Implementing secure data isolation techniques

Data isolation is a cornerstone of multi-tenancy, ensuring that each tenant’s data remains secure and inaccessible to other tenants. This section explores various techniques to achieve secure data isolation across different layers of your AWS infrastructure.

Network-level isolation

Network isolation serves as an initial safeguard in a multi-tenant environment, focusing on the segregation of network traffic to ensure that each tenant’s data flows remain separate from one another. However, It is crucial to note that the effectiveness of network-level isolation is contingent on the nature of the resources being used. Specifically, network isolation is most applicable when resources are dedicated to individual tenants and are VPC-attached.

For shared resources that don’t have separate network configurations for each tenant, or AWS services that are not attached to a VPC, network-based isolation is not feasible...
