Security Best Practices

1. Introduction

Security Best Practices in Apache Beam pipelines cover data encryption, credential management, and secure VPC network execution isolation.

2. Why This Concept Exists

Data pipelines process highly sensitive client databases. Restricting access permissions and encrypting network communications prevent data leakage.

3. Core Guidelines

• Principle of Least Privilege: Run pipelines using dedicated service accounts with minimal roles rather than default administrator credentials.
• VPC Execution: Deploy worker VMs within private subnets that block public internet routing.
• Customer-Managed Encryption Keys (CMEK): Use CMEKs to encrypt transient state disks on worker VMs.
