Verify Amazon Linux 2023 authenticates the remote logging server for off-loading audit logs with the following command:

$ sudo grep -i '$ActionSendStreamDriverAuthMode' /etc/rsyslog.conf /etc/rsyslog.d/*.conf 
/etc/rsyslog.conf:$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 off-loaded to a different system or media. 

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