Ensure 'Disable all Trust Bar notifications for security issues' is set to 'Disabled'

HochStufe 1Automatisiertoffice

Beschreibung

This policy setting controls whether Office applications notify users when potentially unsafe features or content are detected, or whether such features or content are silently disabled without notification. The recommended state for this setting is: Disabled. Rationale: The Message Bar in Office applications is used to identify security issues, such as unsigned macros or potentially unsafe add-ins. When such issues are detected, the application disables the unsafe feature or content and displays the Message Bar at the top of the active window. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\common\trustcenter:trustbar (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 0. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
