Burning Bridges
is Bad, But
Firewalls are
Good

When you signed up for that ultra-fast DSL or Cable
connection there was probably one very important piece
of information that your ISP failed to mention. By
accessing the Internet via a high-speed connection, you
have tremendously increased your chances of being
victimized by a computer hacker.
Dial-up may not have seemed like it could have held any
advantages, but it actually did have one upside. It is
much less prone to hacking. Every time you dialed-in
your computer was assigned a new IP address. That
unique IP address made you a moving target that was
more difficult for hackers to hit.

With a high-speed connection you are assigned a static
IP address (it never changes). So, your computer went
from being a moving target to staying still with a bulls-
eye pasted on the side. That, coupled with the fact that
with a high-speed connection your computer is always
online, are ideal conditions for a potential hacker attack.
That seemingly beneficial always-on connection gives
hackers a 24/7 open invitation to try and hack your
system. Once inside they can access personal or
financial details, compromise your computer's operating
system, or unleash a virus, worm, or spyware.

Which Firewall is Right For You?
Now that you know how vital a firewall is to the protection of your PC
you have to decide which firewall is right for you. Software or hardware.
A software firewall is designed to monitor your computers activity at all
times. Think of it as a bodyguard who won't let anyone into your
computer if he doesn't like the look of them. With a software firewall
you may to have to assist in protecting your system. The firewall might
alert you to certain activity and ask you if you want to grant or deny
permission. It's just like the bodyguard that was mentioned before. He
needs the okay before telling someone to scram. After you give either
the thumbs up or the thumbs down the firewall will take the appropriate
action and remember your reply so that you won't be asked in the
future.
If you feel comfortable installing and configuring hardware, then you
might want to consider a hardware firewall in the form of a Cable/DSL
router. The hardware firewall handles everything on its own without any
input from you and you also won't have to read any reports or make any
decisions. The firewall handles everything on its own. Installation,
however, can be tricky, so this option is definitely more suited to the
advanced computer user.

My Firewall is Installed. Now I'm Safe, Right?
With your new firewall in place you are probably thinking that
your computer is impenetrable, right? Well, maybe not. As
important to the security of your system as a firewall is, some
do have their limits. Most software firewalls won't scan your
system for viruses that can harm your computer and there
aren't any hardware firewalls on the market that offer virus
protection. That means that you are still vulnerable to attack.
The best line of defense against viruses that can harm your
system is anti-virus protection. You can either buy a separate
anti-virus program or shop around for a software firewall with
anti-virus protection built-in. You may never be able to make
your computer 100% hacker-proof, but the installation of a
firewall coupled with anti-virus protection will greatly reduce
your chances of becoming a hacker's next victim.
