Which type of encryption occurs at a filesystem level in combination with a cryptographic algorithm?

File-level encryption
Full-disk encryption
Database encryption
Network encryption

The correct answer is: File-level encryption

File-level encryption is designed to secure individual files or sets of data on a filesystem rather than encrypting the entire disk or volume. This encryption operates at the filesystem level, meaning it specifically targets files, directories, or individual data elements. By utilizing cryptographic algorithms, file-level encryption ensures that only users with the appropriate decryption keys can access the encrypted data, providing a layer of security for sensitive information stored on the device. In contrast to full-disk encryption, which encrypts everything on the disk and is often transparent to the user, file-level encryption allows for more granularity, enabling users to decide which files to encrypt based on their sensitivity. While database encryption focuses specifically on the protection of data within a database, and network encryption secures data in transit over networks, these are distinct from the targeted approach of file-level encryption, which is directly tied to the files themselves at the filesystem layer.
