Certified in Risk and Information Systems Control (CRISC) — Question 254

Which of the following helps ensure compliance with a non-repudiation policy requirement for electronic transactions?

Answer options

• A. Digital signatures
• B. Digital certificates
• C. One-time passwords
• D. Encrypted passwords

Correct answer: A

Explanation

Digital signatures provide a way to confirm the authenticity and integrity of a message, ensuring that the sender cannot deny having sent it, thus fulfilling non-repudiation requirements. Digital certificates, one-time passwords, and encrypted passwords serve different purposes in security and do not specifically guarantee that a party cannot deny their involvement in a transaction.
