Audit provisioning of a Microsoft Entra administrator for your PostgreSQL server to enable Microsoft Entra authentication. Microsoft Entra authentication enables simplified permission management and centralized identity management of database users and other Microsoft services
To complement access controls, data at rest should be protected against 'out of band' attacks (such as accessing underlying storage) using encryption. This helps ensure that attackers cannot easily read or modify the data.
Many Azure services have data at rest encryption enabled by default at the infrastructure layer using a service-managed key.
Where technically feasible and not enabled by default, you can enable data at rest encryption in the Azure services, or in your VMs for storage level, file level, or database level encryption.
