Having an internet connection using cable modem or DSL, the use of firewall software is your only assurance to protect your computer, your home network and your job from possible hacking to your records you stored in your personal computer. Without these, there are many offensive websites that will send you many unsolicited advertisement or spam messages you found in your e-mail address. It became a nuisance on your part spending efforts to erase the useless information. Every morning when you open your e-mail address, a spam mails is the center of your attention and became the front page of your vision. This was the work of the scam artist or other person whose intention is to let you aware of there presence. What you did was delete all those mails to clean your computer with garbage.

With the use of firewall, you feel relax and more assured as your computer become virtually invisible to anyone who has a bad intention to penetrate to your internet connection and harvest your own personal or bank information for their great advantage. They will not rest until they get what they want and they are expert to this line of dirty work by fooling internet users. Having a firewall software is essential for the protection of your computer.

Always on guard in sending any messages or notes to anyone you knew or other person you want to communicate whether it is your friend or not. There is always possibility that this information will be circulated to other person by your own friends and send them to their own friends also. Such an act will make your e-mail address vulnerable for breach of security when it was found by scam artist giving him the opportunity in using your information to his own personal agenda at your disadvantage and risk.

Don't let other people use your computer unsupervised unless you are willing to give them access to your computer. Using a strong password is a good security measure that no one can open your computer without your knowledge. There are even a kind of computer with a built-in lock before you can start-up.

Never write any password anywhere easy for others to have an unauthorized access to your computer. A spammer can flood your mailbox useless spam mails or sell information to other people without your knowledge and permission. If not in use, turn off your java script or HTML mail readers, outlook and outlook express where this spam mails harassed your system unmolested.

A firewall is used as a barrier to keep out destructive forces away from your system. It is a program or a hardware whose role is to filter all incoming information through internet connection to your private network. Any undesirable information is being flagged by the filter giving no chances to pass through.

Firewall controls the degree of the traffic flowing in and out of the work by packet filtering. Any small data were being analyzed against a set of filters. Packets that make it to pass through into the filter are send to the requesting system and discarded or removed. Any information from the net was retrieved by the firewall then send it to the requesting system. Firewall compare certain key parts of the packets to a database of trusted information. It is then being monitored for specific characterization and compare it. If it match then allows it to pass through. If it will not match, it will be remove immediately.

Another good security measures is installing a spy software. Without it, you can be identified easily by hackers what you are doing in your computer and what websites you had been visiting. This program cannot identify you to get your privacy information easily. Hacker can gather your sensitive information, password and your e-mail address. They can capture your key strokes. Whatever you type is stored in a secret buffer of the machine. They even take your picture and your surfing activities.
