Enabling encrypted communication between nodes
For on-premises deployments, enable encryption for communication among nodes to prevent unauthorized access to the data that is transported across node clusters.
Enabling encryption between nodes secures the data that is transferred across nodes so that it cannot be accessed by unauthorized hosts. Node encryption is useful when compliance rules require all intracluster communication to be encrypted, such as when working under HIPAA regulations.
Enabling encryption involves the following high-level steps:
