Computer Hacking Forensic Investigator (CHFI) v11 Practice Test 2026 - Free CHFI Practice Questions and Study Guide

Tracking digital evidence requires a clear, auditable record of every transfer and handling to preserve integrity and admissibility in court. The document that captures every handoff, with timestamps, signatures, and often digital hashes, is the chain of custody form. It records who collected the evidence, who has held it, where it was stored, and how it was transferred or analyzed, creating an unbroken trail from collection to presentation. This ensures that if the evidence is challenged, there is verifiable provenance showing it was not altered or tampered with. The other forms don’t serve this purpose: an evidence collection form records the initial collection details but not the ongoing custody and transfers; a search warrant form is the legal authorization for seizure rather than a record of custody; an expert witness form relates to someone’s qualifications or role, not the custody trail.
