Glossary
802.11 The IEEE standard that specifies technologies for wireless networks.
802.11i
The amendment to the 802.11 standard that describes security for wireless networks,
or
Robust Security Networks .
802.1X
The IEEE standard for port-based network access control, providing authentication and
authorization to devices attached to a given port (or preventing access from that port if
authentication fails).
802.16
The IEEE standard that specifies technologies for fixed broadband wireless MANs that
use a point-to-multipoint architecture, also called WiMAX, WirelessMAN™ or the Air
Interface Standard.
Access ID
In Fortress products, a user-defined, 16-digit hexadecimal value that provides network
authentication for all devices authorized to communicate over a Fortress-secured net-
work. Network authentication is one of the components of Multi-factor Authentica-
tion™.
access point (AP)
A device that transmits and receives data between a wired LAN and a WLAN, to connect
wireless devices within range to the LAN.
AES
Advanced Encryption Standard—a FIPS-approved NIST standard for 128/192/256-bit
data encryption for protecting sensitive (unclassified) U.S. government (and related)
data; also referred to as the
Rijndael algorithm . NIST FIPS-approved AES in November,
2001.
administrator password
In Fortress products, a password that guards against unauthorized modifications to the
system or its components (compare user password).
APIPA
Automatic Private IP Addressing—a Microsoft feature that allows a DHCP client unable
to acquire an address from a DHCP server to automatically configure itself with an IP
address from a reserved range (169.254.0.1 through 169.254.255.254). The client uses
the self-configured IP address until a DHCP server becomes available.
ARP
Address Resolution Protocol—describes how IP addresses are converted into physical,
DLC addresses (ex., MAC addresses).
AS
Authentication Server—a network device running an authentication service: software
that checks credentials to verify the identity of network users and/or devices in order to
restrict access to the network or to its resources or to track network activity.
Autonomous System—as defined by RFC 1930, a network or connected set of networks,
usually under a single administrative entity, with a single clearly defined routing policy;
“the unit of routing policy in the modern world of exterior routing.”
BPM
In FIPS, bypass mode—state in which cleartext is allowed to pass on an encrypted
interface.
bridge A network device that connects two networks or two segments of the same network.
BSS
Basic Service Set—the primary collection of entities associated in a wireless network, as
defined in the IEEE 802.11 standard.
