D. None

Answer 1

OPtion C is answer. An SMS-based password authentication protocol addresses the aspect of confidentiality in information security.

Step-by-step explanation:

The additional layer of security provided by an SMS-based password authentication protocol addresses the aspect of confidentiality in information security. Confidentiality refers to the protection of sensitive information from unauthorized access. By adding an SMS-based password authentication protocol in addition to the username/password combination requirement, the organization ensures that only authorized users can gain access to the system, thereby maintaining the confidentiality of the information.

When an organization implements an SMS-based password authentication protocol as an additional layer to the username/password combination, this addresses the aspect of Confidentiality in information security. This approach is part of a multi-factor authentication process that makes it harder for unauthorized users to access sensitive data because they would need not only the user's password but also access to their phone to receive the SMS code. It ensures that information is accessible only to those who should have access to it.
