when user open or report from Power Bi Service, how is the data processing and storage

Hi pennyhoho117 ,

1. Data is retrieved from memory (Import) or queried live (DirectQuery) and encrypted in transit (TLS).
2. Data at rest is encrypted using Microsoft-managed or customer-managed keys (Azure Key Vault).

For editing, only metadata (not datasets) is updated, and encryption remains the same during save or publish.
