Certified in Risk and Information Systems Control (CRISC) — Question 771

Which of the following will be MOST effective in uniquely identifying the originator of electronic transactions?

Answer options

• A. Edit checks
• B. Encryption
• C. Multifactor authentication
• D. Digital signature

Correct answer: D
