What is BitLocker?
Windows BitLocker Drive Encryption is a new security feature in Windows Vista and later that protects files on your computer in the event that anyone tampers with the computer's startup process. BitLocker can leverage the Trusted Platform Module (TPM) security hardware to guard data and system files in the Windows operating system directory, and also protects early boot component integrity. Encrypting the entire Windows volume with BitLocker can help prevent others from seeing your files, even if your computer is stolen or a hard disk removed. At Indiana University, BitLocker may provide a useful tool for meeting the requirements for protecting confidential data described in Protecting Data.
