Oracle Solaris auditing is described in Chapter 28, Oracle Solaris Auditing (Overview), in System Administration Guide: Security Services. For zones considerations associated with auditing, see the following sections:
An audit record describes an event, such as logging in to a system or writing to a file. The record is composed of tokens, which are sets of audit data. By using the zonename token, you can configure Oracle Solaris auditing to identify audit events by zone. Use of the zonename token allows you to produce the following information:
Audit records that are marked with the name of the zone that generated the record
An audit log for a specific zone that the global administrator can make available to the zone administrator
Oracle Solaris audit trails are configured in the global zone. Audit policy is set in the global zone and applies to processes in all zones. The audit records can be marked with the name of the zone in which the event occurred. To include zone names in audit records, you must edit the /etc/security/audit_startup file before you install any non-global zones. The zone name selection is case-sensitive.
To configure auditing in the global zone to include all zone audit records, add this line to the /etc/security/audit_startup file:
/usr/sbin/auditconfig -setpolicy +zonename
As the global administrator in the global zone, execute the auditconfig utility:
global# auditconfig -setpolicy +zonename
When a non-global zone is installed, the audit_control file and the audit_user file in the global zone are copied to the zone's /etc/security directory. These files might require modification to reflect the zone's audit needs.
For example, each zone can be configured to audit some users differently from others. To apply different per-user preselection criteria, both the audit_control and the audit_user files must be edited. The audit_user file in the non-global zone might also require revisions to reflect the user base for the zone if necessary. Because each zone can be configured differently with regard to auditing users, it is possible for the audit_user file to be empty.
By including the zonename token as described in Configuring Audit in the Global Zone, Oracle Solaris audit records can be categorized by zone. Records from different zones can then be collected by using the auditreduce command to create logs for a specific zone.
