Proper access policy for Amazon Elastic Search Cluster

Question

I\'ve recently started using the new Amazon Elasticsearch Service and I can\'t seem to figure out the access policy I need so that I can only access the services from my EC2

Answer 1

You may either use resource based policy or identity based policy rather than IP based policy which is like hard coding the IP address.

But you need to use Signature version 4 to sign the request
