Forensic Image
Noun · Security & Infosec
Definitions
A bit-for-bit copy of a storage device created in a way that preserves evidence and supports later verification, usually with hashing and careful documentation. A forensic image captures deleted space, slack space, and metadata that normal file copies miss.
In plain English: An exact evidence-grade copy of a storage device.
Example: "Before touching the drive, the team created a forensic image and recorded the hash values."
