You need to secure the contents of your entire hard disk drive even if an unauthorized user steals your computer. Which method should you use?

Rights Management Services protects individual files or documents by applying usage restrictions, not the entire hard drive.

File-level share permissions control network access to shared folders and files, not the physical security of data on a stolen drive.

Password-protection typically refers to login passwords, which can be bypassed by booting from another device or removing the drive.

BitLocker encryption provides full disk encryption, encrypting the entire volume and ensuring that data is unreadable without the correct decryption key, even if the drive is removed from the stolen computer. This prevents unauthorized access to the drive's contents at rest.
