Secure data in a multi-tenant environment by automatically enforcing prefix-level encryption keys in Amazon S3
Storage Blog
The article discusses a solution to securely store and isolate data from multiple tenants in a single Amazon S3 bucket. It uses different customer-managed AWS KMS keys to encrypt objects based on their prefix in the bucket, ensuring that data from each tenant is encrypted with a separate key.
Specifically, the article covers:
- Overview of the solution architecture using Lambda, S3 Event Notifications, DynamoDB, SQS, and CloudWatch
- Prerequisites and steps to deploy the solution using AWS CDK
- Demo of the solution showcasing how objects are automatically re-encrypted with the correct KMS key for their prefix
- Additional considerations and caveats, such as object size limitations and handling of S3 Versioning
- Conclusion highlighting the benefits of the solution in maintaining data isolation and security in a multi-tenant environment
