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. Emails are only visible in an email reader at the label of the message. The label of an email is printed when the email is printed.
