Check Text (C-73544r1049896_chk)
Verify AlmaLinux OS 9 authenticates the remote logging server for offloading audit logs with the following command:

$ grep -i '$ActionSendStreamDriverAuthMode' /etc/rsyslog.conf /etc/rsyslog.d/*.conf

/etc/rsyslog.d/stig.conf:$ActionSendStreamDriverAuthMode x509/name

If the value of the "$ActionSendStreamDriverAuthMode" option is not set to "x509/name" or the line is commented out, ask the system administrator (SA) to indicate how the audit logs are offloaded to a different system or media.

If there is no evidence that the transfer of the audit logs being offloaded to another system or media is encrypted, this is a finding.
