What feature does BitLocker specifically support?

BitLocker specifically supports full disk encryption, including the operating system. This means that it encrypts the entire volume, which not only secures personal files but also protects the operating system files from unauthorized access. By doing so, BitLocker helps to safeguard data against theft or exposure when a device is lost or stolen. The encryption occurs at the disk level, ensuring that all data on the protected drive remains secure, making it a comprehensive solution for data protection.

In contrast, file-level encryption is limited to specific files or folders, which does not provide the same level of security for the entire operating system or drive. Remote backup solutions involve storing data offsite but do not encrypt the drive itself, and identity protection management typically refers to features that help secure against identity theft, rather than providing encryption for data storage.
