stores for managed apps, this is a finding.
