Certified Information Systems Auditor (CISA) — Question 827

Which of the following is the BEST method to prevent wire transfer fraud by bank employees?

Answer options

• A. Two-factor authentication control
• B. System-enforced dual control
• C. Independent reconciliation
• D. Re-keying of wire dollar amounts

Correct answer: B

Explanation

The best option is System-enforced dual control, as it requires two individuals to authorize a transaction, making it more difficult for any single employee to commit fraud. Two-factor authentication is useful but does not prevent collusion among employees. Independent reconciliation is important but does not stop the initial fraudulent transaction, while re-keying wire amounts does not address the underlying issue of authorization.
