Most people who use computers have been told they should use firewall software to keep their computers safe. But most people don’t really understand what can happen if they decide not to use this type of safety mechanism. This is the reason why there are so many people experiencing their software being attacked, and suffering through computer crashes. The lack of proper firewall protection is also the leading reason for the rise in identity theft.

Desktop firewall software works by screening all of the data that goes in and out of your computer, blocking those that are determined abnormal or unauthorized.  Every computer contains a number of ports, which are the access points of the operating system. Think of these ports as working much like the harbor ports around the world. But with computer ports, it’s data that’s transmitted back and forth.

The average computer operating system may support seventy thousand or more software ports. The reason to have so many of them is due to the fact that people use a great number of programs on a daily basis. Ports are used to communicate through the Internet via instant messengers, email, automatic updating programs, remote services, and even computer games. Ports are also integral to all sizes of computer networks.

The problem is that ports are especially vulnerable and open to unwelcome attacks; therefore, to ensure your PC is protected as fully as possible, you must install a desktop firewall. Millions of computer users have been victimized by a plague of software with malicious intent called by many names: virus, spyware, malware, adware, and the most recent addition, ransomware. Each of these has a different function, but when you get down to it, they are designed to destroy your computer. Spyware and ransomware together are in their own way responsible for rise in identity theft.

While spyware captures your computer activities ransomware debilitates a computer and requests your credit card numbers before it will allow you to use the internet. As soon as your personal financial information is collected by the ransomware, the perpetrators will use it to steal your identity. If you have a desktop firewall, the traffic on your computer ports will be carefully monitored and parasites like these can be blocked from the ports that are used most often.

Through firewall software you can designate which inbound connections you will allow and which ones you want to block. Outgoing data can be screened in the same way. There are occasions when spyware might get into a computer but due to restrictions placed on internet access it cannot return data to it’s creator. Aside from trying to steal your identity, these programs can corrupt your operating system files, making it so that you are forced to reformat your computer’s hard drive.

This can cause you to lose all your important data, and for people who do not have something to block this type of entry, the results can be catastrophic. It is essential that sensitive data like financial records or tax documents are copied or backed up monthly at the very least. Depending on the types of data a business needs to preserve, daily and weekly data backups of certain kinds of information are recommended. So if something unforeseen happens, your data can be easily restored.

Installing a desktop firewall on your computer can protect you against computer viruses and other types of computer parasites. Malicious software exists to assist in the destruction of computer operating systems and the crime of identity theft. A firewall is only as smart as the computer’s user, as many of them require the user to confirm certain events before proceeding. Be conscientious, and surf the web safely and smartly, and avoid questionable emails.
