Layers: (1) S3 encryption (SSE-KMS). (2) IAM + bucket policies; Lake Formation for fine-grained. (3) VPC endpoints for S3/Glue. (4) Glue Catalog permissions. (5) CloudTrail and S3 access logs. (6) Tagging, lifecycle. Best practice: Least privilege; encrypt; audit; Lake Formation for column-level.

Pro Tip

Red Flag: Public bucket or no encryption. Pro-Move: 'SSE-KMS; Lake Formation column-level; VPC endpoints—zero public access; quarterly audit.'
