Fix Recommendation

Configure RHEL 9 to allocate sufficient audit_backlog_limit to capture processes that start prior to the audit daemon with the following command:

$ sudo grubby --update-kernel=ALL --args=audit_backlog_limit=8192

Check Contents

Verify RHEL 9 allocates a sufficient audit_backlog_limit to capture processes that start prior to the audit daemon with the following command:

$ sudo grubby --info=ALL | grep args | grep 'audit_backlog_limit'

If the command returns any outputs, and audit_backlog_limit is less than "8192", this is a finding.
