Encryption between ES nodes using SSL/TLS

Elastic Stack Elasticsearch
1

Hi,

Is there a way to encrypt traffic between three Elasticsearch nodes using SSL/TLS?
For example we have set up ES cluster and the details are as mentioned below:-

es1.example.com
es2.example.com
es3.example.com

Can we encrypt traffic between es1.example.com <-> es2.example.com <-> es3.example.com ?

Any help will be highly appreciated. Thanks in Advance and i look forward to hearing from you.

Best Regards,

Yes, security requires a commercial license.
