Information

Zone information must be preserved when saving attachments.

GROUP ID: V-220955RULE ID: SV-220955r991589

Preserving zone of origin (internet, intranet, local, restricted) information on file attachments allows Windows to determine risk.

Solution

The default behavior is for Windows to mark file attachments with their zone information.

If this needs to be corrected, configure the policy value for User Configuration >> Administrative Templates >> Windows Components >> Attachment Manager >> 'Do not preserve zone information in file attachments' to 'Not Configured' or 'Disabled'.
