BitLocker is a free encryption feature in Windows that comes standard on most versions of Windows specific requirements listed above. BitLocker allows for the encryption of drives on the system, as a layer of security. Not only is the local data on an unencrypted disk at risk, but other sensitive data like password hashes could also be recovered and used for other malicious purposes.
Therefore, drive encryption is an integral part of good security. With encryption in place, hackers would have to work extra hard to disarm the encryption, in order to recover any useful information. The problem with enabling BitLocker, or any other security feature, is that it poses a significant burden on administrators in terms of: manageability, reliability, and required knowledge. Therefore, there is a large barrier to entry for most admins who do not have time or the skills to manage BitLocker, even if the environment supports it.
It is remotely administrable with full cradle-to-grave life-cycle manageability. This is without having to implement MBAM, or any third party products. The only requirements are those listed above, at the beginning of this article.
With all of that said, this form of implementation is the least secure available. Therefore, no multi-factor authentication. This is enforceable onto to as many systems as supported.
It provides a way of creating and encrypting keys that could be used for BitLocker and for other security related features. This password can be auto generated and stored. But in recent editions of Windows, it is auto generated and tossed. More information on this later. This is automatically generated and managed by BitLocker. The key protector comes in many forms:. When this is done, that flash drive has to be plugged into the pc at boot up in order to unlock the drive and boot the system.
A passcode whether short or long, numerical, alphabetical, or alphanumerical could be used as a protector. When this is in place as a key protector, the end user must supply the passcode at each boot. A Recovery Key can be created and stored in Active Directory. This is a must, for data recovery in an emergency.Hi Kevin. This is a great post. Thanks But I want to ask-Were the computers you help encrypt all Win 10 enterprise or pro? Working on a similar deployment.
OS install drive this script is not applicable and alternative solution changes in this script kindly advice this. A friend of mine has a small client with a few hundred systems. Recently they identified a business need to encrypt all their devices so he asked me for some assistance. As they were on Windows 10 this would be an easy exorcise but one I would have to do differently due to their maturity and lack of something like MBAM licensed or third party options so we elected to use native Bitlocker with AD DS integration.
Instead of using Powershell we chose to do it oldshool so it was easier to follow. The script does these tasks Checks for a dropper file and exits out if ran. You can follow the process in this White Paper by Dell instead of me rehashing. This script is attached at the bottom. Next we had to configure Bitlocker and this was done via GPO. Finally we had to start encryption. Some people think you just set the GPO policy and the system starts encryption. This is not true, GPO just sets all the settings or preferences.
You still need to trigger encryption. It created a scheduled task to run the script. I started with a for loop like this one but it was not that eloquent. Additionally they had network shares setup via GPO. While manage-bde would error out in these two situations it was not that pretty so I went with a different for loop that used diskpart.
I modified one used previously for other tasks. I found it online and unfortunately I do not recall where to give credit. At the end it will prompt the user to restart as a restart is needed for the system drive to start encrypting. The loop passes C for example, but manage-bde wants the volume as C: so this addresses that but also changes to a more friendly variable used throughout the rest of the script.
You could technically pass this via the loop by using: call :Encrypt! Since this is running via GPO we have a check to exit out if any volumes are already encrypted. The actual meat of it is to create the protectors and encrypt it.This topic for IT professionals describes the function, location, and effect of each Group Policy setting that is used to manage BitLocker Drive Encryption.
To control what drive encryption tasks the user can perform from the Windows Control Panel or to modify other configuration options, you can use Group Policy administrative templates or local computer policy settings. How you configure these policy settings depends on how you implement BitLocker and what level of user interaction will be allowed. If a computer is not compliant with existing Group Policy settings, BitLocker may not be turned on or modified until the computer is in a compliant state.
When a drive is out of compliance with Group Policy settings for example, if a Group Policy setting was changed after the initial BitLocker deployment in your organization, and then the setting was applied to previously encrypted drivesno change can be made to the BitLocker configuration of that drive except a change that will bring it into compliance. If multiple changes are necessary to bring the drive into compliance, you must suspend BitLocker protection, make the necessary changes, and then resume protection.
This situation could occur, for example, if a removable drive was initially configured to be unlocked with a password and then Group Policy settings are changed to disallow passwords and require smart cards. In this situation, you need to suspend BitLocker protection by using the Manage-bde command-line tool, delete the password unlock method, and add the smart card method. After this is complete, BitLocker is compliant with the Group Policy setting and BitLocker protection on the drive can be resumed.
The following sections provide a comprehensive list of BitLocker Group Policy settings that are organized by usage. BitLocker Group Policy settings include settings for specific drive types operating system drives, fixed data drives, and removable data drives and settings that are applied to all drives. The following policy settings can be used to determine how a BitLocker-protected drive can be unlocked.
The following policy settings are used to control how users can access drives and how they can use BitLocker on their computers. The following policy settings determine the encryption methods and encryption types that are used with BitLocker. The following policy settings define the recovery methods that can be used to restore access to a BitLocker-protected drive if an authentication method fails or is unable to be used.
The options of the Require additional authentication at startup policy apply. The preboot authentication option Require startup PIN with TPM of the Require additional authentication at startup policy is often enabled to help ensure security for older devices that do not support Modern Standby. But visually impaired users have no audible way to know when to enter a PIN.
Enable BitLocker on Windows 10
This setting enables an exception to the PIN-required policy on secure hardware. This policy controls a portion of the behavior of the Network Unlock feature in BitLocker.There are a few options under there that you could use to force Bitlocker on For removable drives there is Deny write access to removable drive not protected by Bitlocker.
I'm trying to avoid the step of a tech having to touch the machine or an end-user having to enable the encryption. Have you tried creating a scheduled task with Group Policy Preferences and calling manage-bde.
I recently ran into the same dilemma as others and successfully started BitLocker encryption with the following scheduled task settings in Group Policy Computer Configuration - Preferences - Control Panel Settings - Scheduled Task :. You may have other unique constraints for your specific environment and might require some PowerShell or batch file scripting, but the above worked well on our computers in conjunction with a separate GPO of our desired BitLocker parameters, Disclaimer: I did need to reboot the PC for encryption to start, but that could be part of a scheduled task as well.
It also wrote the recovery information as desired to Active Directory. First, and perhaps the easiest, is simply linking the GPO to the OU where the computer s reside depending on your directory structure. However, you more than likely need to control applicability of the GPO which leads to the next choice.
Since we are using Computer Configuration instead of User Configuration settings, you can create an AD group with the computer accounts that you would like to apply the policy. As an example assuming your AD group with computer accounts is "Bitlocker Computers" :.
My least preferred but still possible option is selecting individual computers instead of the group in option 2. Thank you for your help on this. I'm trying to create scheduled task gpo same way you mentioned but not sure how should I schedule it.

