IBM® DB2® Big SQL includes encryption features for data in-transit (SSL) and leverages HDFS data at-rest encryption (transparent data encryption and Ranger KMS).

You can encrypt selected files or directories in HDFS, which saves on overhead and protects performance. HDFS transparent data encryption (TDE) takes advantage of HDFS native data encryption without any application code changes.

For information about using Ranger for SSL, see Configuring Db2 Big SQL for Ranger SSL by using self-signed certificates.
