Glossary
private key The private key is used to decrypt messages that were encrypted with the
corresponding public key. A private key can also be used to digitally sign
messages. The recipient can use the corresponding public key to verify the
authenticity of the message.
protocol A set of rules by which one entity communicates with another, especially over
a network. This is important when defining rules by which clients and servers
talk to each other over a network. Important protocols become published,
standardized, and widespread.
proxy A software agent that acts on behalf of a user requesting a network
connection through the Sidewinder G2. Proxies accept a connection from a
user, make a decision as to whether or not the user or client IP address is
permitted to use the proxy, optionally does additional authentication, and then
completes a connection on behalf of the user to a remote destination.
proxy server A server that acts on behalf of another server, and may perform tasks such as
caching, access control, or provide a route to a destination server.
Administrators may choose to configure proxy servers as transparent,
meaning the end user is unaware of the proxy server’s presence, or nontransparent,
meaning the end user must authenticate to, or interact with, the
server.
public key A public key is used to encrypt messages that only the holder of the
corresponding private key can decrypt. Public keys can also be used to verify
the authenticity of digitally-signed documents.
public key cryptography A class of cryptographic methods that employ a pair of keys for encrypting and
decrypting messages. A message encrypted with the public key can only be
decrypted with the corresponding private key. Within a public key
cryptography system, the public key may be made public without
compromising the encrypted data. Public key cryptography enables
encryption and digital signatures, and simplifies cryptographic key distribution
through the use of a public key infrastructure.
Quick Start Wizard A Windows-based program that allows you to initially configuration your
Sidewinder G2 or G2 Enterprise Manager.
RADIUS Remote Authentication Dial-In User Service. An authentication protocol
developed by Livingston Enterprises Inc. Recognized by the Internet
Engineering Task Force (IETF) as a dial-in security solution on the
Internet.(RFC 2138).
RAID (redundant array of
individual disks)
678
Stores information on multiple hard disks to provide redundancy. Using RAID
can improve performance and fault-tolerance.
redirected proxy A Sidewinder G2 proxy option that reroutes a connection to a specific host
system, hiding the actual destination address or port from the system
requesting the connection.
