AAA Overview
AAA provides an extra level of protection and control for user access than using ACLs alone. For
example, you can create an ACL allowing all outside users to access Telnet on a server on the DMZ
network. If you want only some users to access the server, and you do not know their IP addresses, you
can enable AAA to allow only authenticated and/or authorized users to make it through the FWSM. (The
Telnet server has its own authentication; the FWSM prevents unauthorized users from attempting to
access the server.)
You can use authentication alone or with authorization and accounting. Authorization always requires a
user to be authenticated first. You can use accounting alone, or with authentication and authorization.
This section includes the following topics:
AAA Performance, page 12-2
About Authentication, page 12-2
