Disable/Hide Elastic search default endpoint access from browser

Question

When I navigate to the ElasticSearch endpoint from the browser, it returns the cluster details like below. Is there any way to disable/hide these details

{
  "name" : "cybertron-node-1",
  "cluster_name" : "cybertron-cluster",
  "cluster_uuid" : "rxF850LBSuuqBCT8wGQOXA",
  "version" : {
    "number" : "6.1.1",
    "build_hash" : "bd92e7f",
    "build_date" : "2017-12-17T20:23:25.338Z",
    "build_snapshot" : false,
    "lucene_version" : "7.1.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

6.1 is EOL and unsupported, please upgrade as a matter of urgency!

the only way to do this would be to use access control, or roll your own proxy, which is free in 6.8/7.1 and above https://www.elastic.co/blog/security-for-elasticsearch-is-now-free
