A firewall configuration is good also essential to ensure the lock on the door of his works. firewalls are most often available in two forms, or be a piece of hardware that sits between the computer and the Internet or firewall could be a specialized software that is installed on your computer. Both are generally accepted, although this author prefers the flexibility of a hardware firewall. A properly configured firewall can do much to ensure good security, but is not a panacea, there are other measures.

Consider the following scenario:

You have a computer with all software patches and updates and even went to buy a brand new firewall. Have you read the manual of the firewall has been configured by the owner as well. Do you like a couple of weeks of Web surfing happy, I'm downloading mp3 left and right and share images with family by email. Do you have an Internet connection bandwidth to large files are downloaded with ease, even the screen saver interesting news of your father sent you last night was 2 Mb, downloaded in a matter of seconds. Life is beautiful ... until you have installed the screen saver. But strange things happen. The files are missing and others are not open and your friends are sending e-mail saying they continually receive an e-mail with strange things in the subject line - you know not send emails. You think your computer may be infected by a virus! How can this be, since you have installed the latest security patches and have shiny new firewall protects the gateway to the Internet?

If you have antivirus software installed last year and has not been updated, as it only detect viruses that are known at this time. All the latest viruses can not be found. It is therefore important not only to buy antivirus software quality from a reliable supplier, but also to ensure that they maintain. This author prefers to update your antivirus software every day. Most antivirus software has a new car for update "feature that can take the guesswork out of the equation.

Now we have a good antivirus software installed on your computer, we have a three-tier system composed of layered defense by:
