RHEL 9 audit system must take appropriate action when an error writing to the audit storage volume occurs.
An XCCDF Rule
Description
It is critical that when the operating system is at risk of failing to process audit logs as required, it takes action to mitigate the failure. Audit processing failures include software/hardware errors; failures in the audit capturing mechanisms; and audit storage capacity being reached or exceeded. Responses to audit failure depend upon the nature of the failure mode.

A Manual Procedure
Configure RHEL 9 to shut down by default upon audit failure (unless availability is an overriding concern).
Add or update the following line (depending on configuration "disk_error_action" can be set to "SYSLOG" or "SINGLE" depending on configuration) in "/etc/audit/auditd.conf" file:
disk_error_action = HALT
If availability has been determined to be more important, and this decision is documented with the information system security officer (ISSO), configure the operating system to notify SA staff and ISSO staff in the event of an audit processing failure by setting the "disk_error_action" to "SYSLOG".
