title: Elasticsearch security measures?
body: <p>I have set up my ELK stack on a single server and tested it on a very small setup to get a hands-down on ELK.
  I want to use ELK for my system logs analysis.</p>
  
  <p>Now, I have been reading about ES that it has no security. Also read something like this:
  "DO NOT have ES publicly accessible. That's the equivalent of making your Wordpress MySQL database accessible to the world. ES is a REST accessible DB which means that anyone can delete all of your data with access to the endpoint."</p>
  
  <p>I am a noob in this. So this means if I put my logs in ES will they be accessible to everyone (which is scary) ??</p>
  
  <p>Please guide me with what all security measures must be taken? Please suggest some links so that I can ensure security.
  How to keep my ES cluster private?</p>
