Planning labels requires setting up a hierarchy of sensitivity levels and a categorization of information on your system. The label_encodings file contains this type of information for your site. You can use one of the label_encodings files that are supplied with Trusted Extensions software. You could also modify one of the supplied files, or create a new label_encodings file that is specific to your site. The file must include the Oracle-specific local extensions, at least the COLOR NAMES section.
Planning labels also involves planning the label configuration. After enabling the Trusted Extensions service, you need to decide if the system must allow logins at multiple labels, or if the system can be configured with one user label only. For example, an LDAP server is a good candidate to have one labeled zone. For local administration of the server, you would create a zone at the minimum label. To administer the system, the administrator logs in as a user, and from the user workspace assumes the appropriate role.
For more information, see Trusted Extensions Label Administration . You can also refer to Compartmented Mode Workstation Labeling: Encodings Format .
When localizing a label_encodings file, international customers must localize the label names only. The administrative label names, ADMIN_HIGH and ADMIN_LOW, must not be localized. All labeled hosts that you contact, from any vendor, must have label names that match the label names in the label_encodings file.
