CompTIA A+ Core 2 (220-1102) — Question 84

The network was breached over the weekend. System logs indicate that a single user's account was successfully breached after 500 attempts with a dictionary attack. Which of the following would BEST mitigate this threat?

Answer options

• A. Encryption at rest
• B. Account lockout
• C. Automatic screen lock
• D. Antivirus

Correct answer: B

Explanation

The correct answer is B, as implementing an account lockout policy would prevent further attempts to access the account after a certain number of failed logins, thus mitigating the risk of dictionary attacks. The other options, while beneficial for security, do not specifically address the issue of repeated failed login attempts leading to account compromise.
