What is a Firewall?
I am going to go over the bare basics of firewalls, and if you need more than that there are TONS of firewall information sites out there! I know when I started to learn about firewalls years ago it was overwhelming at times! A firewall's job is basically the same thing as a physical firewall! It keeps destructive sources AWAY from your property! If you have been using the Internet for any length of time, and especially if you use one at work you may have heard the term FIREWALL before! You might have heard some coworkers mention they can't go to a certain site, because it won't let it pass the firewall! The above picture may be a corporate setup, or a home network. You have the Internet with all its dangers, and the firewall basically helps to filter OUT some of the items you DON'T want near your company or home computer! If firewall sees harm it won't allow you to view the material. Firewalls aren't perfect, and they can stop you from seeing or using perfectly...
