Discussion

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.

Check Content

Verify the macOS system is configured to store at least seven days of audit records with the following command:

/usr/bin/sudo /usr/bin/grep ^expire-after /etc/security/audit_control

expire-after:7d

If "expire-after" is not set to "7d" or greater, this is a finding.

Fix Text

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.
