# Mutual authentication using TLS

This section describes how to configure mutual authentication between the AxoSyslog server and the client. Configuring mutual authentication is similar to configuring TLS (for details, see [Encrypting log messages with TLS](https://axoflow.com/docs/axosyslog-core/4.28/chapter-encrypted-transport-tls/tls-serverauth/index.md)), 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 [Secure logging using TLS](https://axoflow.com/docs/axosyslog-core/4.28/chapter-encrypted-transport-tls/concepts-tls/index.md).
