EFS
(Encrypting File System)
Encrypting File System (EFS) is a feature in Windows operating systems that enables users to encrypt files and folders to protect sensitive data from unauthorized access. EFS uses symmetric key encryption combined with public key cryptography to secure data at rest.
EFS is particularly useful for protecting data on shared systems or portable devices, such as laptops. It integrates seamlessly with the Windows file system, allowing users to encrypt files with a few clicks. While EFS provides strong encryption, it is important to back up encryption keys to avoid data loss. EFS is often compared to other encryption solutions like BitLocker, which offers full-disk encryption.
