Which aspect of BitLocker relates to the protection of local drives?

The aspect of BitLocker that relates to the protection of local drives is pre-start system integrity verification. BitLocker is a disk encryption program included with certain versions of Microsoft Windows, designed to protect data by providing encryption for entire volumes. The pre-start system integrity verification process occurs during the boot phase of the system and ensures that the system has not been tampered with before the operating system is loaded. This verification helps prevent unauthorized access to the drive, ensuring that only a trusted operating system can decrypt and access the data on the local drive.

The integrity checks happen through a mechanism known as the Trusted Platform Module (TPM), which stores encryption keys and ensures that if any changes are detected in the pre-boot environment (such as a change in BIOS or bootloader), BitLocker will halt the boot process and require the recovery key for access. This provides a strong layer of security for local drives by safeguarding against various types of attacks, such as pre-boot exploits or unauthorized modifications.

In contrast, folder-level encryption focuses on specific files or folders rather than entire drives; device authentication verifies the identity of the device, and network file sharing pertains to sharing files over a network rather than securing local drives. Thus, pre-start system integrity verification is key to ensuring
