Full Description
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 ZoneAlarm, BlackICE, and Norton personal firewalls
Installing and using ISA server and FireWall-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.
