Which component of the AAA service security model provides identity verification?

The AAA service security model consists of three components: Authentication, Authorization, and Accounting.

•Authentication: This is the process of verifying the identity of a user or device. It ensures that only legitimate users can access the network or service.

•Authorization: This determines what an authenticated user is allowed to do or access within the network.

•Auditing/Accounting: This component tracks the actions of the user, including whatresources they access and what changes they make.

Thus, the correct answer is C. Authentication.
