Password Protection and Authentication

What is a password?

• A public combination of characters used to gain access to a system or account.

• A physical key used to unlock a door.

• A type of food.

• A secret combination of characters used to gain access to a system or account.

Define authentication.

• Authentication is the process of encrypting data

• Authentication is the process of verifying the identity of a user or system.

• Authentication is the process of securing a network

• Authentication is the process of authorizing access to a system

What is a passphrase?

• A passphrase is a type of dance move

• A passphrase is a type of tropical fruit

• A passphrase is a sequence of words or other text used to control access to a computer system, program, or data.

• A passphrase is a type of currency used in ancient civilizations

Explain the concept of two-factor authentication.

• Two-factor authentication involves using the same password twice for verification

• Two-factor authentication is a process that only requires one form of identification

• Two-factor authentication is a security measure that is not commonly used

• Two-factor authentication is a security process that requires two different forms of identification to verify a user's identity.

What is a biometric authentication method?

• A biometric authentication method is a security process that uses a password to verify an individual's identity.

• A biometric authentication method is a security process that uses unique biological characteristics to verify an individual's identity.

• A biometric authentication method is a security process that uses facial recognition to verify an individual's identity.

• A biometric authentication method is a security process that relies on physical keys for identity verification.

Define password hashing.

• Password hashing is the process of converting a password into a fixed-length string of characters using a random algorithm.

• Password hashing is the process of converting a password into a variable-length string of characters using a mathematical algorithm.

• Password hashing is the process of converting a password into a fixed-length string of characters using a mathematical algorithm.

• Password hashing is the process of converting a password into a fixed-length string of characters using a graphical algorithm.

What is a brute force attack?

• A brute force attack is a term for solving complex mathematical equations

• A brute force attack is a type of dance move

• A brute force attack is a method used to bake cookies

• A brute force attack is a trial-and-error method used to obtain information such as a user password or personal identification number (PIN). It involves systematically checking all possible keys or passwords until the correct one is found.

Explain the concept of salting passwords.

• Salting passwords involves adding a random string of characters to a password before hashing it.

• Salting passwords is the same as hashing passwords

• Salting passwords means storing passwords in plain text

• Salting passwords involves encrypting the password with a public key

What is a CAPTCHA?

• A CAPTCHA is a type of video game

• A CAPTCHA is a type of social media platform

• A CAPTCHA is a type of computer virus

• A CAPTCHA is a challenge-response test used to determine whether the user is human or not.

Define social engineering in the context of password protection.

• Using biometric authentication to access passwords

• Encrypting passwords with a secure algorithm

• Requiring users to change passwords every 6 months

• Manipulation of individuals to divulge confidential information through psychological tactics.
