What an amazing world we live in! Almost anything you can imagine
can be researched, compared, admired, studied, and in many cases,
bought, with the click of a mouse. The Internet has changed our
lives, putting a world of opportunity before us. Unfortunately, it
has also put a world of opportunity into the hands of those whose
motives are less than honorable. A firewall, a piece of software or
hardware that erects a barrier between your computer and those who
might like to invade it, is one solution.
If you’ve been using the Internet for any length of time,
you’ve probably received some unsavory and unsolicited
e-mail. If you run a business, you may be worried about the
security of your data and your customers’ privacy. At home,
you want to protect your personal information from identity thieves
and other shady characters. Firewalls For
Dummies¯® will give you the lowdown on
firewalls, then guide you through choosing, installing, and
configuring one for your personal or bus iness network.
Firewalls For Dummies¯® helps you
understand what firewalls are, how they operate on different types
of networks, what they can and can’t do, and how to pick a
good one (it’s easier than identifying that perfect melon in
the supermarket.) You’ll find out about
* Developing security policies
* Establishing rules for simple protocols
* Detecting and responding to system intrusions
* Setting up firewalls for SOHO or personal use
* Creating demilitarized zones
* Using Windows or Linux as a firewall
* Configuring Zone Alarm, Black ICE, and Norton personal
firewalls
* Installing and using ISA server and Fire Wall-1
With the handy tips and hints this book provides, you’ll
find that firewalls are nothing to fear – that is,
unless you’re a cyber-crook! You’ll soon be able to
keep your data safer, protect your family’s privacy, and
probably sleep better, too.
