Description
Information stored in one location is vulnerable to accidental or incidental deletion or alteration.
ℹ️ Check
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.
✔️ Fix
Configure Amazon Linux 2023 to authenticate the remote logging server for off-loading audit logs by setting the following option in "/etc/rsyslog.conf" or "/etc/rsyslog.d/[customfile].conf":
$ActionSendStreamDriverAuthMode x509/name
