Which of the following best describes drive imaging in the context of digital forensics?

Drive imaging in digital forensics refers to the technique used to create an exact copy of a data source, such as a hard drive or SSD. This process involves capturing all data, including the operating system, installed programs, and files, in a bit-for-bit representation. The purpose of drive imaging is to preserve the integrity of the original data while allowing forensic analysts to conduct investigations without altering the source, thereby maintaining a chain of custody and ensuring the evidence is admissible in court.

Creating an exact copy means that the resulting image is identical to the original, capturing not only the user files but also any hidden data and system information that may be important for an investigation. This meticulous replication is critical when examining potential evidence, as even minor changes to the data during analysis could compromise the investigation's validity.

In contrast, other choices describe different processes—data deletion, efficient backup methods, and remote file viewing—which do not align with the core purpose and function of drive imaging within digital forensics.
