I found this blog about authentication plugin [https://qbox.io/blog/secure-elasticsearch-authentication-plugin-tutorial](https://qbox.io/blog/secure-elasticsearch-authentication-plugin-tutorial)  
But this is deprecated and is for es-2.5,where do i start ,can you briefly explain it.

The best way would be to go with the source. Start taking a look at the [Plugin](https://github.com/elastic/elasticsearch/blob/master/server/src/main/java/org/elasticsearch/plugins/Plugin.java) and its subclasses, that are listed in the javadoc comment. From there on you can pick what you need to implement based on your security requirements.
