The Cisco Secure ACS Paradigm
Cisco Secure ACS provides authentication, authorization, and accounting
(AAA—pronounced “triple A”) services to network devices that function as AAA
clients, such as a network access server, PIX Firewall, or router. The AAA client

functionality and uses one of the AAA protocols supported by Cisco Secure ACS.
