Computer Hacking Forensic Investigator (CHFI) Practice Exam

FTK Imager is a widely recognized tool specifically designed for forensic data acquisition. Its primary function is to create disk images and perform data extraction in a manner that maintains the integrity of the original data, which is crucial in forensic investigations. This tool allows forensic investigators to obtain a bit-for-bit copy of storage devices, ensuring that all data—deleted files, hidden data, and unallocated space—is captured for analysis without altering the original evidence.

In contrast, while tools like Wireshark, Metasploit, and Nmap serve important functions in the realm of cybersecurity, they are not primarily focused on forensic data acquisition. Wireshark is mainly used for network traffic analysis, capturing and dissecting data packets. Metasploit is a penetration testing framework that is used for developing and executing exploit code against remote targets. Nmap is a network scanning tool used for discovering hosts and services on a computer network by sending packets and analyzing the responses. None of these tools offer the same specialized capabilities for creating forensic images of storage media, making FTK Imager the clear choice for this purpose.
