Full Disk Encryption (FDE): A security measure used to protect all data on a hard drive. By encrypting every bit of data, including files, folders, and the operating system itself, FDE renders the stored information unreadable to unauthorized individuals. This measure is particularly useful if a device gets lost or stolen, as it prevents unauthorized access to the data, ensuring only those with the correct decryption key or password can access the information.
