Which AAA Component Determines What Resources You Can Access?
Which component of the AAA framework determines what resources an authenticated user can access?
Quick Answer
The answer is authorization. In the AAA framework, authorization is the component that determines what resources an authenticated user can access, operating after authentication has verified the user’s identity. It enforces policies—such as those defined in a local database or via protocols like RADIUS or TACACS+—to permit or deny access to specific network services, commands, or resources. On the ISC2 Certified in Cybersecurity CC exam, this concept tests your understanding of the logical sequence of AAA, and a common trap is confusing authorization with authentication, which only verifies who you are. Remember that authentication asks “Who are you?” while authorization asks “What are you allowed to do?” A simple memory tip is to think of the “A” in authorization as standing for “access rights,” helping you recall that it controls permissions after identity is confirmed.
⚠ Common exam trap
ISC2 often tests the distinction between authentication and authorization by presenting a scenario where a user is successfully logged in but cannot access a resource, and candidates mistakenly blame authentication instead of recognizing that authorization is the missing step.

Correct answer & explanation
✓
Authorization
Authorization is the component of the AAA (Authentication, Authorization, Accounting) framework that determines what resources an authenticated user can access. After authentication verifies the user's identity, authorization enforces policies—such as those defined in a local database or via RADIUS/TACACS+—to permit or deny access to specific network services, commands, or resources.

- ✗
Auditing
Why it's wrong here
Auditing is not a component of AAA; it is related but separate.
- ✗
Accounting
Why it's wrong here
Accounting logs activities.
- ✓
Authorization
Why this is correct
Authorization determines access rights.
- ✗
Authentication
Why it's wrong here
Authentication verifies identity.

AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which THREE components are part of the AAA framework?
hard- ✓ A.Authentication
- B.Accountability
- C.Auditing
- ✓ D.Accounting
- ✓ E.Authorization
Why A: Authentication is correct because the AAA framework (Authentication, Authorization, and Accounting) uses authentication to verify the identity of a user or device before granting access. This is typically done via credentials such as username/password, digital certificates, or tokens, and is the first step in the AAA process.
