Encrypting Elasticsearch Data in Transit and at Rest

Is there a node to node and client to ES in-transit data encryption available for elasticsearch . We are using AWS ec2 IaaS for our elasticsearch instance . The version that we are using is 5.6 but we plan to upgrade it to the latest version of elasticsearch. We are using transport protocol for connecting to Elasticsearch from a Java application

If you are using x-pack security, answer is yes. If you are using FOSS version and dont want to pay for x-pack subscription, then you will need to explore the 3rd party security plugins like Searchguard or ReadOnlyRest to apply the security that you are looking for. Both have FOSS and commerical versions.

Thank you. I will explore these options.
