CISSP study material · question 153 of 500

A department proposes to sanitize printed patient records by running them through a bulk degausser, arguing this parallels how it handles tapes. What is wrong with the proposal?

  1. Degaussing works on paper only above a certain field strength.
  2. Hard copy can only be sanitized by destruction; neither clear nor purge applies to it.
  3. Degaussing is a clear technique, and clear is too weak for medical records.
  4. Hard copy must be purged first and destroyed afterwards.
Show the answer

Answer: B. Hard copy can only be sanitized by destruction; neither clear nor purge applies to it.

SP 800-88 Rev. 2 states that neither the clear nor the purge method is ever appropriate for hard copy; destruction is the only method that applies.
