Do we need to have mutual TLS between Search heads in SHC and indexers in Indexer cluster? Since both are clusters, search heads communicates first with master and then with indexers. so how can we secure communication between shs and indexers with own certs?
How to secure communication between our HEC indexers and the java based application? We are planning to have our HEC indexers fronted by a https load balancer. How to achieve secure communication in this regard with own certs?
Is there any other channels that we need to secure with own certs apart from above?
I know these are big list of questions, but any help here will really help us build a secure cluster. Any help is highly appreciated. Thanks in Advance.
