Overview of BitLocker Device Encryption in Windows – Windows security | Microsoft Docs

 
It\’s recommended that administrators enable this policy only for devices that are verified to have an alternative means of preboot input, windows 10 enterprise bitlocker gpo free download as attaching a USB keyboard. Wherever confidential data is stored, it must be protected against unauthorized access. A simple script can pipe out the values of each Get-BitLockerVolume return to another variable as seen below:. Note These settings are enforced when turning on BitLocker, not when unlocking a volume. This policy setting is used to establish an identifier that is applied to all drives that are encrypted in your organization. По ссылке initialization might be needed during the BitLocker setup. It should also be done when you intentionally want to invalidate an existing recovery password for any reason.

 

BitLocker basic deployment – Windows security | Microsoft Docs – Surface devices

 

In addition to the Group Policy created previously, you need to configure permissions in Active Directory to be able to store the TPM recovery information. If you want to automate enabling the TPM chip as part of the deployment process, you need to download the vendor tools and add them to your task sequences, either directly or in a script wrapper. This utility uses a configuration file for the BIOS settings.

Lenovo also provides a separate download of the scripts. Here is a sample command to enable TPM using the Lenovo tools:. When configuring a task sequence to run any BitLocker tool, either directly or using a custom script, it is helpful if you also add some logic to detect whether the BIOS is already configured on the machine.

You can also use BitLocker Network Unlock to allow these computers to automatically unlock when connected to a trusted wired network that can provide the Network Unlock key. The protection differences provided by multifactor authentication methods can\’t be easily quantified. Consider each authentication method\’s impact on Helpdesk support, user education, user productivity, and any automated systems management processes.

In your deployment plan, identify what TPM-based hardware platforms will be supported. Document the hardware models from an OEM of your choice, so that their configurations can be tested and supported. TPM hardware requires special consideration during all aspects of planning and deployment. For TPM 1.

Windows automatically initializes the TPM, which brings it to an enabled, activated, and owned state. Devices that don\’t include a TPM can still be protected by drive encryption. Use the following questions to identify issues that might affect your deployment in a non-TPM configuration:.

Test your individual hardware platforms with the BitLocker system check option while you\’re enabling BitLocker. The system check makes sure that BitLocker can read the recovery information from a USB device and encryption keys correctly before it encrypts the volume.

To function correctly, BitLocker requires a specific disk configuration. BitLocker requires two partitions that meet the following requirements:. Windows setup will automatically configure the disk drives of your computer to support BitLocker encryption. When the computer fails to start, Windows automatically transitions into this environment, and the Startup Repair tool in Windows RE automates the diagnosis and repair of an unbootable Windows installation.

Windows RE also contains the drivers and tools that are needed to unlock a volume protected by BitLocker by providing a recovery key or recovery password. Windows RE can also be used from boot media other than the local hard disk. If you don\’t install Windows RE on the local hard disk of BitLocker-enabled computers, then you can use different boot methods.

In Windows Vista and Windows 7, BitLocker was provisioned after the installation for system and data volumes. It used the manage-bde command line interface or the Control Panel user interface. Checking BitLocker status with the control panel is the most common method used by most users. Once opened, the status for each volume is displayed next to the volume description and drive letter.

Available status return values with the control panel include:. If a drive is pre-provisioned with BitLocker, a status of \”Waiting for Activation\” displays with a yellow exclamation icon on the volume. This status means that there was only a clear protector used when encrypting the volume. In this case, the volume isn\’t in a protected state and needs to have a secure key added to the volume before the drive is fully protected.

Once complete, the control panel will update to reflect the new status. Using the control panel, administrators can choose Turn on BitLocker to start the BitLocker Drive Encryption wizard and add a protector, like PIN for an operating system volume or password if no TPM exists , or a password or smart card protector to a data volume.

The drive security window displays prior to changing the volume status. Selecting Activate BitLocker will complete the encryption process. Administrators who prefer a command-line interface can utilize manage-bde to check volume status.

Manage-bde is capable of returning more information about the volume than the graphical user interface tools in the control panel. For example, manage-bde can display the BitLocker version in use, the encryption type, and the protectors associated with a volume. If no volume letter is associated with the -status command, all volumes on the computer display their status.

Windows PowerShell commands offer another way to query BitLocker status for volumes. Like manage-bde, Windows PowerShell includes the advantage of being able to check the status of a volume on a remote computer.

To get information that is more detailed on a specific volume, use the following command:. Administrators can enable BitLocker prior to operating system deployment from the Windows Pre-installation environment.

This is done with a randomly generated clear key protector applied to the formatted volume and by encrypting the volume prior to running the Windows setup process.

If the encryption uses the Used Disk Space Only option described later in this document, this step takes only a few seconds and incorporates well into regular deployment processes. Decrypting volumes removes BitLocker and any associated protectors from the volumes.

Decryption should occur when protection is no longer required. BitLocker decryption shouldn\’t occur as a troubleshooting step. BitLocker can be removed from a volume using the BitLocker control panel applet, manage-bde, or Windows PowerShell cmdlets. We\’ll discuss each method further below. BitLocker decryption using the control panel is done using a wizard. The control panel can be called from Windows Explorer or by opening it directly. After opening the BitLocker control panel, users will select the Turn off BitLocker option to begin the process.

After selecting the Turn off BitLocker option, the user chooses to continue by clicking the confirmation dialog. With Turn off BitLocker confirmed, the drive decryption process begins and reports status to the control panel.

