A cybersecurity analyst is tasked with creating a forensic image of a hard drive from a compromised system. To ensure the original evidence is not altered during the acquisition process, which of the following tools is MOST essential?
Chain-of-custody form
Hashing utility
Log parser
Write blocker
A write blocker is an essential tool in digital forensics that allows read-only access to a storage device, preventing any data from being written to it. This is crucial for preserving the integrity of the original evidence during the forensic imaging process. A hashing utility is used to create a digital fingerprint of the data to verify its integrity before and after imaging, but it does not prevent alterations. A log parser is used to analyze log files, not to acquire a disk image. A chain-of-custody form is a procedural document used to track the handling of evidence but is not a technical tool that prevents data modification.
