It works by decrypting your drive only when the correct Unlock method, such as a password or a smart card, is presented. In the event that you forget or lose your unlock method, BitLocker provides a recovery key, a special key that can unlock your drive. This article will guide you on how to retrieve BitLocker recovery keys in the context of Microsoft Azure and specifically geared towards preparation for AZ-600 Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub exam.
To begin with, It is important to understand that Azure provides an additional layer of data protection with Azure Key Vault, a service that manages encryption keys and secrets used by cloud services and applications. Azure Key Vault work effectively with BitLocker by safeguarding and controlling access to the BitLocker recovery keys.
Retrieving BitLocker key in Azure Active directory
BitLocker keys are automatically backed up to Azure Active Directory (Azure AD) when a device is enrolled into Microsoft Intune. Admins can retrieve these keys when needed. Here’s how;
- Log in into the Azure portal.
- Navigate to Azure Active Directory -> Devices -> All devices.
- Search for the necessary device and select it.
- From the device’s page, you can see the BitLocker Key ID and the Recovery Key.
Retrieving Bitlocker key in Azure Key Vault
To be able to retrieve BitLocker recovery keys, first for the Azure Key Vault, you need to have Azure Key Vault configured and your keys stored. Here’s how:
- Log in to your Azure portal.
- Navigate to Key vaults -> Your Key vault.
- Under `Settings` section, click on `Secrets`.
- You’ll find all your secrets listed here with their current status. You can use the search box to find your BitLocker Recovery keys.
- Click on the key you need to retrieve, and in the new pane, you will see the current version of the key identified by dates, click on the version you need.
- In the `Secret Value` section, click on `Show Secret Value` to reveal the recovery key which can then be copied to be used.
PowerShell
Microsoft Azure also provides options to retrieve the BitLocker recovery keys using PowerShell. This offers a more programmatic approach and is quite handy for administering large environments.
Here’s a sample code on how to achieve this:
#Login to Azure account
Connect-AzureAD
#Get the devices BitLocker status
$device = Get-AzureADDevice -SearchString "DeviceName"
$deviceID = $device.ObjectId
$BLinfo = Get-AzureADDeviceBitLockerKey -DeviceId $deviceID
#Output the BitLocker information
$BLinfo
Replace “DeviceName” with the actual name of your device.
This script logs into your Azure account, fetches the BitLocker status of your device, and outputs the BitLocker recovery keys.
Final Words
The importance of BitLocker recovery keys cannot be overstated. They are a crucial part of data protection and should be managed carefully. With Microsoft Azure and its suite of services, managing and retrieving your BitLocker recovery keys becomes relatively easier.
Remember, practice makes perfect. So, keep retrieving BitLocker keys on Azure until you’re comfortable with the process. This practical proficiency will aid you in your preparation for AZ-600 Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub.
