20+ practice questions focused on Computer Forensics Fundamentals and Process — one of the most tested topics on the Computer Hacking Forensic Investigator CHFI exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Computer Forensics Fundamentals and Process PracticeA first responder arrives at a crime scene where a computer is running. According to standard forensic procedure, what should the responder do FIRST?
Explanation: The first priority at a live crime scene is to preserve the integrity of the scene and all potential evidence. Standard forensic procedure (e.g., from NIST SP 800-86 and ACPO guidelines) mandates that the first responder must photograph the scene to document the state of the computer (including screen contents, cables, and peripherals) and secure the area to prevent unauthorized access or tampering. Only after this documentation and scene stabilization can the responder proceed to handle the live system, such as capturing volatile data or creating a forensic image.
During a forensic investigation, an analyst uses a hardware write blocker to connect a suspect hard drive to a forensic workstation. What is the primary purpose of using a hardware write blocker?
Explanation: A hardware write blocker physically intercepts the write commands from the forensic workstation to the suspect drive, ensuring that no data can be altered on the source drive during acquisition. This preserves the evidentiary integrity of the original media, which is a foundational requirement in digital forensics to maintain a chain of custody and admissibility in court.
A forensic investigator is preparing to acquire the contents of a live system's RAM. Which of the following tools is specifically designed for this purpose and captures memory without altering the system state?
Explanation: FTK Imager is specifically designed for live memory acquisition on Windows systems, capturing RAM contents via a kernel-level driver (e.g., win32dd or FTK Imager's own memory capture module) that reads physical memory without modifying the system state. It creates a forensic image (e.g., .mem or .raw) while maintaining data integrity through hashing (MD5/SHA1). This makes it the correct choice for acquiring RAM from a live system without altering evidence.
During a forensic investigation, an analyst creates a forensic image using `dcfldd` with the command: `dcfldd if=/dev/sda of=image.dd hash=sha256 hashwindow=10M`. What is the purpose of the `hashwindow` parameter?
Explanation: The `hashwindow` parameter in `dcfldd` specifies the size of the data chunks for which individual hash values are computed. With `hashwindow=10M`, the tool generates a SHA-256 hash for every 10 MB block of the input data, allowing verification of integrity on a per-block basis rather than only a single hash for the entire image. This is useful for detecting corruption or tampering in specific segments of large forensic images.
A forensic analyst is examining a hard drive that was seized from a suspect's home. The analyst uses FTK Imager to create a forensic image. After imaging, the analyst computes the MD5 hash of the image and compares it to the hash computed at the scene. The hashes match. What does this confirm?
Explanation: B is correct because a matching MD5 hash between the image and the original drive confirms that the forensic image is an exact bit-for-bit copy. Hashing algorithms like MD5 produce a unique fixed-size hash value based on the binary content; if two hashes match, the data is identical with no alterations. This validates the integrity of the acquisition process, ensuring that the image is a perfect forensic duplicate.
