Azure NetApp Files double encryption at-rest feature now provides multiple independent encryption layers, protecting against attacks to any single encryption layer. Threats are diminished to the encrypted data, for example:
-
Single encryption key being compromised,
-
Encryption algorithms with implementation errors,
-
Data encryption configuration errors.
This feature is currently available in West Europe, East US 2, East Asia regions and will roll out to other regions as the preview progresses.
