Which sequence best describes the key stages of the digital evidence lifecycle in forensics?

• A. Collection, Identification, Preservation, Analysis, Interpretation, Documentation, and Presentation.
• B. Preservation, Identification, Collection, Analysis, Documentation, Presentation, and Interpretation.
• C. Collection, Identification, Preservation, Analysis, Interpretation, Documentation, and Presentation.
• D. Identification, Preservation, Collection, Analysis, Interpretation, Documentation, and Presentation.

Answer: (D)

The sequence begins by identifying what data may be relevant, which sets the scope and prevents chasing unnecessary artifacts. Once identified, preservation is done to keep the data in its original state and protect its integrity (often using write blockers and hash verification) before any touching of the evidence. After preservation comes collection, where forensic copies are obtained in a manner that maintains a solid chain of custody. With the data collected, analysis is performed to extract artifacts and uncover what happened. Interpretation then translates those findings into meaning about the case, such as timelines or actions taken by users. Documentation records every step, tool, hash, and decision to ensure the process is traceable and reproducible. Finally, presentation communicates the results clearly to stakeholders, usually in a formal report or testimony, including any uncertainties or limitations.