The control panel doesn\’t report decryption progress but displays it in the notification area of the task bar. Selecting the notification area icon will open a modal dialog with progress. Once decryption is complete, the drive updates its status in the control panel and becomes available for encryption. Decrypting volumes using manage-bde is straightforward. Decryption with manage-bde offers the advantage of not requiring user confirmation to start the process.

Manage-bde uses the -off command to start the decryption process. A sample command for decryption is:. This command disables protectors while it decrypts the volume and removes all protectors when decryption is complete. Since the password ID is a unique value that is associated with each recovery password stored in AD DS, running a query using this ID will find the correct password to unlock the encrypted volume. Before you give the user the recovery password, you should gather any information that will help determine why the recovery was needed, in order to analyze the root cause during the post-recovery analysis.

For more info about post-recovery analysis, see Post-recovery analysis. Because the recovery password is 48 digits long, the user might need to record the password by writing it down or typing it on a different computer. If you are using MBAM, the recovery password will be regenerated after it is recovered from the MBAM database to avoid the security risks associated with an uncontrolled password. Because the digit recovery password is long and contains a combination of digits, the user might mishear or mistype the password.

The boot-time recovery console uses built-in checksum numbers to detect input errors in each 6-digit block of the digit recovery password, and offers the user the opportunity to correct such errors. When a volume is unlocked using a recovery password, an event is written to the event log and the platform validation measurements are reset in the TPM to match the current configuration.

Unlocking the volume means that the encryption key has been released and is ready for on-the-fly encryption when data is written to the volume, and on-the-fly decryption when data is read from the volume.

After the volume is unlocked, BitLocker behaves the same way, regardless of how the access was granted. If you notice that a computer is having repeated recovery password unlocks, you might want to have an administrator perform post-recovery analysis to determine the root cause of the recovery and refresh BitLocker platform validation so that the user no longer needs to enter a recovery password each time that the computer starts up.

If a user needed to recover the drive, it is important to determine the root cause that initiated the recovery as soon as possible. Properly analyzing the state of the computer and detecting tampering may reveal threats that have broader implications for enterprise security.

While an administrator can remotely investigate the cause of recovery in some cases, the end user might need to bring the computer that contains the recovered drive on site to analyze the root cause further.

To help you answer these questions, use the BitLocker command-line tool to view the current configuration and protection mode for example, manage-bde -status. Scan the event log to find events that help indicate why recovery was initiated for example, if the boot file changed. Both of these capabilities can be performed remotely.

After you have identified what caused recovery, you can reset BitLocker protection and avoid recovery on every startup. The details of this reset can vary according to the root cause of the recovery. If you cannot determine the root cause, or if malicious software or a rootkit might have infected the computer, Helpdesk should apply best-practice virus policies to react appropriately.

If a user has forgotten the PIN, you must reset the PIN while you are logged on to the computer in order to prevent BitLocker from initiating recovery each time the computer is restarted.

If you have lost the USB flash drive that contains the startup key, then you must unlock the drive by using the recovery key and then create a new startup key. This error might occur if you updated the firmware. As a best practice, you should suspend BitLocker before making changes to the firmware and then resume protection after the update has completed. This action prevents the computer from going into recovery mode.

However if changes were made when BitLocker protection was on, then log on to the computer using the recovery password, and the platform validation profile will be updated so that recovery will not occur the next time.

If a PC is unable to boot after two failures, Startup Repair will automatically start. When Startup Repair is launched automatically due to boot failures, it will only execute operating system and driver file repairs, provided that the boot logs or any available crash dump point to a specific corrupted file.

In Windows 8. If the Windows RE environment has been modified, for example the TPM has been disabled, the drives will stay locked until the BitLocker recovery key is provided. Table 2 lists specific data-protection concerns and how they\’re addressed in Windows 11, Windows 10, and Windows 7.

The best type of security measures is transparent to the user during implementation and use. Every time there\’s a possible delay or difficulty because of a security feature, there\’s strong likelihood that users will try to bypass security. In fact, you can take several steps in advance to prepare for data encryption and make the deployment quick and smooth.

Basically, it was a big hassle. Microsoft includes instrumentation in Windows 11 and Windows 10 that enable the operating system to fully manage the TPM. There\’s no need to go into the BIOS, and all scenarios that required a restart have been eliminated. BitLocker is capable of encrypting entire hard drives, including both system and data drives. BitLocker pre-provisioning can drastically reduce the time required to provision new PCs with BitLocker enabled.

With Windows 11 and Windows 10, administrators can turn on BitLocker and the TPM from within the Windows Pre-installation Environment before they install Windows or as part of an automated deployment task sequence without any user interaction. Combined with Used Disk Space Only encryption and a mostly empty drive because Windows isn\’t yet installed , it takes only a few seconds to enable BitLocker.

With earlier versions of Windows, administrators had to enable BitLocker after Windows had been installed. Although this process could be automated, BitLocker would need to encrypt the entire drive, a process that could take anywhere from several hours to more than a day depending on drive size and performance, which delayed deployment.

Microsoft has improved this process through multiple features in Windows 11 and Windows Beginning in Windows 8. With Windows 11 and Windows 10, Microsoft offers BitLocker Device Encryption support on a much broader range of devices, including those that are Modern Standby, and devices that run Windows 10 Home edition or Windows Microsoft expects that most devices in the future will pass the testing requirements, which makes BitLocker device encryption pervasive across modern Windows devices.
