CISM · Question #537
An incident handler is preparing a forensic image of a hard drive. Which of the following MUST be done to provide evidence that the image is an exact copy of the original?
The correct answer is D. Perform digital hashing of the original and the image. Computing and comparing cryptographic hashes (e.g., MD5, SHA-1) of the original drive and the forensic image provides verifiable proof that every bit was copied exactly, ensuring integrity.
