True or false:
Bitlocker is available for Microsoft Windows while EFS is a comparable disk encryption solution for Linux and Mac
True
False
Both Bitlocker and Encrypting File System (EFS) are solutions available to Microsoft Windows operating systems. Bitlocker encrypts an entire disk while EFS is a file-level encryption technology.
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS that provides filesystem-level encryption. The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer. EFS is available in all versions of Windows except the home versions (see Supported operating systems below) from Windows 2000 onwards. By default, no files are encrypted, but encryption can be enabled by users on a per-file, per-directory, or per-drive basis. Some EFS settings can also be mandated via Group Policy in Windows domain environments.Cryptographic file system implementations for other operating systems are available, but the Microsoft EFS is not compatible with any of them.
