The Importance of Firewalls to Network Security
Most networks should have a firewall in place before they are up and running. A firewall is the most common form of network security employed by companies large and small. If you own a personal computer your anti-virus software company may at one time or another have offered you firewall protection.
A firewall on a home network is just as important as one on a corporate network. Why? Most smaller networks have as many security issues that larger corporate networks have. A firewall helps protect a network against potential data loss, corruption and hackers.
What Is A Firewall
A firewall is nothing more than a fancy term used to describe a blockade that prevents outside forces from accessing your network. It is called a firewall because it prevent information or data loss from one place to another. Typically
a firewall is some program or hardware that you have to install in your computer that helps filter information coming from the Web to your computer network. A firewall provides a series of filters that screens information allowing only safe information to pass through to your network.
In a large company, multiple computers are often linked using network cards. Companies usually provide multiple connections to the Internet. In order to protect all of these computers a firewall is necessary so that only certain people can access corporate computers through the Web (those that are authorized to do so). While a firewall is not foolproof it basically does a good job of protecting computers from Internet threats at their connection points.
