10+ practice questions focused on Computer Forensics Investigation 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 Investigation Process PracticeDuring a forensic investigation, an analyst discovers that the suspect's hard drive was encrypted using BitLocker. The analyst has obtained the recovery key. Which of the following is the best next step to ensure data integrity?
Explanation: Option C is correct because creating a forensic image of the encrypted drive before decryption preserves the original evidence in its pristine, unaltered state. Decrypting the image later using the recovery key ensures that the original encrypted data remains intact and verifiable, maintaining data integrity throughout the investigation.
A CHFI analyst is called to investigate a suspected data breach. The IT team has already shut down the server. Which of the following is the most appropriate order of actions to preserve evidence?
Explanation: Option D is correct because it follows the established forensic investigation process: secure the scene to prevent contamination, document the state of the server (photographs and connection diagrams), then physically remove the hard drives and create forensic images using a write-blocker to preserve the original data without alteration. This ensures evidence integrity and admissibility in legal proceedings.
An incident responder has acquired a forensic image of a Linux server suspected of being compromised. The image was taken using 'dd' with no compression. The analyst needs to verify the integrity of the image. Which command should be used and what should be compared?
Explanation: Option D is correct because the SHA-256 hash computed during acquisition from the source device provides a cryptographic integrity check. By recomputing the hash on the acquired image and comparing it to the original hash, the analyst can verify that the image is an exact bit-for-bit copy without any alteration or corruption. SHA-256 is preferred over MD5 in forensic contexts due to its stronger collision resistance.
Which TWO of the following are considered essential steps in the computer forensics investigation process according to EC-Council guidelines?
Explanation: Identification of potential evidence is a core initial step in the EC-Council's computer forensics investigation process because it defines the scope and sources of data that may contain relevant evidence. Without proper identification, investigators risk missing critical data or collecting irrelevant information, which can compromise the entire investigation. This step involves recognizing potential evidence sources such as hard drives, network logs, and volatile memory, ensuring that all relevant data is accounted for before collection begins.
An analyst executed the commands shown in the exhibit on a Windows system to prepare a forensic image for analysis. What is the most likely reason for the error message from e2fsck?
Explanation: The error message from e2fsck indicates that the filesystem has inconsistencies, which typically occur when a volume is imaged while it is still mounted and actively being written to. The analyst likely did not dismount the source volume before acquiring the forensic image, resulting in a snapshot that reflects an inconsistent state (e.g., dirty journal, unflushed writes). This is a common chain-of-custody and acquisition procedure error in forensic imaging.
