Internet Firewalls - Are These Deterrents As Effective As We
by Stacey Misope

Can you imagine using your furnace without a filter or
expecting one filter to trap all dust and pollutants for the
lifetime of the furnace? That's how some people approach
protecting their computers from viruses and other invaders.
More than likely, you understand the importance of a furnace
filter and how it only functions for a certain amount of
time efficiently before it needs replacement. The same goes
for an Internet firewall. The protectors work best when
frequently upgraded so they can block nasty spam and other
destructive forces. Since those nasty bugs find unique ways
to wiggle throughout your system, you need to use a firewall
in a smart manner.
So, is it pointless to use firewalls in the first place? By
no means should you bypass these security systems. Without
a firewall, metaphorically speaking, you're leaving your
system open to flooding that will push so much debris into
your computer that you're computer will either lock up
entirely or steal every bit of information off your
computer. Fortunately, firewalls can adapt too and improve
to keep up with these mutating infiltrators as long as you
make the effort to continually upgrade your firewall.
The best way to protect your computer from infiltrators is
to build several tough layers between your system and the
invader. A firewall works in several layers arranged like a
maze to throw off invaders and tear them apart. These
layers and tunnels work similar to how a sound wave is
broken apart by loosing momentum and speed. As viruses
change after learning the language of a firewall, the
firewall has to work even harder to keep up with these
changes. That is why upgrades are so essential to your
system's protection.
Anytime you operate a computer that's connected to another
system, you run the risk of encountering an encrypted
message with destructive or invasive goals. Would you run
through a battleground solo without armor? Running through
the Internet the same way without a firewall would be just
like that foolish maneuver. To gain the best protection,
your system needs several layers of protective gear found in
a firewall often called circuit relay, packet filtering and
application gateway. Simply put, whatever want to enter
your system must pass through a firewall and whatever wants
to leave your system must also pass through another
firewall. As long as information or systems operate
separate from your computer, they must pass through a
firewall. A more in depth discussion on firewall operations
is available at www.pc-help.org.
One multi-layered firewall that is found on nearly every
window system is Windows Firewall. This firewall blocks
unsolicited messages, alerts you of intruders and
automatically updates. The top firewalls for home computers
according to PC World Online include:
ZoneAlarm Free, Sygate Personal Firewall, Tiny Personal
Firewall, Norton Internet Security (for Macintosh), Kerio
Personal Firewall, BlackIce PC Protection, McAfee Personal
Firewall Plus, and VisNetic Firewall.
While some firewalls are free, others are shareware or "buy
only". Since deterrents that destroy information, rob our
personal identity and basically intrude and track our
movement without permission are as big of a threat as ever,
always install the latest version of the best firewall for
your hardware and software.
