What is a Firewall?
A system designed to prevent unauthorized
access to or from a
private network.
Firewalls can be implemented in both hardware and software, or a combination of
both. Firewalls are frequently used to prevent unauthorized
Internet users from
accessing private networks connected to the Internet, especially
intranets.
All messages entering or leaving the intranet pass through the firewall, which
examines each message and blocks those that do not meet the specified
security criteria.
| There are several types of
firewall techniques:

How do I get Firewall Protection?
HARDWARE: If you have a cable modem or a DSL Router (not modem) you
basically have a firewall. The built in mechanism that scrambles the IP address
in these devices accomplishes the same thing as a stand alone firewall device.
SOFTWARE: There are also software
firewall programs that can protect you, however the configuration of these
programs can be a little tricky. You may want to get professional assistance (of
course we can help you) before trying to do this yourself. If anything software
firewall programs protect you too well. Right out of the box the default
settings are too high. If the software vendors would lower these settings a
notch, customers would not get so frustrated when it attempts to block programs
and utilities that they want to use.

Can I have too much firewall
protection?
YES. This is a very common mistake made by
internet users. They will have 2 or more firewalls turned on
at the same time.
The problem is that it will start blocking
everything making it very frustrating to search the
internet. |
For example, Windows has a built in
firewall, your Internet security software such as Nortons, AVG, McAfee
etc has a firewall and your router
by its true nature also has a firewall. You need only ONE of these not
all 3. Pick one stick with it and your internet experience will be much
faster.
