A security technician is decommissioning magnetic hard disk drives (HDDs) containing sensitive financial files. Arrange the following steps in the correct chronological sequence for executing a compliant hardware sanitization and disposition lifecycle.
- 1Log the drive serial numbers and document the initial chain-of-custody form.
- 2Expose the magnetic drives to a degaussing wand or high-power electromagnetic field.
- 3Pass the sanitized drive chassis through an industrial mechanical shredder.
- 4Receive and archive a signed Certificate of Destruction for legal auditing.
Answer
The correct chronological sequence begins with documenting chain of custody, followed by magnetic degaussing, physical shredding, and finally archiving the Certificate of Destruction.
The hardware disposition lifecycle follows a strict sequence: first, inventory logging establishes chain of custody; second, media sanitization (degaussing) renders the magnetic data unreadable; third, physical destruction (shredding) prevents hardware recovery; and fourth, administrative auditing secures a Certificate of Destruction.
