The macOS system must provide an immediate real-time alert to the System Administrator (SA) and Information System Security Officer (ISSO), at a minimum, of all audit failure events requiring real-time alerts.

The audit service must be configured to immediately print messages to the console or email administrator users when an auditing failure occurs. It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability and system operation may be adversely affected.
