Fix Recommendation

Configure the operating system to encrypt offloaded audit records by setting the following options in "/etc/rsyslog.conf" or "/etc/rsyslog.d/[customfile].conf":

$DefaultNetstreamDriver gtls
$ActionSendStreamDriverMode 1

Check Contents

Verify the operating system encrypts audit records offloaded onto a different system or media from the system being audited with the following commands:

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

/etc/rsyslog.conf:$DefaultNetstreamDriver gtls

If the value of the "$DefaultNetstreamDriver" option is not set to "gtls" or the line is commented out, this is a finding.

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

/etc/rsyslog.conf:$ActionSendStreamDriverMode 1

If the value of the "$ActionSendStreamDriverMode" option is not set to "1" or the line is commented out, this is a finding.

If neither of the definitions above are set, ask the System Administrator 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.
