Integrate Microsoft Presidio with AWS S3 read-only roles

Microsoft Presidio is a robust open-source tool for detecting and anonymizing sensitive data. AWS S3 is often the storage backbone for that data. To connect them securely, you need read-only roles that grant the minimum permissions Presidio requires. This prevents accidental writes, deletions, or privilege creep.

First, create an IAM policy in AWS that allows the s3:GetObject and s3:ListBucket actions. Point it to the specific buckets and prefixes Presidio scans. Attach it to a dedicated IAM role. Do not grant wildcard permissions. Lock it down to exactly what Presidio will process.

Next, configure Presidio’s analyzer service to use IAM authentication. If running Presidio inside AWS, assign the read-only role to the EC2 instance or ECS task. If running outside AWS, create an IAM user for Presidio and give it programmatic access keys bound to that read-only policy.

When pulling data, Presidio will authenticate with AWS and read contents securely over HTTPS. No write privileges, no risk of bucket modification. Inspect logs in CloudTrail to confirm there are no unexpected operations. Roll credentials regularly and enforce strong boundary conditions on buckets.

This setup means sensitive files in S3 can be scanned at scale without risking storage corruption or leaks caused by overly broad permissions. It also aligns with the principle of least privilege, which is vital for compliance-heavy environments.

Secure integration between Microsoft Presidio and AWS S3 read-only roles is not complex, but it demands precision. Implement the policy, attach the role, verify the actions, and keep it tight. Watch Presidio work without touching a single byte it’s not supposed to.
