Check: AOSX-09-000295
Apple OS X 10.9 Workstation STIG:

(in version v1 r2)
Title
The operating system must allocate audit record storage capacity to store at least one weeks worth of audit records, when audit records are not immediately sent to a central audit record storage facility. (Cat II impact)
Discussion
The audit service must be configured to require that records are kept for 7 days or longer before deletion when there is no central audit record storage facility. When expire-after is set to 7d, the audit service will not delete audit logs until the log data is at least 7 days old.
Check Content
The check displays the amount of time the audit system is configured to retain audit log files. The audit system will not delete logs until the specified condition has been met. To view the current setting, run the following command: sudo grep ^expire-after /etc/security/audit_control If this returns no results, or does not contain 7d or a larger value, this is a finding.
Fix Text
Edit the /etc/security/audit_control file, and change the value for 'expire-after' to the amount of time audit logs should be kept for the system. Use the following command to set the 'expire-after' value to '7d': sudo sed -i.bak 's/.*expire-after.*/expire-after:7d/' /etc/security/audit_control; sudo audit -s
