AAA Overview
AAA enables the security appliance to determine who the user is (authentication), what the user can do
(authorization), and what the user did (accounting).
AAA provides an extra level of protection and control for user access than using access lists alone. For
example, you can create an access list 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 might not always know IP addresses
of these users, you can enable AAA to allow only authenticated and/or authorized users to make it
through the security appliance. (The Telnet server enforces authentication, too; the security appliance
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.
