BitLocker Drive Encryption

The BitLocker Drive Encryption can be used to Encrypt Data that is stored on the System Drive or other mass storage.
The encryption of the Data Drive is especially recommended for mobile end devices, since they are vulnerable to theft or beeing lost.
In those cases the Drive Encryption can be the last provision to prevent unauthorized access to the data.

Requirements

Domain membership

Before you can start with the implementation of an BitLocker encryption you need to check if the computersystem is part of the NWZ domain.
To do so, use the Powershell command
wmic computersystem get domain
If the console doesnt return
nwz.wwu.de
then the computer is not part of the domain.

Trusted Platform Module Informations

For an efficient encryption the computersystem should be equipt with an TPM in the Version 2.0.
To check if the system is equipt with an TPM you can use the Powershell command
tpm.smc

TPM Informations under Windows 10

The "Trusted Platform Module"-Management console offers informations about the installed module of the computer.
The TPM version can be seen under the producer informations.
Should the console not be able to provide Informations, then there is no TPM installed or the system is not able to communicate with the module.

Implementation

Include Group Policy Object

In order for the computersystem to receive the necessery informations about the encryption the Group Policy Object (GPO) for the BitLocker encryption has to be associated with the organisational unit (OU) of the computer object.
The GPO can be associated with an OU in the Pre Stagging Console.
After the implementation of the GPO the computer needs to be restarted for the changes to take effect.

Initialize the Encryption

To start the encryption process you need to login with your administration account.
Open the system settings and choose the BitLocker Drive Encryption.
Here you can see the encryption settings for all drives.
Choose activate system Drive BitLocker Encryption.
Follow the wizard for the BitLocker Drive Encryption.

To initialize the BitLocker Drive Encryption the computer needs to be restarted.
Once the computer reboots, you will be prompted with the BitLocker Drive Encryption.
Input the password that you set during the initialization.

BitLocker Recovery Informations

Review the BitLocker Recovery Informations

The recovery informations that are needed if the password for the drive has been lost are stored within the computer object in the Active Directory.

To receive these informations please start the Pre-Stagging Console that can be accessed within Citrix.
Navigate the the Organisational Unit (OU) where the affected computer object is located.
