Cisco Secure ACS centralizes 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. Although the external user database shown in
Figure 1-1 is optional, support for many popular user repository implementations
enables companies to put to use the working knowledge gained from and the
investment already made in building their corporate user repositories.
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. For more information about support for
TACACS+ and RADIUS in Cisco Secure ACS, see
