Is it possible to enable encryption in between worker nodes?

[User16826992666]

I have a security requirement to encrypt all data when it is in transit. I am wondering if there is a setting I can use to enable encryption of the data during shuffles between the worker nodes.

If your environment requires that data be encrypted at all times, whether at rest or in transit, you can create an init script that configures your clusters to encrypt traffic between worker nodes, using AES 128-bit encryption over a TLS 1.2 connection.

More guidelines mentioned here - https://docs.databricks.com/security/encryption/encrypt-otw.html

If it is on aws, consider using Nitro instances which gives this automatically. For more details check https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/data-protection.html#encryption-transit

Inter-node encryption is a requirement for HIPPA compliance, reach out to your account management team and ask them for HIPPA compliant shards.
