Which of the following is NOT a category of media sanitization?

Media sanitization refers to the process of protecting sensitive data by removing or destroying it from storage media. The recognized categories of media sanitization include clearing, purging, and destroying.

Clearing involves using logical techniques to overwrite data so that it is no longer easily recoverable. Purging goes further by using more advanced methods that prevent data recovery, including physical destruction of the media itself. Destroying typically implies a complete and irreversible process that renders the data unrecoverable.

Transferring, on the other hand, does not fit into the categories of media sanitization. It refers to moving data from one location to another rather than eliminating or protecting it from unauthorized access. Therefore, the notion of transferring does not align with the intent or purpose of media sanitization processes, which aim to ensure data is adequately removed or destroyed to prevent potential recovery.
