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

AAuthorization

BAuditing

CAuthentication

DAccounting

Show Suggested Answer

Suggested Answer: C

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 what resources they access and what changes they make.

Thus, the correct answer is C. Authentication.

I feel confident about that answer too. Authorization comes later.

I remember a practice question that asked about the AAA model, and I think it emphasized that Authentication is the first step in verifying identity. So, I’d go with C) Authentication.

I’m a bit confused between Authentication and Authorization. I know they’re different, but I can’t recall which one is specifically for identity verification.

I feel like we covered this in class, and I think it was about how users prove who they are. So, C) Authentication seems right.
