GLOSSARY
A
AAA
Authentication, authorization, and accounting (AAA) is a term for a framework for intelligently
controlling access to computer resources, enforcing policies, auditing usage, and providing the
information necessary to bill for services. These combined processes are considered important for
effective network management and security. A system in IP-based networking to control what computer
resources users have access to and to keep track of the activity of users over a network.
AAA client IP
address
An IP address of the AAA client, used to configure the AAA client in Access Control Server (ACS) to
interact with the network device. To represent multiple network devices, specify multiple IP addresses.
Separate each IP address by pressing Enter.
AAA server
A server program that handles user requests for access to computer resources and, for an enterprise,
provides authentication, authorization, and accounting (AAA) services. The AAA server typically
interacts with network access and gateway servers and with databases and directories containing user
information. The current standard by which devices or applications communicate with an AAA server
is the Remote Authentication Dial-In User Service (RADIUS).

system entities that are permitted to access the resource.
Access Control
System (ACS)
A AAA server that performs authentication, authorization, and accounting to manage devices in a
network.
Access Control
Service
A security service that provides protection of system resources against unauthorized access. The two
basic mechanisms for implementing this service are ACLs and tickets.
AP
access point. The Hub of a wireless network. Wireless clients connect to the access point, and traffic
between two clients must travel through the access point.
access policies
The policies that limit access to the ACS web interface by IP address, TCP port range, and secure socket
layer (SSL).
AR
access registrar . A RADIUS-compliant, access policy server designed to support the delivery of dial,
ISDN, and new services including DSL, cable with telco-return, wireless and Voice over IP
ADR
