  2. Times Past • In the past, the only people that needed firewalls were: • Banks • Businesses • Government Facilities • Now, you need firewalls like you need anti-virus protection. http://www.aarp.org/learntech/computers/howto/a2003-06-20-firewalls.html

  3. What is a firewall? • A firewall is a security measure that protects a computer or a computer network from unauthorized access. • Hackers seek out all sorts of personal information including information from everyday home computer users. http://www.aarp.org/learntech/computers/howto/a2003-06-20-firewalls.html

  4. Firewalls Prevent… • A firewall can be software, hardware, or a combination of both. A good firewall will prevent hackers from accessing a computer. It will also keep information from being sent out from your computer without your knowledge. It will keep personal information safe. http://www.aarp.org/learntech/computers/howto/a2003-06-20-firewalls.html

  5. Firewalls Prevent… • Firewalls don't prevent virus attacks but in some circumstances they can stop viruses from sending information from an infected computer. http://www.aarp.org/learntech/computers/howto/a2003-06-20-firewalls.html

  6. How Firewalls Work • The easiest way to get a firewall for your computer is to use a software program that you install just like any other program. Most software firewalls prevent unauthorized information from going out of your computer as well as from going out. You will, however, have to check before you obtain the firewall software to make sure that it is this type of two-directional firewall. http://www.aarp.org/learntech/computers/howto/a2003-06-20-firewalls.html

  7. How Firewalls Work • Some firewalls only alert you when some unauthorized person is trying to enter your computer to access information. These one-directional firewalls do not check for unauthorized information that may be leaving your computer. http://www.aarp.org/learntech/computers/howto/a2003-06-20-firewalls.html
