Label Encodings Files

All label components for a system--that is, classifications, compartments, and the associated rules--are stored in a file called label_encodings(4), located in the /etc/security/tsol directory. The security administrator sets up the label_encodings file for the site. A label encodings file contains:

• Component definitions - Definitions of classifications, compartments, labels, and clearances, including rules for required combinations and constraints

• Accreditation range definitions - Specification of the clearances and minimum labels that define the sets of available labels for the entire system and for normal (non-administrative) users

• Printing specifications - Identification and handling information for print banners, trailers, headings, footers, and other security features for printouts

• Customizations - Local definitions including label color codes, alternative names for classifications, compartments, and markings in the graphical interface, and other items

For more information on the label_encodings file, see the man page for label_encodings(4) and the guides Trusted Solaris Label Administration and Compartmented Mode Workstation Labeling: Encodings Format.
