Encryption of data at rest with Azure SQL Database. Snowflake supports either client-side encryption or server-side encryption. Lastly, the most common question I get asked when I start raving about this is whether this will impact the performance of the host or VM and the answer from Microsoft’s document is always follow: Encryption at host does not use your VM's CPU and doesn't impact your VM's performance. A disk references a key via its disk encryption set. Server-side encryption with Azure Key Vault . Server-side encryption is also FIPS 140-2 compliant. As mentioned earlier in this post, SSE with PMK is turned on by default for managed disks: Attempting to create a new data disk for a VM will automatically turn on PMK as well as state that a Disk encryption set is not required: To set up SSE with CMK, begin by creating an Azure Key Vault that will store the keys: Depending on what this vault is used for, you would enable the following: For the purpose of this demonstration, I will enable all of them as I will be using this to demonstrate ADE later on as well. Wrapper for an encryption key to be used with client provided key server-side encryption. ADE is Azure disk encryption. Instead of deleting a key, it is recommended to set enabled to false on the key encryption key. This is similar to the concept of a SAN with aggregates/volumes and LUN in VMware but this also means the Azure administrator would need to continue to assess how many disks are in the page blob, how performance is affected by each disk and many other aspects. Snapshots created from disks that are encrypted with server-side encryption and customer-managed keys must be encrypted with the same customer-managed keys.

What Encryption at host does is essentially provide end-to-end encryption between the disk as rest and when the disk is allocated to and ran on a host. Also, this encryption can be set on . Some Azure services enable the Host Your Own Key (HYOK) key management model. The server-side encryption model with customer-managed keys in Azure Key Vault involves the service accessing the keys to encrypt and decrypt as needed. The documentation for this struct was generated from the following file: inc/azure/storage/blobs/ blob_options.hpp. Encryption at host ensures that data stored on the VM host is encrypted at . The following is a diagram depicting the double encryption using both CMK and PMK: With all the theory out of the way, let’s proceed onto demoing how all this looks during the configuration. While the Resource Provider performs the encryption and decryption operations, it uses the configured key encryption key as the root key for all encryption operations. The reason why there are two keys in this process is because having to continuously access the Microsoft key store (Azure Key Vault) and retrieve the KEK would be very inefficient for large amounts of data operation. Hovering over the information icon will display the following: SSE with PMK is server-side encryption with a platform-managed key. Client Encryption model refers to encryption that is performed outside of the Resource Provider or Azure by the service or calling application. Build cloud-native applications or modernize existing applications with fully managed databases. Server-side encryption using customer-managed keys in customer-controlled hardware is fairly self-explanatory where the customer will not use the Azure Key Vault to store their keys but rather a solution outside of Microsoft Azure (e.g. The encryption of azure storage is made using the server-side encrypt technique when the data is present in the cloud.
