Server Side Encryption for Boot Disk using CMK

More Info:

Microsoft Azure provides multiple distinct layers of encryption protection for virtual machine (VM) managed disks. VM managed disks are encrypted with Azure Storage encryption, also known as Server-Side Encryption (SSE), using platform-managed keys (PMK), to protect your data at rest and help you meet your organizational security and compliance commitments. By default, VM managed disk volumes (OS and data disk volumes) use platform-managed encryption keys.

To remediate Server Side Encryption for Boot Disk using CMK misconfiguration in Azure using Python, you can follow the below steps:

Import the necessary libraries:

from azure.mgmt.compute import ComputeManagementClient
from azure.mgmt.compute.models import DiskEncryptionSetParameters, EncryptionSettings, DiskEncryptionSettings, KeyVaultSecretReference
from azure.identity import DefaultAzureCredential

Set the credentials for authentication:

credential = DefaultAzureCredential()
subscription_id = 'your-subscription-id'
resource_group = 'your-resource-group'

Create an instance of the ComputeManagementClient:

compute_client = ComputeManagementClient(credential, subscription_id)

Get the virtual machine details:

vm_name = 'your-vm-name'
vm = compute_client.virtual_machines.get(resource_group, vm_name)

Get the OS disk details:

os_disk_name = vm.storage_profile.os_disk.name
os_disk = compute_client.disks.get(resource_group, os_disk_name)

Create a DiskEncryptionSetParameters object:

disk_encryption_set_parameters = DiskEncryptionSetParameters(
    identity=None,
    encryption_type='EncryptionAtRestWithCustomerKey',
    disk_encryption_key=None,
    key_encryption_key=None
)

Create an EncryptionSettings object:

encryption_settings = EncryptionSettings(
    enabled=True,
    disk_encryption_set_id='your-disk-encryption-set-id'
)

Create a DiskEncryptionSettings object:

disk_encryption_settings = DiskEncryptionSettings(
    disk_encryption_key=None,
    key_encryption_key=None,
    enabled=True,
    encryption_settings=encryption_settings
)

Create a KeyVaultSecretReference object:

key_vault_secret_reference = KeyVaultSecretReference(
    source_vault=None,
    secret_url='your-cmk-secret-url'
)

Update the OS disk with the new encryption settings:

os_disk.encryption_settings = disk_encryption_settings
os_disk.encryption_settings.disk_encryption_settings.disk_encryption_key.secret_url = key_vault_secret_reference.secret_url
os_disk.encryption_settings.disk_encryption_settings.disk_encryption_key.source_vault = key_vault_secret_reference.source_vault
compute_client.disks.create_or_update(resource_group, os_disk_name, os_disk)

Note: Make sure to replace the placeholders (your-subscription-id, your-resource-group, your-vm-name, your-disk-encryption-set-id, your-cmk-secret-url) with the actual values.These steps will remediate the Server Side Encryption for Boot Disk using CMK misconfiguration in Azure using Python.
