After examining a header and footer file, a security analyst begins reconstructing files by scanning the raw data bytes of a hard disk and rebuilding them. Which of the following techniques is the…

Header analysis is a component of file carving, involving the identification of the start of a file, but it does not encompass the entire process of scanning raw data and rebuilding the complete file.

File carving is a digital forensics technique used to recover files from raw data on a storage medium, even when file system metadata is damaged or missing. It works by scanning the raw data for known file headers, footers, or other file-specific signatures to identify and reconstruct the boundaries of individual files.

Metadata analysis involves examining information *about* files, such as creation dates, modification times, and permissions, rather than reconstructing the actual file content from raw data bytes.

Data recovery is a broader term that encompasses various methods to restore lost or corrupted data, while file carving is a specific technique within data recovery that focuses on reconstructing files from raw data using header and footer recognition.
