Title
Samsung Android's Work profile must be configured to prevent users from adding personal email accounts to the work email app.
Control
Review the configuration to determine if the Samsung Android devices are preventing users from adding personal email accounts to the work email app. On the management tool, in the device restrictions section, verify "Modify accounts" is set to "Disallow". COPE: On the Samsung Android device: 1. Open Settings >> Accounts and backup >> Manage accounts. 2. Navigate to the "Work" tab. 3. Verify no account can be added. COBO: On the Samsung Android device: 1. Open Settings >> Accounts and backup >> Manage accounts. 2. Verify no account can be added. If on the management tool "Modify accounts" is not set to "Disallow", or on the Samsung Android device an account can be added, this is a finding.
Discussion
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 DoW data to unauthorized recipients. Restricting email account addition to the Administrator or to allow-listed accounts mitigates this vulnerability. SFR ID: FMT_MOF_EXT.1.2 #47
