Using Windows Firewall
Configuring Windows Firewall
If you use the Internet, a firewall is a must-have security tool. It’s not the only tool you need, but it’s an important one. It protects your computer from hackers and worms. Hackers are people that would attempt to access your computer through the Internet without your knowing it. Worms are bad programs, such as viruses, that are usually written to do intentional harm.
Windows 8 comes with its own built-in firewall. If you didn’t know about it before going online, relax. It’s enabled by default. So most likely it’s been protecting you since the very first moment you went online (also your Internet Service Provider protects you from most invasions). In this chapter, you learn how the firewall works and how to configure it for maximum protection.
