Microsoft Proxy Server v2.0. |
 |
The second part of the documentation goes into Firewall types and
strategies, so if that's the reason you are reading the documentation,
go
straight to that page.
What is Microsoft Proxy Server 2.0?
Microsoft Proxy Server is a "firewall" and cache server. It provides
additional Internet security and can improve network response issues
depending on its configuration. The reason I put the word firewall in
quotes
is because Proxy Server should not be considered as a stand-alone
solution
to a firewall need. When you are done reading this document, you will
have
an advanced understanding of the Proxy Server product and also
understand
firewall techniques and topologies.
Proxy Server can be used as an inexpensive means to connect an entire
business through only one valid IP address. It can also be used to allow
more secure inbound connections to your internal network from the
Internet.
By using Proxy Server, you are able to better secure your network
against
intrusion. It can be configured to allow your entire internal private
network to access resources on the Internet, at the same time blocking
any
inbound access.
Proxy Server can also be used to enhance the performance of your network
by
using advanced caching techniques. The can be configured to save local
copies of requested items from the Internet. The next time that item is
requested, it can be retrieved from the cache without having to connect
to
the original source. This can save an enormous amount of time and
network
bandwidth.
Unlike Proxy Server 1.0, Proxy Server 2.0 includes packet filtering and
many
other features that we will be discussing.
Proxy Server provides it functionality by using three services:
* Web Proxy: The web proxy service supports HTTP, FTP, and Gopher for
TCP/IP
Clients.
* WinSock Proxy: The Winsock proxy supports Windows Sockets client
applications. It provides support for clients running either TCP/IP or
IPX/SPX. This allows for networks that may be running more of a Novell
environment to still take advantage of Proxy Server.
* SOCKS Proxy: The SOCKS Proxy is a cross-platform service that allows
for
secure communication in a client/server capacity. This service supports
SOCKS version 4.3a and allows users access to the Internet by means of
Proxy
Server. SOCKS extends the functionality provided by the WinSock service
to
non-Windows platforms such as Unix or Macintosh.
