|Oracle Solaris Trusted Extensions Administrator's Procedures Oracle Solaris 10 8/11 Information Library|
Settings in the label_encodings and the policy.conf files together define default security attributes for user accounts. The values that you explicitly set for a user override these system values. Some values that are set in these files also apply to role accounts. For security attributes that you can explicitly set, see Configurable User Attributes in Trusted Extensions.
The label_encodings file defines a user's minimum label, clearance, and default label view. For details about the file, see the label_encodings(4) man page. Your site's label_encodings file was installed by your initial setup team. Their decisions were based on Devising a Label Strategy in Oracle Solaris Trusted Extensions Configuration Guide, and examples from Oracle Solaris Trusted Extensions Label Administration.
Label values that the security administrator explicitly sets for individual users in the Solaris Management Console are derived from the label_encodings file. Explicitly set values override the values in the label_encodings file.
The Oracle Solaris /etc/security/policy.conf file contains the default security settings for the system. Trusted Extensions adds two keywords to this file. You can add these keyword=value pairs to the file if you want to change the system-wide value. These keywords are enforced by Trusted Extensions. The following table shows the possible values for these security settings and their default values.

The authorizations and rights profiles that are defined in the policy.conf file are in addition to any authorizations and profiles that are assigned to individual accounts. For the other fields, the individual user's value overrides the system value.
Planning User Security in Trusted Extensions in Oracle Solaris Trusted Extensions Configuration Guide includes a table of every policy.conf keyword. See also the policy.conf(4) man page.
