Control: Azure > CIS v4.0 > 03 - Analytics Services > 03.01 - Azure Databricks > 03.01.03 - Ensure that traffic is encrypted between cluster worker nodes

Configures auditing against a CIS Benchmark item.

Level: 2

By default, data exchanged between worker nodes in an Azure Databricks cluster is not encrypted. To ensure that data is encrypted at all times, whether at rest or in transit, you can create an initialization script that configures your clusters to encrypt traffic between worker nodes using AES 256-bit encryption over a TLS 1.3 connection.

- Protects sensitive data during transit between cluster nodes, mitigating risks of data interception or unauthorized access. - Aligns with organizational security policies and compliance requirements that mandate encryption of data in transit. - Enhances overall security posture by ensuring that all inter-node communications within the cluster are encrypted.
