BitLocker is an encryption technology built into Windows operating systems. Kaspersky Endpoint Security allows you to control and manage Bitlocker using Kaspersky Security Center. BitLocker encrypts logical volumes. BitLocker cannot be used for encryption of removable drives. For more details on BitLocker, refer to Microsoft documentation.
BitLocker provides secure storage of access keys using a trusted platform module. A Trusted Platform Module (TPM) is a microchip developed to provide basic functions related to security (for example, to store encryption keys). A Trusted Platform Module is usually installed on the computer motherboard and interacts with all other system components via the hardware bus. Using TPM is the safest way to store BitLocker access keys, since TPM provides pre-startup system integrity verification. You can still encrypt drives on a computer without a TPM. In this case, the access key will be encrypted with a password. BitLocker uses the following authentication methods:
After encrypting a drive, BitLocker creates a master key. Kaspersky Endpoint Security sends the master key to Kaspersky Security Center so that you can restore access to the disk, for example, if a user has forgotten the password.
If a user encrypts a disk using BitLocker, Kaspersky Endpoint Security will send information about disk encryption to Kaspersky Security Center. However, Kaspersky Endpoint Security will not send the master key to Kaspersky Security Center, so it will be impossible to restore access to the disk using Kaspersky Security Center. For BitLocker to work correctly with Kaspersky Security Center, decrypt the drive and re-encrypt the drive using a policy. You can decrypt a drive locally or using a policy.
After encrypting the system hard drive, the user needs to go through BitLocker authentication to boot the operating system. After the authentication procedure, BitLocker will allow for users to log in. BitLocker does not support single sign-on technology (SSO).
If you are using Windows group policies, turn off BitLocker management in the policy settings. Windows policy settings may conflict with Kaspersky Endpoint Security policy settings. When encrypting a drive, errors may occur.
