It also enables other device related features like Windows Hello for Business. In this way, users can use a single identity to access on-premises applications and cloud services. Azure AD ConnectĪzure AD Connect is a service which is aimed to keep the association between the computer and user accounts in your on-premises Active Directory (AD) and the device and user objects in Azure AD. For this scenario, AAD Premium is needed. Azure AD comes in three editions: Free, Basic, and Premium. It helps secure access to on-premises and cloud applications. Īzure Active Directory (AAD) is a comprehensive identity and access management cloud solution that provides a robust set of capabilities to manage users and groups. The system automatically decrypts the drive at boot up. When this is used, no information is required on the part of the user.

  • Finally, the TPM may be used to protect the FVEK.
  • This is a must, for data recovery in an emergency.

    A Recovery Key can be created and stored in Active Directory and\or in Azure Active Directory.When this is in place as a key protector, the end user must supply the passcode at each boot. A passcode (whether short or long, numerical, alphabetical, or alphanumerical) could be used as a protector.

    When this is done, that flash drive must be plugged into the pc at boot up in order to unlock the drive and boot the system.

  • A USB drive could be configured as a so-called “key protector”.
  • Knowledge of the VMK and FVEK is not necessary for BitLocker implementation, but knowledge of the key protectors is required Key ProtectorsĪ key protector is yet another key that protects the VMK, which in turn protects the FVEK, which in turn protects the data. The VMK itself is further encrypted by “Key Protectors”. This is automatically generated and managed by BitLocker The “Volume Master Key” unlocks the FVEK, which in turn decrypts the C: drive.

    The FVEK is stored in metadata which itself is encrypt by the VMK, explained below VMK The “Full Volume Encryption Key” is a key used by BitLocker to encrypt the entire C: drive. With TPM & BitLocker, the system would automatically decrypt the PC on startup, without requiring the use of a pin, usb, or other form of authentication FVEK It provides a way of creating and encrypting keys that could be used for BitLocker and for other security related features. The “Trusted Protection Module” is a microchip that comes built-into most laptops and desktops ordered today. Basic Conceptsīefore moving further, there are a few terms you need to be familiar with: TPM Instead, the goal is to provide “better than nothing” encryption, which is far superior to leaving the disks in clear text. With all of that said, this form of implementation is not the most secure available, since, for example, it won’t allow for multi-factor authentication. Note that in this article, only TPM recovery key is covered, meaning that only the OS volume is managed, without PIN codes to remember, no usb key required at logon, 100% transparent as far as users are concerned! In order to ease the manageability effort required by BitLocker, we want to leverage a traditional System Management platform, such as System Center Configuration Manager, as well as the IDaaS (Identity as a service) feature offered by Azure Active Directory and the automation capabilities provided by Azure Automation, so as to allow the end-user to recover the BitLocker key protector by accessing the portal. 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, drive encryption is an integral part of good 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. This can be done by simply docking the system’s HDD onto another computer to browse the file system or by running a live distro of Linux\WinPE where the data would be in clear text. With traditionally un encrypted disks (the vast majority of the world’s computers), attackers could extract all of the data available on the local disk.

    WHAT IS A BITLOCKER FREE

    BitLocker is a free encryption feature in Windows that comes standard on most versions of the OS and allows for the encryption of drives on the system, as a layer of security.
