10.3. Mutual authentication using TLS The syslog-ng Premium Edition 7 Administrator Guide
This section describes how to configure mutual authentication between the syslog-ng server and the client. Configuring mutual authentication is similar to configuring TLS (for details, see Section 10.2, Encrypting log messages with TLS), but the server verifies the identity of the client as well. Therefore, each client must have a certificate, and the server must have the certificate of the CA that issued the certificate of the clients. For the concepts of using TLS in syslog-ng, see Section 10.1, Secure logging using TLS.
