To help prevent dictionary login attacks, which policy should Donald enable?

• A. Data protection policy
• B. Lockout
• C. Account recovery
• D. Multi-factor authentication

Answer: (B)

Enabling a lockout policy is an effective measure to help prevent dictionary login attacks. Dictionary attacks involve an attacker systematically entering every word in a predetermined list (dictionary) as potential passwords in an attempt to gain unauthorized access to accounts. By implementing a lockout policy, the system can temporarily disable an account after a specified number of failed login attempts. This makes it significantly more difficult for attackers to succeed in guessing the password, as their attempts will be limited. The threshold for failed attempts can be set to a level that balances usability and security, ensuring that legitimate users are not overly impacted while still providing protection against automated guessing attacks. Other policies like multi-factor authentication add an extra layer of security by requiring more than just a password, which would be beneficial too, but the lockout policy directly addresses the immediate threat of repeated failed login attempts that characterize dictionary attacks. While data protection and account recovery policies are important for overall security, they do not specifically mitigate the risks posed by dictionary attacks as effectively as a lockout policy does.
