Final answer:
Write Blockers are devices that create a complete forensic image and validate it without the need for a PC, ensuring the integrity of digital evidence during the imaging process.
Step-by-step explanation:
Write Blockers are devices used to create a complete forensic image and validate without a PC. These standalone devices are essential tools for digital forensics investigators. When dealing with digital evidence, it is crucial to ensure that the original data is not altered; this is where write blockers come into play. Write blockers allow for the read-only access of a storage device, ensuring that the integrity of the evidence remains intact during the forensic imaging process.
Forensic images are exact bit-by-bit copies of the original storage media and are used for detailed examination without compromising the original evidence. The ability to validate the forensic image is an integral part of the evidence handling process, which confirms that the image is a true and accurate representation of the original data. This is often done using hash values (checksums) to ensure the image has not been tampered with during the acquisition process.
