host Any computer connected to a network; for example, a workstation, router,
Sidewinder G2, or server.

A simple programming language used to create Web documents. Hypertext
uses special links that you can click to jump from one related topic to another.
An agreed-upon format (protocol) that requests and transfers HTML
documents on the World Wide Web.
An agreed-upon format (protocol) that requests and transfers HTML
documents on the World Wide Web in a secured manner.
A U.S. non-profit organization designated to allocate IP address space, assign
protocol parameters, perform domain name system management, and
maintain root server systems. Other domain registration companies are
available.
The organization that developed the IPSec standard which protects data on
unprotected (or untrusted) networks such as the Internet.
A key management protocol standard which automates the implementations
of other protocols (ISAKMP, Oakley, etc.) used in a VPN connection.
interface A shared boundary through which information can be exchanged. (An
interface may be a shared portion of computer software accessed by two or
more programs, a hardware component linking two devices, or a device or
program allowing a user to communicate and use the computer or program.)
internal DNS Manages DNS information only available to internal machines. The internal
name server cannot receive queries from external hosts since it cannot
communicate directly with the external network. Resolution of external DNS
information both for the Sidewinder G2 itself and to handle internal queries for
external information are handled by the internal name server. Although it is
unable to communicate directly with external hosts, it is able to send queries
and receive the responses via the external DNS.
IP address A 32- bit address that uses standard dotted quad notation assigned to TCP/IP
network devices. An IP address is unique to each machine on the Internet. An
IP address contains a network and host field.
IP Filter Provides the ability to specify rules to allow IP-based traffic to flow through the
Sidewinder G2 at the network layer. For example, traffic may pass through the
Sidewinder G2 without being passed to the application proxies. IP Filter can
be used for tracking TCP session states, and is sometime referred to as
“stateful inspection.”
IPSec (Internet Protocol
Security)
A set of standards created to provide data integrity and confidentiality at the IP
layer of the network stack.
