For audit events, you should use syslog with either TCP on port 514 or TLS on port 1514. However, rsyslog defaults to using TCP on port 514. The no form of the command resets to the default TLS port number. Syslog traffic can be encrypted using TLS/SSL, which provides mutual authentication between the remote server and the clients, thereby preventing man-in-the-middle attacks.
