Cisco Access Control Security: AAA Administration Services

Chapter 4. Enterprise Authentication Servers

In this chapter, you learn the following topics:

• Cisco Secure Access Control Server software and versions

• The Cisco Secure Solution Engine

Numerous enterprise level authentication servers are on the market today. Popular among these are Funk's Steel-Belted RADIUS server, Livingston Enterprises' RADIUS Authentication Billing Manager, and Merit Networks' RADIUS servers. While these are reputable companies with popular products, they lack the ability to combine both the TACACS+ and RADIUS protocols into a single box solution. Fortunately, the Cisco Secure ACS for Windows Server (ACS) is a one-stop solution for authentication, authorization, and accounting (AAA) via both TACACS+ and RADIUS. This product is the focus of this chapter.
