Certified Information Systems Auditor (CISA) — Question 336

Which of the following is a method to prevent disclosure of classified documents printed on a shared printer?

Answer options

• A. Producing a header page with classification level for printed documents
• B. Encrypting the data stream between the user's computer and the printer
• C. Using passwords to allow authorized users to send documents to the printer
• D. Requiring a key code to be entered on the printer to produce hard copy

Correct answer: D

Explanation

The correct answer, D, is effective because it ensures that only individuals who know the key code can access the printed documents, thus preventing unauthorized viewing. While A, B, and C provide some level of security, they do not fully restrict access to the physical output of the printer, which is critical for protecting classified information.
