3DES
Triple Data Encryption Standard—a FIPS-approved NIST standard for data encryption
using 192-bits (168-bit encryption, 24 parity bits) for protecting sensitive (unclassified)
U.S. government (and related) data. NIST amended and re-approved 3DES for FIPS in
May, 2004.
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 Technologies products, a user-defined, 16-digit hexadecimal value that pro-
vides network authentication for all devices authorized to communicate over a Fortress-
secured network. Network authentication is one of the components of Multi-factor
Authentication™.
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 Technologies products, a password that guards against unauthorized modifi-
cations 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.”
