Authentication, Authorization, and Accounting (AAA) provides a uniform
framework for configuring these three security functions to implement network
security management.
AAA usually uses a client/server model, where the client runs on the network
access server (NAS) and the server maintains user information centrally. In an AAA
network, a NAS is a server for users but a client for the AAA servers, as shown in
Figure 227.
