Which of the following is a common method for data acquisition in digital forensics?

Disk imaging is a common method for data acquisition in digital forensics because it creates an exact byte-for-byte copy of a storage device. This reflection of the original data ensures that the forensic expert has a complete and unaltered copy of the evidence, preserving the integrity for analysis while allowing the original device to remain untouched. This method captures all files, including hidden files, deleted files, and metadata, which are crucial for thorough forensic investigations.

The process also facilitates repeat analyses, allowing investigators to work on the image rather than the original device, thereby preventing accidental alteration of the evidence. By ensuring data integrity, disk imaging stands as a cornerstone methodology in digital forensic practices, adhering to legal standards and best practices for evidence handling.
