You are designing a data pipeline for a healthcare provider that needs to process patient records securely. The pipeline must extract data from Amazon RDS, transform it using AWS Glue, and load it into Amazon S3 for long-term storage. How would you ensure that the pipeline adheres to security best practices and maintains data integrity?
A
Use AWS IAM roles and policies to restrict access to the RDS, Glue, and S3 resources, ensuring that only authorized services can interact with the data.
B
Manually transfer data from RDS to S3 via a script running on an EC2 instance, bypassing Glue for transformation.
C
Use public internet to transfer data between RDS, Glue, and S3 without any encryption.
D
Store AWS credentials in plain text within the Glue job scripts for ease of access.
