ACE Legal, Ethical & Reporting Standards 3 — Questions and Answers
Question 1: Under what circumstances may a private employer legally search an employee's company-issued computer without a warrant?
- Never; employees have absolute Fourth Amendment rights
- Only with written consent signed before employment
- Generally always, because employees have a reduced expectation of privacy on employer-owned devices (Correct answer)
- Only when a crime has already been reported to police
Correct answer: Generally always, because employees have a reduced expectation of privacy on employer-owned devices
Employees typically have a reduced expectation of privacy on employer-owned equipment, especially when usage policies notify them of monitoring.
Question 2: What is the primary purpose of maintaining a detailed chain of custody log for digital evidence?
- To satisfy IRS audit requirements for forensic service fees
- To document every person who accessed the evidence and when, ensuring integrity and admissibility (Correct answer)
- To track software license usage during the investigation
- To comply with HIPAA data handling requirements
Correct answer: To document every person who accessed the evidence and when, ensuring integrity and admissibility
Chain of custody documentation ensures that evidence integrity can be verified and that admissibility challenges related to tampering can be defended.
Question 3: The Computer Fraud and Abuse Act (CFAA) defines 'unauthorized access' as:
- Any access to a computer without physical presence at the device
- Accessing a computer without permission or exceeding authorized access (Correct answer)
- Using another person's login credentials regardless of permission
- Accessing encrypted files without a decryption key
Correct answer: Accessing a computer without permission or exceeding authorized access
The CFAA prohibits intentionally accessing a computer without authorization or in excess of authorized access.
Question 4: In a forensic examination report, an 'opinion section' should clearly distinguish that the content represents:
- Absolute facts verified by the court
- The examiner's expert interpretation based on observed evidence (Correct answer)
- Statements made by the suspect during interview
- Instructions from the retaining attorney
Correct answer: The examiner's expert interpretation based on observed evidence
Opinion sections must be labeled as expert interpretation to separate factual findings from analytical conclusions.
Question 5: When an ACE examiner testifies as an expert witness, their primary duty is to:
- Advocate for the party that retained them
- Present only evidence favorable to the defense
- Provide truthful, impartial testimony based on their findings (Correct answer)
- Repeat the retaining attorney's narrative
Correct answer: Provide truthful, impartial testimony based on their findings
Expert witnesses owe their primary duty to the court, not to the retaining party—testimony must be truthful and impartial.
Question 6: A forensic examiner receives a subpoena for case files while the case is under a protective order. The correct response is to:
- Comply immediately with the subpoena and release all files
- Ignore the subpoena because the protective order supersedes it
- Notify the retaining attorney and seek legal guidance before disclosing protected materials (Correct answer)
- Destroy the files to prevent unauthorized disclosure
Correct answer: Notify the retaining attorney and seek legal guidance before disclosing protected materials
Conflicting legal obligations require legal counsel's guidance; releasing protected materials without proper motion may violate the protective order.
Question 7: International digital investigations are complicated primarily because:
- Foreign courts always require Spanish translation of reports
- Data privacy laws and mutual legal assistance treaty (MLAT) requirements vary by country (Correct answer)
- U.S. forensic certifications are not recognized abroad
- Time zone differences prevent real-time evidence collection
Correct answer: Data privacy laws and mutual legal assistance treaty (MLAT) requirements vary by country
Different nations have distinct data privacy laws and evidence collection requirements; MLATs govern how countries share evidence across borders.
