The macOS system must allocate audit record storage capacity to store at least seven days of audit records when audit records are not immediately sent to a central audit record storage facility.
An XCCDF Rule
Description
The audit service must be configured to require that records are kept for seven 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 seven days old.

A Manual Procedure
Configure the macOS system to store seven days of audit records with the following command:
/usr/bin/sudo /usr/bin/sed -i.bak 's/.*expire-after.*/expire-after:7d/' /etc/security/audit_control; /usr/bin/sudo /usr/sbin/audit -s
Alternatively, use a text editor to update the "/etc/security/audit_control" file.
