Secure Model Credentials with Azure Key Vault

Question

Pulumi · Accepted Answer

To secure model credentials with Azure Key Vault, we'll perform the following steps in the Pulumi program written in Python:

1. Create an Azure Resource Group to have a dedicated resource container for our resources.
2. Provision an Azure Key Vault instance which will be used to store and manage the encryption keys and secrets.
3. Add a secret to the Key Vault which could represent the credentials we want to secure.

We use Azure Key Vault because it is a service that provides secure storage for secrets, keys, and certificates. With Key Vault, you can control access to sensitive information and manage secrets used by cloud applications and services.

Here's how you could create the Azure Key Vault and add a secret:

```python
import pulumi
import pulumi_azure_native as azure_native

# Resource Group
resource_group = azure_native.resources.ResourceGroup("resourceGroup")

# Key Vault
vault = azure_native.keyvault.Vault("vault",
    resource_group_name=resource_group.name,
    location=resource_group.location,
    properties=azure_native.keyvault.VaultPropertiesArgs(
        sku=azure_native.keyvault.SkuArgs(
            family="A",
            name="standard",  # Choose 'premium' for enhanced security features
        ),
        tenant_id="your-azure-tenant-id",  # Replace with your tenant ID
        access_policies=[  # Define who has access and what permissions
            azure_native.keyvault.AccessPolicyEntryArgs(
                tenant_id="your-azure-tenant-id",  # Same tenant ID as above
                object_id="your-object-id",  # Replace with the object ID of a user or service principal within your Azure AD tenant
                permissions=azure_native.keyvault.PermissionsArgs(
                    secrets=["get", "list", "set", "delete", "recover", "backup", "restore"],
                    # You could adjust the permissions based on the operations that you expect to perform. 
                ),
            ),
        ],
        # You can also configure network rules, retention policies and more based on your requirements.
    )
)

# Secret
# This is where you would store your model credentials securely.
secret = azure_native.keyvault.Secret("secret",
    resource_group_name=resource_group.name,
    vault_name=vault.name,
    properties=azure_native.keyvault.SecretPropertiesArgs(
        value="your-secret-value",  # Replace with the actual secret
    )
)

# Export the Azure Key Vault ID and Secret ID
pulumi.export('vault_id', vault.id)
pulumi.export('secret_id', secret.id)
```

In the above Pulumi program, remember to replace placeholders such as `your-azure-tenant-id`, `your-object-id`, and `your-secret-value` with actual values appropriate to your organization and security model.

- `resourceGroup`: Declares a new Azure resource group where the Azure Key Vault will reside.
- `vault`: This sets up a new Azure Key Vault where the secrets will be stored.
- `vaultProperties`: Contains specific properties such as the SKU (pricing tier), the tenant ID, and access policies. Access policies are critical as they govern who can access the Key Vault and what actions they can perform.
- `secret`: This represents the secret that you want to store in the Key Vault.

Exporting the IDs of the vault and the secret allows you to use the outputs in the future, either in Pulumi stack outputs or as inputs to other resources.

The secret value should be the actual sensitive data you wish to store securely, such as a password, connection string, or private key.

Set up the Azure Key Vault and manage secrets Angularly to ensure that they are securely stored and maintained. Always cycle your secrets according to your organization's security guidelines and monitor your Key Vault for access and usage.
