Certified in Risk and Information Systems Control (CRISC) — Question 133

Which of the following is MOST effective against external threats to an organization's confidential information?

Answer options

• A. Single sign-on
• B. Strong authentication
• C. Data integrity checking
• D. Intrusion detection system

Correct answer: B

Explanation

Strong authentication is crucial as it ensures that only authorized users have access to sensitive information, effectively mitigating the risk of unauthorized access. Single sign-on simplifies user access but doesn't enhance security against external threats. Data integrity checking verifies data accuracy, while an intrusion detection system monitors for threats but does not prevent them.
