OL 9 must have the packages required for encrypting offloaded audit logs installed.

The rsyslog-gnutls package provides Transport Layer Security (TLS) support for the rsyslog daemon, which enables secure remote logging.

Verify that OL 9 has the rsyslog-gnutls package installed with the following command:

$ dnf list --installed rsyslog-gnutls Installed Packages rsyslog-gnutls.x86_64 8.2310.0-4.el9 @AppStream

If the rsyslog-gnutls package is not installed, this is a finding.

Install the rsyslog-gnutls package with the following command:

$ sudo dnf install -y rsyslog-gnutls
