CompTIA CySA+ (CS0-003) — Question 475

An organization was compromised, and the usernames and passwords of all employees were leaked online. Which of the following best describes the remediation that could reduce the impact of this situation?

Answer options

• A. Multifactor authentication
• B. Password changes
• C. System hardening
• D. Password encryption

Correct answer: B

Explanation

The correct answer is B, as changing passwords immediately helps to prevent unauthorized access with the leaked credentials. While multifactor authentication (A) enhances security, it does not address the immediate risk posed by the exposed passwords. System hardening (C) and password encryption (D) are important security practices but do not directly mitigate the impact of leaked passwords in the short term.
