Label Encodings File

All label components for a system, that is, classifications, compartments, and the associated rules, are stored in an ADMIN_HIGH file, the label_encodings file. This file is 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 regular users

• Printing specifications – Identification and handling information for print banners, trailers, headers, footers, and other security features on printer output

• Customizations – Local definitions including label color codes, and other defaults

For more information, see the label_encodings(4) man page. Detailed information can also be found in Solaris Trusted Extensions Label Administration and Compartmented Mode Workstation Labeling: Encodings Format.
