GOOG-17-005800 - Google Android 17 must be configured to not display the following (work profile) notifications when the device is locked: [selection:

Information

- Email notifications
 - Calendar appointments
 - Contact associated with phone call notifications
 - Text message notifications
 - Other application-based notifications
 - All notifications] - work profile notifications when the device is locked: [selection:

Many mobile devices display notifications on the lock screen so that users can obtain relevant information in a timely manner without having to frequently unlock the phone to determine if there are new notifications. However, in many cases, these notifications can contain sensitive information. When they are available on the lock screen, an adversary can see them merely by being in close physical proximity to the device. Configuring the mobile operating system to not send notifications to the lock screen mitigates this risk.

The requirement statement specifies the DoW-mandated configuration of this MDFPP element. The STIG author must select 'all notifications' if there is no other means to administratively restrict applications from issuing notifications in the locked state where those notifications could include DoW sensitive information.
