2.15.1 Audit Notification & Focus Settings


Notification capabilities are designed to allow users to receive updates from applications that are not currently in use. These can be background applications or even notices from processes running on a computer that is not currently being actively used. Where the screen of a computer is visible to others other than the logged-in user due to shared working spaces or public spaces, consideration should be given to the exposure of sensitive data in notifications. Applications that use the system-wide application service may be individually managed, and applications that might expose confidential information to unauthorized users should not expose notifications except to the current user, especially on the locked screen when the computer may be unattended.


Some work environments will handle sensitive or confidential information with applications that can provide notifications to anyone who can see the computer screen. Organizations must review the likelihood that information may be exposed inappropriately and suppress notifications where risk is not organizationally accepted.


Computer users are often juggling too much information through too many applications that want their attention and are often designed to get attention and never let it go. Notifications are a mechanism that can be used to cut through the deluge and allow important issues to be resolved in a timely way. Global controls on limiting user notifications, even for certain applications, could impact productivity and the timely remediation of issues.
