Write Blocker Definition: A write blocker enables read-only forensic access to storage, preventing evidence modification to preserve integrity and chain of custody for court.
A write blocker is a forensic tool that permits read-only access to a storage device while preventing any modification of its contents, preserving the integrity of digital evidence. Hardware write blockers are physical devices inserted between the suspect drive and the analysis workstation, while software write blockers enforce read-only access at the operating system level. Their use is essential to maintaining chain of custody and ensuring evidence is admissible in court.
