Your Firewall is Important

You can easily download a free software firewall like ZoneAlarm which works pretty well. However, to get even better protection it’s best to use a hardware based firewall appliance also – especially for your corporate network.

Kim Komando writes Firewalls hide your computer or network from Internet threats and can be either hardware or software.
Hackers use programs that roam the Internet and search for open computers. They do this by sending information to IP addresses. If the IP address is unprotected, a message is sent back to the hacker. The hacker then knows your computer can be infiltrated.
Hardware and software firewalls prevent this from happening by only accepting requested information. For example, every time you type in a Web address or access the Internet, you are requesting information. If you type in my home page (, a request is sent to my Web site’s server.
