How can I implement authentication in Elasticsearch?

You can implement authentication in Elasticsearch using the built-in security features. Are you using the open-source version or the commercial one?

I'm using the open-source version. What options do I have?

In the open-source version, you can use basic authentication with a reverse proxy like Nginx or Apache. Would you like guidance on setting that up?

Yes, please! How do I configure Nginx for this?

To configure Nginx, you'll need to set up a server block that proxies requests to Elasticsearch and adds basic authentication. I can provide a sample configuration if you'd like.
