Final answer:
Write-blocking technology is not solely software or firmware based; it can also be implemented as physical devices for enhanced security in maintaining the integrity of digital evidence.
Step-by-step explanation:
The assertion that write-blocking technology is only software or firmware based is false. Write-blocking technology can be implemented in both hardware and software/firmware forms. The primary function of write-blocking is to prevent any alterations to the storage device being worked on, which is critical in digital forensics to maintain the integrity of the evidence.
Hardware-based write-blockers are physical devices that sit between a computer and a storage device, such as a hard drive or a USB flash drive, ensuring no new data is written to the storage device. Meanwhile, software-based or firmware-based write-blockers are programmatic methods that achieve the same goal but can be more vulnerable to tampering or bypassing compared to their hardware counterparts.
