Description
Privileged Locations are the primary method Acrobat uses to allow users and admins to specify trusted content that should be exempt from security restrictions, such as when Enhanced Security is enabled. A Privileged Location may be a file, folder, or a host. If the user is allowed to set a Privileged Location, they could bypass security protections.
