There are many different software, firewalls out there, for use, and for download. Zonealarm, Sygate, and the avast firewall, to name a few. Firewalls help to secure your computers files and data, not only from outside intruders, but just as important, helps to protect you from programs running on your system from sending out data to other sources. In fact, it can be argued, firewalls are more
. important to restraint the programs and software on your own computer, then protecting you from the odd port scanner out there in cyberspace. You see, the programs on your computer are the ones that can access your important information the easiest, then send out that information to whatever sources it chooses. The hackers and scanners are on the outside, trying to look and get in. Firewalls can stop any program you select from accessing the Internet.
