Certified Information Systems Auditor (CISA) — Question 58

An organization is planning to re-purpose workstations that were used to handle confidential information. Which of the following would be the IS auditor's BEST recommendation to dispose of this information?

Answer options

• A. Overwrite the disks with random data.
• B. Reformat the disks.
• C. Erase the disks by degaussing.
• D. Delete the disk partitions.

Correct answer: A

Explanation

The best recommendation is to overwrite the disks with random data because it ensures that the original data is irretrievably destroyed. Reformatting the disks and deleting partitions may not effectively remove all traces of the confidential information, while degaussing is not always feasible for all types of disks.
