Title

The Google Android Pie must be configured to disable multi-user modes. (Cat II impact)

Discussion

Multi-user mode allows multiple users to share a mobile device by providing a degree of separation between user data. To date, no mobile device with multi-user mode features meets DoD requirements for access control, data separation, and non-repudiation for user accounts. In addition, the MDFPP does not include design requirements for multi-user account services. Disabling multi-user mode mitigates the risk of not meeting DoD multi-user account security policies.

Check Content

Review documentation on the Google Android device and inspect the configuration on the Google Android device to disable multi-user modes. This validation procedure is performed on both the MDM Administration Console and the Android Pie device. On the MDM console, do the following: 1. Open the restrictions settings. 2. Open user settings. 3. Confirm "Disallow Add User" is selected. On the Android Pie device, do the following: 1. Go to Settings >> System >> Advanced >> Multiple users 2. Ensure that there is no option to add a user. If the MDM console device policy is not set to disable multi-user modes or on the Android Pie device, the device policy is not set to disable multi-user modes, this is a finding.
