Label Ranges Restrict Access

Label ranges set limits on the following:

• The labels at which hosts can send and receive information.

• The labels at which processes acting on behalf of users and roles can access files and directories in zones.

• The labels at which users can allocate devices, thereby restricting the labels at which files can be written to storage media in these devices.

• The labels at which users can send jobs to printers.

• The labels at which users can log in to workstations. In addition to the user's label range, a label range on the frame buffer can be used to restrict access to a system.

Labels are automatically assigned to email messages, and the labels then show on printed emails.
