# Encrypting data in transit
<a name="encryption-in-transit"></a>



AWS provides Transport Layer Security (TLS) encryption for data in motion. You can configure encryption settings for crawlers, ETL jobs, and development endpoints using [security configurations](https://docs.aws.amazon.com/glue/latest/dg/console-security-configurations.html) in AWS Glue. You can turn on AWS Glue Data Catalog encryption via the settings for the Data Catalog.

As of September 4, 2018, AWS KMS (*bring your own key* and *server-side encryption*) for AWS Glue ETL and the AWS Glue Data Catalog is supported.
