Does Your Computer Need a Firewall?

Does Your Computer Need a Firewall?

Just the other day numbers were released on the number of electronic devices that single homes now average. That number? A few years ago it was 3. Today? 25.

It’s no surprise then that nearly every home in America now has a personal computer or more, and it’s likely that each one of these computers is hooked up to the Internet. The Internet has brought its bundle of improvement and innovation in communication and more in the 21st century now, but it has also given rise to a whole new breed of criminals and miscreants who love to prey on the uninformed or the unsuspecting in order to make a profit or just to have what they think is a little bit of fun.

This is why it is vital that you protect your computer and your information from being accessed by these people, who are becoming ever more innovative when it to comes to achieving their hacking goals. A key instrument in the fight for your computer’s security is a firewall.

What is a firewall?

A firewall is a piece of software or hardware that functions in a networked environment to prevent communication between areas with different degrees of trust. The term comes from the same word as that applied to a construction that is used in construction to keep a fire from spreading if one should start.

The most common type of firewall is the personal firewall, and this type in fact has come with most Windows software from the XP version and after.  The last and current generations of Microsoft Firewalls take the security of the personal and business computer one step further, by offering advanced protection against the phone home capabilities of both viruses and software. These firewalls will allow you to detect any activity that goes out form your computer, so that you know who is receiving information about what you are doing and your transactions online.

The fact is, every personal computer needs a firewall, just as any business system does. But you probably do not have to worry about going out and buying one on its own. Your operating system likely has included one for you.

Rather your job will be to find out how to set your operating parameters, and tell your firewall what to allow and what to block on your computer. It is especially important that you seek help when attempting the manipulation of your firewalls functions whenever possible, as mishandling will render your firewall useless.

If you run into trouble, you can count on your tech from DiverseNet to guide you through the process. Do not adjust the levels until instructed to by your tech on what to do.
