Fabric: The hardware and software that connect a network of storage devices to one another, to servers and eventually to clients.
LUN masking: Using the Logical Unit Number (LUN) of a storage device, or a portion of a storage device, to determine which storage resources a server or host may see.
Port: A physical connection on a storage switch that links that switch to storage devices, servers or other switches. Many SAN security techniques limit which devices a port can connect to or the manner in which it connects to those devices.
Spoofing: Impersonating the identity of an individual (such as a storage administrator) or of a device (such as a storage switch) to gain unauthorized access to a storage resource.
Trusted switch: A switch within a storage network that uses a digital certificate, key or other mechanism to prove its identity.
VSAN: A virtual SAN, which functions like a zone but uses a different layer of the Fibre Channel protocol to enforce which devices in the fabric can speak to other devices.
World Wide Name: A unique numeric identifier for a device on a storage network, such as a disk array or a switch.
Zone: A collection of Fibre Channel device ports that are permitted to communicate with each other via a Fibre Channel fabric.
