Storing Encryption Keys for AI Datasets in Azure Key Vault

Question

Pulumi · Accepted Answer

To store encryption keys for AI datasets in Azure Key Vault using Pulumi, you will be creating an instance of Azure Key Vault, which is a secure store for storing encryption keys, secrets, and certificates. You will also create a secret inside the Key Vault to represent the encryption key.

Azure Key Vault provides a secure and central location for storing confidential data. The keys in Azure Key Vault are RSA keys, which are asymmetric cryptography keys that can be used for encrypting and decrypting data. You can also store secrets in the Key Vault, which can be simple data types such as strings or binary data.

In the code below, we'll create an Azure Key Vault and then a secret within that Key Vault:

1. **Azure Key Vault (`Vault`)**: This is the resource that represents the Key Vault itself.
2. **Secret (`Secret`)**: This represents the encryption key we want to store in the Key Vault.

The data that the AI will be processing would reference these stored secrets for encryption and decryption. This ensures that the sensitive information stored as part of the AI datasets is secure and managed according to best practices.

Here's how you would set up the above resources in Pulumi using Python:

```python
import pulumi
import pulumi_azure_native as azure_native

# Create an Azure resource group
resource_group = azure_native.resources.ResourceGroup("resourceGroup")

# Create an Azure Key Vault
key_vault = azure_native.keyvault.Vault("keyVault",
    resource_group_name=resource_group.name,
    location=resource_group.location,
    properties=azure_native.keyvault.VaultPropertiesArgs(
        sku=azure_native.keyvault.SkuArgs(
            family="A",
            name="standard"
        ),
        tenant_id="YOUR_AZURE_TENANT_ID",  # replace with your Azure Tenant ID
        access_policies=[]
    )
)

# Store an encryption secret in the Azure Key Vault
secret = azure_native.keyvault.Secret("secret",
    resource_group_name=resource_group.name,
    vault_name=key_vault.name,
    properties=azure_native.keyvault.SecretPropertiesArgs(
        value="ENCRYPTION_KEY_VALUE"  # replace with your actual encryption key
    )
)

# Export the Key Vault ID and the Secret ID
pulumi.export("keyVaultId", key_vault.id)
pulumi.export("secretId", secret.id)
```

In this program:

- We import the necessary modules from Pulumi.
- We create an Azure Resource Group as a container for the resources.
- We then create an Azure Key Vault instance with a SKU, defining the pricing/usage tier (in this case, 'standard').
- We store the secret, which would be your encryption key, in the Key Vault. The `value` property is where you'd put the actual encryption key that you want to secure.
- Finally, we export the IDs for both the Key Vault and the Secret. These identifiers can be used to access the Key Vault and Secret from other resources or applications.

Be aware that in a real-world scenario, you need to replace 'YOUR_AZURE_TENANT_ID' with your actual Azure tenant ID, and 'ENCRYPTION_KEY_VALUE' with the encryption key you wish to store securely.

Please ensure that you manage and handle these sensitive values securely, possibly using environment variables or a secure configuration store. Do not hard-code sensitive data in your source code.

To use this Pulumi code, you would need to have the Azure provider set up and configured with the necessary permissions to create Key Vaults and manage secrets. This usually involves having an authenticated Azure account with sufficient privileges.
