Proxy
Is a
server that sits between a client application, such as a web
browser, and a real server.When a client program makes a request,
the proxy server responds by translating the request and passing it
to the Internet. When a computer on the Internet responds, the proxy
server passes that response back to the client program on the
computer that made the request. The proxy server computer has two
network interfaces: one connected to the LAN and one connected to
the Internet.
The
primary security features of Proxy Server are:
-
It blocks inbound connections.
-
LAN clients can initiate connections to Internet servers, but
Internet clients cannot initiate connections to LAN servers.
-
It can restrict outbound connections.
