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.