By using PowerShell for this task we can deploy it to multiple machines at ones and in the meantime store the recover password in the Active Directory.
With the use of te BitLocker Windows Powershell cmdlets we can, for example, encrypt the operating system volumes and set different protectors.
Just encrypting the used space is enough. When new data is added, it will be encrypted immediately. The command below will encrypt the used space only, skip the hardware test and store the recovery password in the Active Directory. To do so, we first need to convert the pin to a secure string:.
Включение или отключение BitLocker с модулем TPM в Windows
Hi, when I try to store the recovery key on a specified path, the file is not created. So I can disable BitLocker just like that. Do you know how I can fix this? Thank you. Should this work remotely through an invoke-command or remotely from an enter-pssession to the workstation?
Rudy, does my domain functional level need to be at a certain level for this to store recovery passwords for W10 machines in AD?
If you are running Windows or newer you should be fine. If you are still onthen you need to extend the schema to store the info.Finding a lost Bitlocker Recovery Key

Before any comments of network outage preventing users from booting - users in this situation are relying on network availability and should not use a machine if it's not networked business location requirement.
If you can use Windows 8, the Network Unlock feature sounds like what you're looking for. In the event the computer wasn't on the proper network, the user would be prompted for the PIN that they wouldn't have to boot the computer. We are planning to implement BitLocker in our company. Your article is my tutorial. In my company most of the laptops does not have TPM. In that case, is there anything i should follow which might not mentioned in this article?

This feature can be enabled or disabled based on your preferences by tweaking the Local group policy Editor.
The enforcement of drive encryption type policy settings allows you to specify the encryption time used by Bitlocker. In order to have the policy come into effect, the bitlocker encryption should be turned on.
Changing the encryption type has no effect if the drive is already encrypted or on progress on going. If you enable this policy setting, then the computer will not ask for the encryption type and will use an encryption time exclusively defined by the user from the options provided by policy settings. Again, If you disable or do not configure this policy setting, the BitLocker setup wizard will ask the user to select the encryption type before turning on BitLocker.
Choose full encryption to require that the entire drive be encrypted when BitLocker is turned on. Choose used space only encryption to require that only the portion of the drive used to store data is encrypted when BitLocker is turned on. Type gpedit. In the right panel, select Enforce drive encryption type on fixed data drives.
Double click on the policy setting to edit it. If you do not want Bitlocker to ask for encryption type, then click on Enabled. Click on Apply and then OK. If you want Bitlocker to ask for the encryption type, then select Disabled. Save my name, email, and website in this browser for the next time I comment. This site uses Akismet to reduce spam.
