What Do You Know About Biometrics And Password Security?

1. Authenticating a user by the normal actions that the user performs is called behavioral biometrics.

True

False

Behavioral biometrics refers to the process of authenticating a user based on their unique behavioral patterns and actions, such as typing rhythm, mouse movements, or voice patterns. This method is considered more secure than traditional authentication methods like passwords or fingerprints, as it is difficult for an imposter to mimic someone else's behavioral characteristics accurately. Therefore, the given statement that authenticating a user by the normal actions they perform is called behavioral biometrics is true.

2. A secret combination of letters, numbers, and/or characters that only the user should know is called a ________

A secret combination of letters, numbers, and/or characters that only the user should know is called a password. A password is used as a security measure to protect sensitive information or gain access to a particular system, account, or device. It acts as a barrier to unauthorized access and ensures that only authorized users can gain entry.

3. A password attack that creates encrypted versions of common dictionary words and compares them against those in a stolen password file is called a hybrid attack.

True

False

The given statement is false. A password attack that creates encrypted versions of common dictionary words and compares them against those in a stolen password file is actually called a dictionary attack, not a hybrid attack. A hybrid attack is a combination of different attack techniques, such as a dictionary attack and a brute force attack, to increase the chances of successfully cracking a password.

4. A hardened operating system that can keep attackers from accessing and controlling critical parts of a computer system.

Hardened OS

Standard OS

Trusted OS

Secure OS

A trusted operating system refers to a secure and reliable operating system that has implemented various security measures to protect critical parts of a computer system from unauthorized access and control by attackers. It incorporates features such as access controls, encryption, and secure boot mechanisms to ensure the integrity and confidentiality of the system. This type of OS is designed to withstand attacks and maintain the trustworthiness of the system, making it a suitable choice for environments that require a high level of security.

5. A brute force attack is an encryption attack in which every possible combination of letters, numbers, and characters is used to create encrypted passwords that are matched with those in a stolen password file.

True

False

A brute force attack is not an encryption attack where every possible combination of letters, numbers, and characters is used to create encrypted passwords. Rather, it is a method of trying every possible combination of passwords until the correct one is found.
