Description
If the user is able to add a personal email account (POP3, IMAP, EAS) to the work email app, it could be used to forward sensitive DOD data to unauthorized recipients. Restricting email account addition to the administrator or restricting email account addition to allow listed accounts mitigates this vulnerability. SFRID: FMT_SMF.1.1 #47

ℹ️ Check
Review the managed Google Android 15 work profile configuration settings to confirm that users are prevented from adding personal email accounts to the work email app. This procedure is performed on both the EMM Administrator console and the managed Google Android 15 device. COPE: On the EMM console: 1. Open "Set user restrictions". 2. Verify "Disallow modify accounts" is toggled to "ON". On the managed Google Android 15 device: 1. Open Settings. 2. Tap "Passwords & accounts". 3. Select "Work". 4. Tap "Add account". 5. Verify a message is displayed to the user stating, "Action not allowed". If on the EMM console the restriction to "Disallow modify accounts" is not set, or on the managed Android 15 device the user is able to add an account in the Work section, this is a finding.
