Which asset disposal technique ensures that data remnants are rendered physically inaccessible and irrevocable, through degaussing, shredding, or incineration?

• A. Sanitization
• B. Destruction
• C. Certification
• D. Wiping

Answer: (B)

When disposing of assets, the goal is to make data completely unrecoverable by removing the data from the physical medium itself. Destruction achieves this by physically damaging or obliterating the storage device so data cannot be retrieved. Degaussing, shredding, and incineration are classic destruction methods: degaussing erases data on magnetic media, shredding physically tears the device into pieces, and incineration fully destroys it. This level of irreversibility goes beyond logical data removal, which either overwrites data or deletes it but can leave traces or allow forensic recovery. Sanitization removes data to repurpose a device; wiping overwrites data but may not guarantee complete irrecoverability on all media; certification is about proving a process was followed, not about disposing of data. Therefore, destruction is the technique that ensures data remnants are physically inaccessible and irrevocable.
