Authentication Quiz for learning

What is the primary purpose of authentication in cybersecurity?

• To protect sensitive data

• To verify the identity of users or systems

• To increase internet speed

• To block spam emails

Which of the following is an example of something you are in authentication?

• A password

• • A fingerprint

• A PIN

• A security question

What is a common method of two-factor authentication?

• Using a username and a password

• Using a fingerprint and a PIN

• Using a password and a one-time code sent to your phone

• Using a password and a security question

Which of the following best describes multi-factor authentication?

• Using multiple passwords

• Only requiring a password for access

• Combining two or more different authentication methods

• Using a single method for all users

Which of the following is NOT a way to mitigate the risks of weak passwords?

• • Use multi-factor authentication (MFA)

• Require users to change passwords frequently

• Use simple passwords for convenience

• Implement a password manager

What does Multi-Factor Authentication (MFA) require?

• A username and password only

• A password and a biometric factor

• Two or more forms of identification to verify identity

• A password and a PIN code

Why should you avoid reusing passwords across multiple accounts?

• It makes it easier to remember passwords

• It increases security in case one account is compromised

• If one account is hacked, all accounts are at risk

• It improves convenience for the user

Biometric authentication (e.g., fingerprint) is foolproof and cannot be hacked.

• YES

• NO

In Unix-based systems, what does the salt value do during password hashing?

• It ensures the password is reversible

• • It prevents multiple users from having the same password hash

• It increases the speed of the hashing process

• It decreases the storage space required for the password hash
