Security+ Knowledge-Based Authentication

Knowledge-Based Authentication (KBA) is a security measure that:

• requires users to enter a one-time password generated by a mobile app.
• requires users to enter a unique password and username combination.
• involves the use of hardware tokens or smart cards for authentication.
• asks users to answer personal questions about themselves.
• uses biometric factors like fingerprints or facial recognition to verify a user's identity.

Which of the following is a disadvantage of Knowledge-Based Authentication (KBA)?

• It requires additional hardware or software installation on the user's device.
• Knowledge-based questions may have publicly available answers.
• It does not require users to remember any personal information.
• It allows for easy password recovery in case of a forgotten password.
• It provides a high level of security and is difficult to bypass.

In the context of Knowledge-Based Authentication (KBA), what is the term used to describe the process of selecting and verifying user-specific questions?

• Biometric verification
• Question generation
• Authentication
• Password encryption
• Authorization

In Knowledge-Based Authentication (KBA), what is a common method for selecting personal questions?

• Randomly assigning questions to users
• Using pre-determined sets of questions
• None of the above
• Analyzing user behavior to predict question preferences
• Allowing users to choose their own questions

Which of the following is a security vulnerability associated with Knowledge-Based Authentication (KBA)?

• Phishing attacks
• All of the above
• Smart card cloning
• Social engineering attacks
• Brute force password cracking

In Knowledge-Based Authentication (KBA), what is the purpose of asking challenge questions?

• To verify the user's identity by asking questions only they would know the answer to
• To discourage users from using weak passwords
• To confuse hackers who are attempting to gain unauthorized access
• To collect additional personal information for marketing purposes
• To provide users with fun and engaging interaction during the authentication process

Which of the following best describes the concept of challenge questions in Knowledge-Based Authentication (KBA)?

• Questions that ask for personal identification documents
• Questions that only the user would know the answer to
• Questions related to the user's preferences or hobbies
• Questions that require a user to solve a complex mathematical problem
• Questions designed to test the user's general knowledge

Which of the following is true regarding the security of Knowledge-Based Authentication (KBA)?

• It is immune to social engineering attacks.
• It can only be used for online authentication, not for physical access.
• It is not commonly used by organizations due to its high implementation costs.
• It is vulnerable to attacks if personal information is compromised.
• It is the most secure authentication method currently available.

How can organizations enhance the security of Knowledge-Based Authentication (KBA)?

• By allowing users to provide their own questions and answers
• By using highly advanced machine learning algorithms to generate personalized questions
• By requiring users to answer the questions in a specific time limit
• By implementing multi-factor authentication alongside KBA
• By increasing the number of questions asked during the authentication process

Which of the following is a potential drawback of using Knowledge-Based Authentication (KBA)?

• KBA can only be used for authentication on a single device.
• Asking personal questions may violate privacy regulations.
• KBA increases the risk of malicious software attacks.
• Users may forget the answers to their personal questions.
• KBA is only suitable for low-risk applications.
