問題 #16
Alice and John are close college friends. Alice frequently sends emails to John attaching her pics with friends.
One day, Alice sent an email to John describing all the details related to the final year project without specifying the actual purpose. John missed the message as he frequently receives emails from her and did not arrive for a project seminar.
Which of the following email fields could Alice have used in the above scenario to highlight the importance of the email?

答案：C

解題說明：
TheSubjectfield is the primary email header element used to communicate thepurpose and urgencyof a message at a glance. Digital forensics training emphasizes that email messages consist ofheaders(routing and descriptive metadata) and abody(content). Among user-visible header fields, the Subject line is specifically intended to summarize what the email is about, helping recipients prioritize and correctly interpret the message without opening it. In the scenario, John routinely receives casual emails from Alice (often with pictures). When Alice sent a project-related email "without specifying the actual purpose," John treated it like routine mail and overlooked its significance. A clear, descriptive subject such as "Final Year Project Seminar
- Attendance Required" would have flagged the message as time-sensitive and different from her usual emails, reducing the chance it would be missed.
The other options do not serve this purpose.Dateis automatically assigned and mainly supports ordering and timeline reconstruction rather than highlighting importance.CcandBcccontrol who receives copies and can affect visibility or secrecy, but they do not summarize intent for the recipient. Therefore, the field best suited to highlight importance isSubject (A).


問題 #17
John, a forensic officer, was working on a criminal case. He employed imaging software to create a copy of data from the suspect device on a storage medium for further investigation. For developing an image of the original data, John used a software application that does not allow an unauthorized user to alter the image content on storage media, thereby retaining an unaltered image copy.
Identify the data acquisition step performed by John in the above scenario.

答案：D

解題說明：
The scenario emphasizes that John used an application (or mechanism) thatprevents alteration of the acquired image content, ensuring the image remainsunalteredand protected from unauthorized modification. In forensic acquisition standards, this corresponds toenabling write protectionduring imaging-commonly implemented using awrite blocker(hardware or controlled software write-protection) to prevent any writes to the source evidence and, where applicable, to protect the integrity of the evidence copy from accidental or unauthorized changes. The purpose is to preserve evidential integrity by ensuring that neither the original media nor the forensic image is modified during handling, analysis preparation, or transfer.
"Validated data acquisition" refers to confirming the image is an exact duplicate, typically by computing and comparing cryptographic hashes (e.g., MD5/SHA) of the source and the acquired image. While validation is essential, the question specifically highlightspreventing alteration, not verifying equality. "Sanitized the target media" is the step of wiping/clearing the destination drive before acquisition to avoid contamination, which is not what is described. "Planned for contingency" relates to operational planning for unexpected issues (equipment failure, encryption, power loss), not integrity protection. Therefore, the best match isEnabled write protection on the evidence media (A).
