Finch, a security professional, was instructed to strengthen the security at the entrance. At the doorway, he implemented a security mechanism that allows employees to register their retina scan and a unique six- digit code, using which they can enter the office at any time. Which of the following combinations of authentication mechanisms is implemented in the above scenario?
Correct Answer: A
The combination of authentication mechanisms that is implemented in the above scenario is biometric and password authentication. Biometric authentication is a type of authentication that uses an inherent factor, such as a retina scan, to verify the identity of the user. Password authentication is a type of authentication that uses a knowledge factor, such as a six-digit code, to verify the identity of the user. By combining biometric and password authentication, Finch has implemented a two-factor authentication (2FA) system that requires the user to provide two different types of authentication factors to gain access to the office. 2FA is a more secure way of authentication than using a single factor, as it reduces the risk of unauthorized access due to stolen or compromised credentials.Biometric and password authentication is a common 2FA method that is used in many applications, such as banking, e-commerce, or health care123.References: * Network Defense Essentials Courseware, EC-Council, 2020, pp. 3-28 to 3-29 * What is Biometric Authentication?, Norton, July 29, 2020 * What is Two-Factor Authentication (2FA)?, Authy, 2020
