Proxy Server A proxy server acts as an intermediary between the PCs on your network
and the Internet.
The main features of a proxy server are:
■ Centralized access to the Internet for all the PCs on your network.
■ Web content filtering
■ Internet access restricted to authorized users.
In most cases, proxy servers also support authentication (also known as
logging) whereby the users must provide a username/password before
connecting to the Internet. This ensures that only authorized personnel
are able to access the Internet.
