Sudipta Mitra, et al, talk AWS security:
This post presents an approach that you can apply at scale to achieve fine-grained access controls to resources in S3 buckets and Amazon Redshift schemas for tenants, including groups of users belonging to the same business unit down to the individual user level. This solution provides tenant isolation and data security. In this approach, we use the bridge model to store data and control access for each tenant at the individual schema level in the same Amazon Redshift database. We utilize ASSUMEROLE and role chaining to provide fine-grained access control when data is being copied and unloaded between Amazon Redshift and Amazon S3, so the data flows within each tenant’s namespace. Role chaining also streamlines the new tenant onboarding process.
