In a computer forensics investigation, what describes the route that evidence takes from the time you find it until the case is closed or goes to court?

• A. Chain of custody
• B. Evidence lifecycle
• C. Forensic analysis workflow
• D. Case file progression

Answer: (A)

Tracking the movement and handling of evidence from discovery to disposition is the chain of custody. This is the documented, chronological record of where the evidence came from, who handled it, when it was transferred or accessed, how it was stored, and what was done to it throughout the life of the case. The key point is preserving the integrity of the evidence by showing it remained unaltered and authentic from collection through analysis to court. Practices like maintaining tamper-evident seals, logging access, using write blockers, hashing files, and secure storage all contribute to a verifiable path that the evidence followed, which is essential for admissibility in court. The other options don’t describe this path as precisely. The evidence lifecycle covers stages from creation to disposal but doesn’t focus on who handled the item and how it moved between locations. The forensic analysis workflow outlines steps for conducting the technical analysis itself, not the custody and transfer history. The case file progression is about documenting the case’s status and progress, not the actual evidence’s chain of custody.
