Azure Active Directory user authentication exemplifies which security principle?

1. Integrity

2. Availability

3. Confidentiality

4. Authentication

The correct answer is: Integrity

The principle demonstrated by Azure Active Directory user authentication is primarily related to the concept of authentication itself. In the context of security principles, authentication involves verifying the identity of a user or system. Azure Active Directory provides mechanisms such as username/password combinations, multi-factor authentication, and various protocols like OAuth and SAML to ensure that the identity of users is confirmed before granting access to resources. While integrity, availability, and confidentiality are critical components of a comprehensive security model, they do not directly capture the essence of the user authentication process. Integrity refers to the accuracy and trustworthiness of information, availability ensures that systems and data are accessible when needed, and confidentiality protects sensitive information from unauthorized access. However, authentication specifically deals with the processes that confirm user identities and establish trust, making this concept the most fitting in the context of Azure Active Directory's authentication mechanisms.
