EAP-FAST (EAP-Flexible Authentication via Secure Tunneling) - A publicly accessible IEEE
802.1X EAP type developed by Cisco Systems and supported by the BSC. EAP-FAST uses
symmetric key algorithms to achieve a tunneled authentication process.
Encryption - Scrambling data so that only the authorized recipient can read it. Usually a
key is needed to decrypt the data.
ESSID (Extended Service Set Identifier) - A type of unique identifier applied to both the AP
and the wireless PC Card that is attached to each packet. This allows the AP to recognize
each wireless client and its traffic.
H
H.323 - A protocol standard for multimedia communications. H.323 was designed to
support VoIP and other real-time transfer of audio and video data over packet networks.
The standard involves several protocols each handling specific details of Internet
telephony.
HTTPS (HyperText Transmission Protocol, Secure) - A variant of HTTP used for handling
secure transactions. HTTPS is a unique protocol that is simply SSL underneath HTTP. You
need to use "https://" for HTTP URLs that use SSL, whereas you use "http://" for HTTP
URLs without SSL. The default "https" port number is 443, as assigned by the Internet
Assigned Numbers Authority.
I
IEEE (Institute of Electrical and Electronics Engineers) - An organization involved in setting
computing and communications standards.
IDS (Intrusion Detection System) - The Bluesocket BSC provides an administrator-
configurable Intrusion Detection System (IDS) to defend itself and the network it is
protecting from intruders, worms, and other targeted attacks.
IPSec (IP Secure) - A protocol that provides security for transmission of sensitive
information over unprotected networks such as the Internet. IPsec acts at the network
layer, protecting and authenticating IP packets between participating peer devices.
K
Kerberos - An authentication system enabling protected communication over an open
network using a unique key called a ticket.
L
L2TP (Layer 2 Tunneling Protocol) - An IETF standard protocol for creating Virtual Private
Networks. L2TP is an open standard with mutli-vendor interoperability and acceptance.
You can configure the Bluesocket BSC to support L2TP over IPSec such that IPSec secures
the traffic and L2TP provides both a tunnel and authentication between the wireless client
and the BSC.
LDAP (Lightweight Directory Access Protocol) - LDAP defines a relatively simple protocol
for updating and searching directories running over TCP/IP. An LDAP directory entry is a
collection of attributes with a name, called a distinguished name (DN). The DN refers to
the entry unambiguously. Each of the entry's attributes has a type and one or more
values.
M
MAC (Media Access Control) address - A hard-wired address applied at the factory. It
uniquely identifies network hardware, such as a wireless PC Card, on a LAN or WAN.
