Per-Message Security
Access labels allow you to prevent a Broker client from receiving a specific document regardless of whether its client group is authorized to receive the document type to which the message belongs. The publisher labels a document's access rights, and Broker enforces access at the per-message level.
Access labels also allow you to provide a receiving Broker client with information about the publisher's rights.
