CISSP study material · question 161 of 500

A disposal record classifies degaussing as a destroy technique because the drive is unusable afterwards. How does NIST SP 800-88 Rev. 2 classify degaussing?

  1. As a physical purge technique, not an approved destroy technique.
  2. As outside the standard, since it is a vendor-specific process.
  3. As a clear technique, since it is applied through the drive's own interface.
  4. As a destroy technique, but only for tape media.

Answer: A. As a physical purge technique, not an approved destroy technique.

SP 800-88 Rev. 2 lists degaussing among physical purge techniques and states that at the time of writing it is not considered an approved destroy technique.
