We’ve all heard it, fight fire with fire, but logically that’s clearly wrong. Yet, that phrase holds water (pun intended) when it comes to the internet. Let me explain.
The web is in every household across the nation, and increasingly the world, making proximity irrelevant when connecting with others. Awesome, but with the good comes the bad. A million doors have opened for humanity, but with the access comes viruses, hackers and other nasty internet junk.
That’s why we have firewalls. No person in their right mind would leave their doors open living in the world’s largest city for criminals to waltz in and take their hard-earned 52-inch flat screen. So why leave your computer or network vulnerable to viruses and fishing expeditions?
So, What Is a Firewall?
A firewall is exactly that: a wall! It lies between your home or business network and the internet. However, like fire, the wall is possible to pass through if you have the proper equipment. That is, when you click on a link or type in a website, you’re giving it clearance to pass through the firewall and appear on your screen. I know, it sounds very cloak and daggerish, but you don’t have to be a technical genius to have such protections in place. In fact, you probably already have one or two walls in place.
The Tale of Two Walls
Two types of firewalls exist, and just like the two types of prime computer real-estate, they come as both hardware and software. Wi-Fi requires the use of a router, which in and of itself is an extra piece of equipment between you and your internet experience, thus serving as a passive firewall. But don’t be mistaken, routers alone will not protect your home or office computers, because they’re so basic to bypass by tech nuts and web wizzes. That’s why software firewalls are so important. Software firewalls provide that extra layer of protection. Microsoft automatically provides a standard firewall with versions of Windows XP and newer. Still, these are the same within each operating system, and internet intruders are expecting to encounter these layers.
Yes, onions are the only things that have layers — so does a good internet security system. Think of fire and how easy it is to pass your hand through the tip of a flame, but we would not go raking our hands across the hot coals at its base. The thicker the firewall, the better. This is especially important in business, as multiple computers leave more room for vulnerabilities. You need something a hacker or virus cannot anticipate.
Think about it! It only takes one weak link, or in this case, computer, for an entire system to be infiltrated. Then POOF! There go your trade secrets or confidential information. So, what is not usually anticipated? A good IT team: It’s not just another brick in the wall. Don’t be the weakest link. Work with CMIT Solutions of Centreville today.
