Home Networking Services Firewalls


What is a Firewall?

A firewall is a set of related programs, located at a network gateway server, that protects the resources of a private network from users from other networks. (The term also implies the security policy that is used with the programs.) An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling what outside resources its own users have access to.

Why do I need a Firewall?

As more and more business need to share information with clients, business partners and remote workers the Internet presents itself as an ideal tool. The internet is boosting the efficiency of businesses, improving communications and providing an almost never ending source of data, so it is no surprise that more and more businesses are investing in broadband internet connections allowing always-on access.

Unfortunately these benefits are not without risk. The problems come when the realization that your companies connection is not only allowing access to the Internet 24 hours a day, but also anyone on the Internet has access to you! Your network is now part of the Internet and there are people who can roam around your files and records via the same tool that has enabled your business to grow.

It has be reported repeatedly in the press of high profile corporations falling victim to hackers, some of which just want to deface the corporate website with ‘cyber graffiti’, and there are other more damaging hackers that wish to damage or even steal the privileged information that you store on your computers.

Without the standard protection offered by security devices like a firewall then these unscrupulous individuals could cause you not only inconvenience when they crash your systems but thousands if not tens of thousands in lost data, files, clients and time.
