Which technique involves the system checking its own password strength by cracking guessable passwords?

• A. Complex password policy
• B. User education
• C. Reactive password checking
• D. Computer-generated passwords

Answer: (C)

The technique that involves the system checking its own password strength by attempting to crack guessable passwords is known as reactive password checking. This method assesses the strength of user-generated passwords by simulating what an attacker might do to guess those passwords. By analyzing the password against common patterns, dictionary attacks, and previously compromised password data, the system can effectively determine if the password meets security standards. If a user’s password is found to be weak or easily guessable, the system can prompt the user to create a stronger password, enhancing overall security.

In contrast, a complex password policy refers to the set of requirements that dictate the characteristics a password must possess, such as length, complexity, and the use of symbols or numbers. While it contributes to stronger password creation, it does not involve actively testing the strength of passwords after they have been set.

User education involves training users on best practices for creating and managing passwords but does not include a system mechanism for checking password strength after creation.

Computer-generated passwords, while generally complex and secure, do not involve the system checking its own passwords; rather, they focus on automatically generating passwords that are usually of high strength and randomness.

Thus, reactive password checking uniquely identifies a system-based approach to assess the strength of passwords already
