The TLS (Transport Layer Security) and SSL (Secure Sockets Layer) protocols provide end-to-end encryption for communications between applications over a network. (Note that TLS is technically the replacement of SSL, but both are commonly referred to as SSL.)
For more information on BDD's TLS/SSL options, see the Installation Guide.
BDD can run on Hadoop clusters secured with TLS/SSL.
Individual Hadoop services can be secured with TLS/SSL so that their communication with other secured services is encrypted. BDD can be configured to work with secured HDFS, YARN, Hive, and Key Management Server (KMS) at install or upgrade time. This results in its communications with those services being encrypted. For more information, see the Installation Guide.
