Best practices for least privilege configuration in Amazon MWAA

This article provides comprehensive guidance on implementing least privilege security configurations for Amazon Managed Workflows for Apache Airflow (MWAA), focusing on network security and permission management.

• Minimize network access through careful configuration of security groups, network ACLs, and VPC endpoints
• Restrict traffic within AWS by using customer-managed endpoints for MWAA resources
• Create narrowly scoped IAM execution roles with minimal required permissions
• Use VPC endpoints to keep network traffic within AWS network
• Apply principle of least privilege to all MWAA environment configurations

Key recommendations include creating specific security group rules, using network ACLs to control subnet-level traffic, and developing granular IAM policies that grant only essential permissions for Airflow operations.
