MRP
Mesh Radio Port—in Fortress Secure Wireless Bridges, a pair-wise network link formed
between WDS-enabled BSSs configured on the Bridges.
MSI The Microsoft installer system written by Microsoft for Windows platforms.
MSP
The Fortress protocol that provides authentication and encryption at the Media Access
Control (MAC) sublayer, within the Data Link Layer (Layer 2) of the Open System Inter-
connection (OSI) networking model.
Multi-factor Authentication™
In Fortress Technologies products, the combination of network authentication (through
the network Access ID), device authentication (through the Device ID), and user
authentication (through user credentials), that guards the network against unwanted
access.
multiplexing The practice of transmitting multiple signals over a single connection.
NetBIOS
Network Basic Input/Output System—an API that originally provided basic I/O services
for a PC-Network and that has been variously adapted and augmented to support cur-
rent LAN/WLAN technologies.
network authentication
In Fortress Technologies products, the requirement that all devices must authenticate
with the correct
Access ID
in order to connect to the Fortress-secured network; one of
the factors in Fortress’s Multi-factor Authentication™.
network resource
An entity on the network that provides a service or function, such as e-mail or printing,
to devices and users on the network.
NIC
Network Interface Card—computer circuit board that enables a computer to connect to
a network.
NIAP
National Information Assurance Partnership—a collaboration between NIST and the
National Security Agency (NSA), in response to the Computer Security Act of 1987 (PL
100-235), to promote sound security requirements for IT products and systems and
appropriate measures for evaluating them.
NIST
National Institute of Standards and Technology, the U.S. Government agency responsi-
ble for publishing FIPS.
NMP
Non-Mesh Point—in Fortress Secure Wireless Bridges, any node on a Fortress FastPath
Mesh network that is not an MP.

NTLM Windows NT LAN Manager—a user authentication protocol developed by Microsoft®.
operating mode
In Fortress Technologies products, the way in which access controls and cryptographic

PDU
Protocol Data Unit—often synonymous with
packet
, a unit of data and/or control infor-
mation as defined by an OSI layer protocol.
PKI
Public Key Infrastructure (PKI), a system of digital certificates and other registration
authorities that authenticate the validity of each party involved in an Internet transac-
tion; sometimes, trusted hierarchy.
policy
The means by which access to the secure network and its resources are controlled for
users, devices and groups.
PPP
Point-to-Point Protocol—a method for communicating TCP/IP traffic over serial point-to-
point connections.
