Hi,

Where and what should I look at and for if I want to build and integrate  
security for inter-node communication in an ES cluster?

The security best practices and security plugins, except for Shield, seem  
to address only client access to ES.

What should I do if I want to use SSL/TLS for encrypting inter-node  
communication in an ES cluster?

Any pointers or guidance would be appreciated.

Regards

Tri M. Nguyen

Hi Robert,

No, I never received an answer for this question.  
I was trying to use Hendrik's Elasticsearch Security plugin.  
However, that project was halted and I moved to another job, which did not allow me to further use Elastic Stack.  
I am back in the Elastic user community now with yet another employer, which does allow me to spend time to investigate and show ROI on Elastic.

You can check [Search Guard SSL](https://github.com/floragunncom/search-guard-ssl). It adds SSL support for transfer layer so nodes are communicating over SSL.
