Microsoft Internet Security and
Acceleration Server 2000
The service that allows IPX name resolution on Firewall client
The process by which a server behind ISA can publish to the
World Wide Web (WWW) without compromising security. See also
hosting and publishing.
SecureNAT is an extension of the Windows 2000 NAT driver.
ISA Server's secure network address translation (NAT) feature
provides a degree of address transparency for networked clients.
NAT substitutes a global IP address, valid on the Internet, for an
internal IP address. ISA Server enhances the underlying NAT
functionality in Windows 2000, by enabling access control for
FTP, Windows NetMeeting for H.323, and T-120 protocols. It also
enables rerouting HTTP requests, which can then frequently be
satisfied by a local cache. This enhancement greatly improves HTTP
performance and lowers bandwidth requirements.
Sockets Layer (SSL)
A protocol that supplies secure data communication through data
encryption and decryption. SSL enables communications privacy over
A transport-level protocol developed for use in Novell NetWare
networks. SPX is used in place of TCP to verify packet delivery,
ensure proper sequencing of packet data, and provide connected
service between devices on a network. See also Internetwork
Packet Exchange (IPX).
Software that makes up the smallest unit of console extension.
One snap-in represents one unit of management behavior (for
example, the Windows 2000 event log viewer is a functional
unit of management and thus a good candidate to become a snap-in).
Technically, snap-ins are OLE InProc servers.
A logical communications channel used by TCP/IP applications.
Sockets are data structures created by using a combination of
device IP addresses and reserved TCP/UDP port numbers to indicate
connection and delivery service information. See also Windows
A protocol for traversing firewalls in a secure and controlled
manner, made available to the public by the Internet Engineering
Task Force (IETF).
A snap-in that provides functionality even if loaded alone in a
console that has no other snap-ins.
Filters that allow packets from other administrator-selected
services from the Internet. A static filter is created during
configuration of ISA by using the user interface. If IP packet
filtering is enabled, the static filter is always on.
A method provided on a WINS server to assign a static
(unchanging) IP address to a client.
A database query and programming language widely used for
accessing data in, querying, updating, and managing relational
database systems. See also SQL
A TCP/IP configuration parameter that extracts network and host
configuration from an IP address. This 32-bit value enables the
recipient of IP packets to distinguish the network ID portion
(domain name) of the IP address from the host ID (host name).
access-control list (SACL)
A list that controls the generation of audit messages for
attempts to access a securable object. The ability to get or set an
object's SACL is controlled by a privilege typically held only by
A Windows 2000 Server network server application that
remotely manages the computers on a network. SMS detects computers
on the network, inventories software and hardware configurations,
and installs client applications from a central location.
