Glossary
The following terms and definitions are used in this book, and in other
ProCurve Management Software documentation.
802.1X: A port-based authentication protocol that can dynamically
vary encryption keys, and has three components: a supplicant,
an authenticator, and an authentication server.
ACL: Access control list – A list or set of rules that routers (and
other networking endpoints) use to control and regulate
access through the endpoint and subsequently onto the net-
work. In NAC 800, using this option restricts the network
access of non-compliant endpoints by assigning DHCP set-
tings on a quarantined network.
ACPI: Advanced Configuration and Power Interface – A specifica-
tion that establishes standard interfaces.
ACS: Access Control Server – A server that controls access to your
system. A Cisco® access policy control platform.
AD: Active Directory – A directory service included with
Microsoft® Windows Server 2003 that allows administrators
to manage end-user access to the network.
ActiveX: A Microsoft technology that enables interactive Web content.
agent: An information exchange process that works in conjunction
with clients and servers to perform tasks.
agentless credentials: When NAC 800 accesses and tests endpoints, it needs to know
the administrator credentials for that endpoint. If your net-
work uses a Windows domain controller and the connecting
endpoint is a member of a configured domain, NAC 800 uses
the information supplied to access and test the endpoint.
AP: Access Point – The physical point at which an endpoint or
device connects to a network.
