What does "forensic imaging" entail?

Forensic imaging refers specifically to the process of creating an exact, bit-by-bit copy of a storage device. This approach ensures that every bit of data, including deleted files, file system information, and residual data, is captured in a manner that preserves its integrity and evidential value. The importance of this practice lies in its ability to allow forensic analysts to work with an exact duplicate of the original data without altering or damaging the original evidence. Therefore, forensic imaging is crucial in legal contexts, where maintaining the authenticity and provenance of evidence is vital.

Capturing live data or recovering deleted files, while related to digital forensics, do not encompass the complete scope of forensic imaging. Additionally, real-time analysis of network traffic pertains to a different aspect of cybersecurity and digital forensics focused on monitoring and analyzing data flows rather than creating a complete replica of a storage device. Thus, the emphasis on creating a bit-by-bit copy distinguishes forensic imaging as a foundational technique in digital forensics.
