Assessment Title

Rule Text

The system must be configured to prevent the display of error messages to the user.

Description

Discussion Text

Displaying error messages to users provides them the option of sending the reports. Error reports should be sent silently, unknown to the user. This setting controls whether users are shown an error dialog box that lets them report an error.
