Group Title

SRG-OS-000342-GPOS-00133

Rule Version

Fix Recommendation

Configure RHEL 9 to authenticate the remote logging server for offloading audit logs by setting the following option in "/etc/rsyslog.conf" or "/etc/rsyslog.d/[customfile].conf":

$ActionSendStreamDriverAuthMode x509/name

Check Contents

Verify RHEL 9 authenticates the remote logging server for offloading audit logs with the following command:

$ grep -i 'StreamDriver[\.]*AuthMode' /etc/rsyslog.conf /etc/rsyslog.d/*.conf

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

If the variable name "StreamDriverAuthMode" is present in an omfwd statement block, this is not a finding. However, if the "StreamDriverAuthMode" variable is in a module block, this is a finding.

If the value of the "$ActionSendStreamDriverAuthMode or StreamDriver.AuthMode" 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.
