NetWare Link State Protocol (NLSP) A protocol that gathers routing information based on the link-state routing method. Its precursor is the Routing Information Protocol (RIP). NLSP is a more efficient routing protocol than RIP.
NetWare Loadable Module (NLM) A component used to provide a NetWare server with additional services and functionality. Unneeded services can be unloaded, thereby conserving memory.
network A group of devices connected by some means for the purpose of sharing information or resources.
network access control (NAC) The set of standards defined by the network for clients attempting to access it. Usually, NAC requires that clients be virus free and adhere to specified policies before allowing them on the network.
Network Address Translation (NAT) See IP proxy.
network attached storage Storage, such as hard drives, attached to a network for the purpose of storing data for clients on the network. Network attached storage is commonly used for backing up data.
network-based IPS (N-IPS) An intrusion prevention system that is network based. To prevent the intrusion, it must first detect it (thus making it a superset of IDS), and then act accordingly.
Network Basic Input Output System (NetBIOS) The native protocol of Windows PCs. It provides a 15-character naming convention for resources on the network. NetBIOS is a broadcast-oriented network protocol in that all traffic is available to all devices in a LAN. The protocol can be transported over NetBIOS Extended User Interface (NetBEUI), TCP/IP, or Internetwork Packet Exchange/Sequenced Packet Exchange (IPX/SPX).
Network Control Protocol (NCP) The protocol Point-to-Point Protocol (PPP) employs for encapsulating network traffic.
Network File System (NFS) A protocol that enables users to access files on remote computers as if the files were local.
network interface card (NIC) A physical device that connects computers and other network equipment to the transmission medium.
Network Interface layer The lowest level of the TCP/IP suite; it is responsible for placing and removing packets on the physical network.
Network layer The third layer of the OSI model, it is responsible for logical addressing and translating logical names into physical addresses. This layer also controls the routing of data from source to destination as well as the building and dismantling of packets. See also Open Systems Interconnection (OSI) model.
Network Operations Center (NOC) A single, centralized area for network monitoring and administrative control of systems.
network operating system (NOS) The software enabling networking; NOS can be on a LAN or WAN.
network sniffer A device that has access to the signaling on the network cable.
network-based IDS (N-IDS) An approach to an intrusion detection system (IDS), it attaches the system to a point in the network where it can monitor and report on all network traffic.
network-based IPS (N-IPS ) See host-based IPS (H-IPS).
New Technology LAN Manager (NTLM) The protocol that Microsoft Windows-based operating systems use for authentication with remote access protocols.
NFS See Network File System (NFS).
NIC See network interface card (NIC).
nonessential service A service that isn’t necessary to keep the server operating at the expected level in its expected role.
Noninterference model A model intended to ensure that higher-level security functions don’t interfere with lower-level functions.
nonrepudiation Verifying (by whatever means) that data was seen by an intended party. It makes sure they received the data and can’t repudiate (dispute) that it arrived.
notification The act of being alerted to an event.
notification policies A set of rules about what triggers notification.
Novell Distributed Print Services (NDPS) A Novell-designed printing system that uses NetWare Directory Services (NDS), known as eDirectory in NetWare
