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:

  1. Creating the keystore.jks and truststore.jks files

    Enabling encryption between nodes secures the data that is transferred across nodes so that it cannot be accessed by unauthorized hosts. Create a keystore.jks for the private key and the associated certificate or certificate chain.

  2. Uploading the keystore and truststore files

    Enabling encryption between nodes secures the data that is transferred across nodes so that it cannot be accessed by unauthorized hosts. Upload a keystore.jks for the private key and the associated certificate or certificate chain.

  3. Enabling encryption

    Enabling encryption between nodes secures the data that is transferred across nodes so that it cannot be accessed by unauthorized hosts. To enable encryption between nodes, use dynamic system settings.

  4. Restarting nodes

    Enabling encryption between nodes secures the data that is transferred across nodes so that it cannot be accessed by unauthorized hosts. To complete node encryption between nodes, restart nodes.
