Cisco Secure ACS helps centralize access control and accounting, in addition to router and switch access management. With Cisco Secure ACS, network administrators can quickly administer accounts and globally change levels of service offerings for entire groups of users.
Cisco Secure ACS supports Cisco AAA clients such as the Cisco 2509, 2511, 3620, 3640, AS5200 and AS5300, AS5800, the Cisco PIX Firewall, Cisco Aironet Access Point wireless networking devices, Cisco VPN 3000 Concentrators, and Cisco VPN 5000 Concentrators. It also supports third-party devices that can be configured with the Terminal Access Controller Access Control System (TACACS+) or the Remote Access Dial-In User Service (RADIUS) protocol. Cisco Secure ACS treats all such devices as AAA clients. Cisco Secure ACS uses the TACACS+ and RADIUS protocols to provide AAA services that ensure a secure environment.
