Firewalls
Along with anti-virus software, a firewall is another important
part of your computer’s security. A firewall sits between your
computer and the Internet and will attempt to block any
intrusion attempts from computer hackers and other
malicious sources. Think of it as your computer’s bouncer. It
stands at the door to the Internet and stops unwanted
visitors from getting in.
If you are going to use the Internet it is essential that you
install firewall software (along with anti-virus) as part of a
good security and safety routine.
You can buy software firewalls from computer stores, or
download them from the Internet. These will normally
provide the necessary security for home users or small
businesses. If you need a higher level of security you can
also purchase dedicated hardware firewalls which are used
by large companies.
Microsoft® Windows® XP includes a basic software firewall
to secure your computer while on the Internet. This is the
first time that a firewall has been included with a Windows®
operating system for the home.
