Class 6.04: Firewall

Another type of software to use in conjunction with antivirus software is Firewall Software. A firewall’s job is similar to a physical firewall that keeps a fire from spreading from one area to the next. A firewall can be used to protect your home network and family from offensive websites and potential hackers.

Firewalls work like a filter between your computer/network and the Internet. You can program what information or data you want to let out and what information or data you want to let in. Everything else is blocked.

Many of the antivirus software packages have firewalls built into them. The Windows OS also has firewall software available. Click on the links below to learn more about the Windows and ZoneAlarm firewall software.
