Network Security

Two important elements of a network security strategy are the use of proxy servers and firewall systems.

A firewall system acts as a protective layer to network access by controlling the traffic that passes between the interfaces on a system. Proxy servers allow you to centralize access to the Internet and therefore provide a way to control and monitor network access.

In this tutorial, we will also examine how other security measures such as port blocking, password policies, and encryption fit into network security strategy. We also take a quick look at the purpose and characteristics of extranets and intranets.
