Glossary
A
ACL:
Access Control List. Used within network security systems to allow selective use of services. An
Access Control List is used to control access to, and denial of, services. It lists the services available
with a corresponding list of the hosts permitted to use the service.
Active Directory:
A Microsoft directory service for use in Windows environments. Administrators
use Active Directory to assign enterprise wide policies, deploy programs to many computers, and
apply critical updates to an entire organization. Active Directory functions much like an online
phone book, storing information about resources on the network while providing a means of
centrally organizing, managing, and controlling access to these resources.
AES (Advanced Encryption Standard):
A block cipher adopted as an encryption standard by the
U.S. government.
Aggregation:
The act of collecting something together. In Network Storage Aggregation, you can
put together pieces of networked storage into one, logical storage unit.
B
Bonjour:
Apple’s version of the Zeroconf. Used to automatically configure devices and discover
services on an IP network, Bonjour is the most widely used implementation of Zeroconf. On the Mac,
Bonjour lets Safari Web browser users find the Zeroconf-enabled Web servers in the network. Web
servers are widely used not just for HTML pages, but function as control panels for a variety of
network devices such as routers and Webcams. There is also a Bonjour plug-in for Internet Explorer
which is used to discover Bonjour-enabled network printers and devices. (It was originally named
Rendezvous.)
C
CIFS:
Common Internet Filesystem. A protocol that evolved out of SMB (Server Message Block). CIFS
is an application-level network protocol mainly used to share files, printers, serial ports, and
miscellaneous communications between nodes on a network. It also provides an authenticated Inter-
process communication mechanism. It is mainly used by Microsoft Windows-equipped computers.
Coldplug:
Often taken to mean the opposite of hotplugging. In other words, the inability of a
computer system to add or remove hardware without powering the system down.
D
DAS:
Direct Attached Storage. Also referred as Server Attached Storage and Captive Storage. The
storage device (such as disk drive or RAID array) is directly attached to a computer. The computer
uses various adapters and standardized protocols, such as SCSI and Fibre Channel, to access the
storage device.
DFS:
Distributed Filesystem. This system, developed by Microsoft, lets you build a hierarchical view
of multiple file servers and shares on the network.
