![]() As such, the password option is discouraged and disabled by defaultīoth options don't provide the preboot system integrity verification offered by BitLocker with a TPM. This option isn't secure since it's subject to brute force attacks as there isn't a password lockout logic. use a startup key, which is a file stored on a removable drive that is used to start the device, or when resuming from hibernation.This implementation requires the user to either: ![]() On devices that don't have a TPM, BitLocker can still be used to encrypt the operating system drive. These security measures provide multifactor authentication and assurance that the device can't start or resume from hibernation until the correct PIN or startup key is presented. In addition to the TPM, BitLocker can lock the normal startup process until the user supplies a personal identification number (PIN) or inserts a removable device that contains a startup key. ![]() The TPM works with BitLocker to ensure that a device hasn't been tampered with while the system is offline. BitLocker and TPMīitLocker provides maximum protection when used with a Trusted Platform Module (TPM), which is a common hardware component installed on Windows devices. BitLocker helps mitigate unauthorized data access by enhancing file and system protections, rendering data inaccessible when BitLocker-protected devices are decommissioned or recycled. Practical applicationsĭata on a lost or stolen device is vulnerable to unauthorized access, either by running a software-attack tool against it, or by transferring the device's hard drive to a different device. BitLocker is a Windows security feature that provides encryption for entire volumes, addressing the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned devices.
