AlmaLinux OS 9 must encrypt, via the gtls driver, the transfer of audit records offloaded onto a different system or media from the system being audited via rsyslog.

Description
Information stored in one location is vulnerable to accidental or incidental deletion or alteration.
Off-loading is a common process in information systems with limited audit storage capacity.
ℹ️ Check
Verify AlmaLinux OS 9 uses the gtls driver to encrypt audit records offloaded onto a different system or media from the system being audited with the following command:
$ grep -i '$DefaultNetstreamDriver' /etc/rsyslog.conf /etc/rsyslog.d/*.conf
/etc/rsyslog.d/stig.conf:$DefaultNetstreamDriver gtls
If the value of the "$DefaultNetstreamDriver" option is not set to "gtls" or the line is commented out, this is a finding.
✔️ Fix
Configure AlmaLinux OS 9 to use the gtls driver to encrypt offloaded audit records by setting the following options in "/etc/rsyslog.conf" or "/etc/rsyslog.d/[customfile].conf":
$DefaultNetstreamDriver gtls
