The Add-In Trust Level must be configured.
An XCCDF Rule
Description
Under normal circumstances the installed COM add-ins are applications that have been approved and intentionally deployed by the organization and therefore they should not pose a security threat. However, if malware has infected systems it is possible that the malware will use the COM add-in feature to perform unauthorized actions. This setting enforces the default configuration, and therefore is unlikely to cause significant usability issues for most users.
