Splunk Enterprise must notify the System Administrator (SA) and Information System Security Officer (ISSO) (at a minimum) of all audit failure events, such as loss of communications with hosts and devices, or if log records are no longer being received.
An XCCDF Rule
Description
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 function and application operation may be adversely affected.

A Manual Procedure
If the Splunk instance is used for Tier 2 CSSP (formerly CND-SP) or JRSS analysis, this fix is N/A.
Configure Splunk Enterprise using the reporting and notification tools to create a report with notification to the SA and ISSO of any audit failure events, such as loss of communication or logs no longer being collected.
