Certified Incident Handler (CIH) Practice Ecam

Which tool is necessary for obtaining a clean copy of a device for forensic analysis?

1. Wireshark

2. Imagine tool

3. Fiddler

4. Snort

The correct answer is: Imagine tool

The selection of the imaging tool for forensic analysis is essential because it allows investigators to create a bit-by-bit copy of a device's storage, preserving the original data intact. This process is critical in forensic investigations as it ensures that all data, including deleted or hidden files, can be examined without altering the original evidence. The imaging tool effectively captures the entire disk image, which contains not just files and folders but also system metadata and unallocated space. In contrast, tools like Wireshark, Fiddler, and Snort are designed for different purposes. Wireshark is primarily a network protocol analyzer, used for capturing and analyzing network traffic in real-time. Fiddler operates as a web debugging proxy, allowing inspection of HTTP and HTTPS traffic but not creating device images. Snort is an intrusion detection and prevention system focused on analyzing network traffic for suspicious patterns or malware. These tools are valuable in their respective domains but do not serve the specific need for creating forensic copies of devices. Therefore, the imaging tool stands out as necessary for obtaining a clean, reliable copy of a device for thorough forensic analysis.
