Managed Remote Subnet - A BSC network configuration in which the local wireless
subnet uses a router that does not use NAT and the BSC uses DHCP to assign IP
addresses to wireless clients on the managed side of the network.
Managed Side - The segment of the network containing wireless clients and wireless
access points. The BlueSecure Controller manages use, quality of service, and security on
this side of the network.
Managed Virtual Interface - BSC configuration used for special networking topologies or
applications that cannot communicate directly with the managed physical interface,
managed-side VLAN, or managed remote subnet.
N
NAT (Network Address Translation) - You may use NAT to map all client IP addresses on
the managed side to the IP address of the BSC protected interface.
NIST (National Institute of Standards and Technology) - NIST's Computer Security
Division is charged with improving the security of information systems.
NTLM (NT LanMan) - NTLM (NT LanMan) is an authentication process that’s used by all
members of the Windows NT family of products. You can configure the BSC to support
NTLM and Transparent NTLM user authentication.
O
OFDM (Orthogonal Frequency Division Multiplexing) - A modulation technique for
transmitting large amounts of digital data over radio waves. 802.11a uses OFDM, as
will 802.11g.
P
Pass-through VLAN - Pass-through VLANs on the BSC receive 802.1q-tagged packets
from one physical interface (typically the managed side) and forward them with the same
tag to the outgoing physical interface (protected side).
PEAP (Protected Extensible Authentication Protocol) - Authentication protocol developed
by Cisco, Microsoft and RSA Security, Inc. PEAP uses a certificate approach to
authentication where a user's identity is verified by a digital certificate.
Preamble - A preliminary signal transmitted over a WLAN to control signal detection and
clock synchronization.
PPTP (Point-to-Point Tunneling Protocol) - A tunneling protocol for connecting Windows NT
clients and servers over Remote Access Services (RAS). PPTP can be used to create a
Virtual Private Network between computers running NT. It is an extension of PPP
sponsored by Microsoft.
Protected side - Internet or enterprise network. The BlueSecure Controller protects this
segment of the network from unauthorized use or access.
Pubcookie authentication - Pubcookie is an open-source package for intra-institutional
single-sign-on end-user web authentication.
Q
QoS - The performance properties of a network service, possibly including throughput,
transit delay, priority. 802.11 and Bluetooth-based networks allow packets or streams to
include QoS requirements.
