Amazon provides Secure Sockets Layer (SSL) encryption for data in flight. 

DataBrew support for JDBC data sources comes through Amazon Glue. When connecting to JDBC data sources, DataBrew uses the settings on your Amazon Glue connection, including the **Require SSL connection** option. For more information, see [Amazon Glue Connection Properties - Amazon Glue](https://docs.amazonaws.cn/glue/latest/dg/connection-defining.html) in the *Amazon Glue Developer Guide*.

Amazon KMS provides both "bring your own key" encryption and server-side encryption for DataBrew extract, transform, load (ETL) processing and for the Amazon Glue Data Catalog.
