Why is it not recommended for a small firm to conduct its own breach investigation instead of hiring professionals?

• A. Searching for evidence themselves would not have any ill effects
• B. Searching could possibly crash the machine or device
• C. Searching creates cache files, which would hinder the investigation
• D. Searching can change date/time stamps

Answer: (D)

Preserving the integrity of digital evidence is essential in a breach investigation. Any interaction with a breached system can change data, and the date/time stamps on files and logs are particularly sensitive pieces of evidence. When you search, copy, or view files on a live system, you may perform write operations or trigger system processes that update these timestamps, alter metadata, or modify logs. Once timestamps are altered, the sequence of events becomes unreliable, which can mislead investigators and jeopardize the admissibility of findings in legal or formal review. That's why professionals use proper forensic tools, write blockers, and documented procedures to image the system and preserve a clean chain of custody, ensuring evidence remains unchanged from collection through analysis. For a small firm, attempting an in-house breach investigation increases the risk of unintentionally changing timestamps and other critical artifacts, undermining the investigation’s usefulness and credibility.
