Azure Disk Encryption For Boot Disk Volumes

More Info:

Ensure that your Microsoft Azure virtual machine (VM) boot volumes are encrypted using Azure Disk Encryption in order to meet security and compliance requirements. ADE encrypts the OS and data disks of Azure virtual machines (VMs) inside your VMs using the CPU via the DM-Crypt feature for Linux or the BitLocker feature for Windows. ADE is integrated with Azure Key Vault to help you control and manage the disk encryption keys and secrets. The boot (OS) volumes encryption and decryption is handled transparently and does not require any additional action from you, your Azure virtual machine, or your cloud application.

Here are the step by step instructions to remediate Azure Disk Encryption for Boot Disk Volumes using Azure CLI:

Check if the Azure Disk Encryption is enabled for the Boot Disk Volume of the Virtual Machine using the following command:
```
az vm encryption show --name <VM Name> --resource-group <Resource Group Name> --query "disksEncryptionSettings[?osDisk=true].enabled"
```
If the output is true, then Azure Disk Encryption is enabled for the Boot Disk Volume.
Disable the Azure Disk Encryption for the Boot Disk Volume of the Virtual Machine using the following command:
```
az vm encryption disable --name <VM Name> --resource-group <Resource Group Name> --volume-type OS
```
This command will disable the Azure Disk Encryption for the Boot Disk Volume of the Virtual Machine.
Verify if the Azure Disk Encryption is disabled for the Boot Disk Volume of the Virtual Machine using the following command:
```
az vm encryption show --name <VM Name> --resource-group <Resource Group Name> --query "disksEncryptionSettings[?osDisk=true].enabled"
```
If the output is false, then Azure Disk Encryption is disabled for the Boot Disk Volume.
Restart the Virtual Machine to complete the remediation process.
```
az vm restart --name <VM Name> --resource-group <Resource Group Name>
```
This command will restart the Virtual Machine to complete the remediation process.

By following the above steps, you can remediate Azure Disk Encryption for Boot Disk Volumes using Azure CLI.

Using Python

To remediate the misconfiguration “Azure Disk Encryption For Boot Disk Volumes”, you can use the following steps:

Install the Azure PowerShell module using the following command:

Install-Module -Name Az -AllowClobber -Scope CurrentUser

Connect to your Azure account using the following command:

Connect-AzAccount

Retrieve the virtual machine that needs to be remediated using the following command:

$vm = Get-AzVM -ResourceGroupName <resource-group-name> -Name <vm-name>

Check if the boot disk is already encrypted using the following command:

$diskEncryptionStatus = Get-AzVMDiskEncryptionStatus -ResourceGroupName $vm.ResourceGroupName -VMName $vm.Name
$bootDiskStatus = $diskEncryptionStatus[0].DiskEncryptionKeyEncryptionMethod

If the boot disk is not encrypted, enable encryption for the boot disk using the following command:

$diskEncryptionKeyVaultUrl = "https://<key-vault-name>.vault.azure.net/"
$diskEncryptionKeyVaultResourceId = (Get-AzKeyVault -VaultName <key-vault-name>).ResourceId
$diskEncryptionKeyEncryptionAlgorithm = "RSA-OAEP"
$diskEncryptionKey = (Get-AzKeyVaultKey -VaultName <key-vault-name> -Name <key-name>).Key
Set-AzVMDiskEncryptionExtension -ResourceGroupName $vm.ResourceGroupName -VMName $vm.Name -DiskEncryptionKeyVaultUrl $diskEncryptionKeyVaultUrl -DiskEncryptionKeyVaultId $diskEncryptionKeyVaultResourceId -DiskEncryptionKeyEncryptionAlgorithm $diskEncryptionKeyEncryptionAlgorithm -DiskEncryptionKey $diskEncryptionKey -VolumeType "OS"

Note: Replace <resource-group-name>, <vm-name>, <key-vault-name>, and <key-name> with the appropriate values.

Verify that the boot disk is encrypted using the following command:

$diskEncryptionStatus = Get-AzVMDiskEncryptionStatus -ResourceGroupName $vm.ResourceGroupName -VMName $vm.Name
$bootDiskStatus = $diskEncryptionStatus[0].DiskEncryptionKeyEncryptionMethod

Once you have verified that the boot disk is encrypted, you can disconnect from your Azure account using the following command:

Disconnect-AzAccount

This will remediate the misconfiguration “Azure Disk Encryption For Boot Disk Volumes” for your Azure virtual machine using Python.
