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)
ISAKMP (internet
security association
and key management
protocol)
ISP (Internet Service
Provider)
A set of standards created to provide data integrity and confidentiality at
the IP layer of the network stack.
A protocol framework which sets the parameters for a VPN connection by
defining the payload format, how the key exchange protocol will be
implemented, and how the security association will be negotiated.
A company that provides individuals and other companies access to the
Internet and other related services such as Web site building and virtual
hosting. An ISP has the equipment and the telecommunication line access
required to have a point-of-presence (POP) on the Internet for the
geographic area served.
kernel Manages all physical resources, including scheduling of processes, virtual
memory, file system management, reading and writing files to disk or
tape, printing, and network communications. The Sidewinder G2 is run in
one of two kernels: the operational kernel or the administrative kernel.
key pair The reference to a private key and a mathematically-related public key.
The private key is safeguarded by the owner, and known only to them.
The public key can be distributed to anyone. This allows one key to be
used for encryption, and the other key to be used for decryption.
key pair generation The process of generating mathematically-related public/private key pairs.
LDAP Lightweight Directory Access Protocol. An internet standard for directory
services that run over TCP/IP.
