CISSP study material · question 163 of 500

A field team drills a hole through each retired drive and records the media as destroyed. Why does NIST SP 800-88 reject this?

  1. Drilling is acceptable only for media categorised at moderate impact or above.
  2. Drilling is a purge technique and the record should say purged instead.
  3. Drilling damages only part of the media, and a laboratory may still recover what survives.
  4. Drilling counts as destruction only if the hole passes through the controller board.

Answer: C. Drilling damages only part of the media, and a laboratory may still recover what survives.

Techniques such as bending, cutting, drilling or shooting may only partly damage the media, leaving portions accessible to state-of-the-art laboratory recovery, so they do not achieve destruction.
