In AAA, authorization controls what resources and services a user may access after identity is established, so granting access to network assets and limiting which services are available are authorization functions. Accounting tracks and reports user activity, including session details such as connection duration, and it provides usage/reporting data such as user access reports. The remaining statements describe authentication, which verifies identity and can use TACACS+ for validation.
