Just about everyone who uses a computer is aware of how important a desktop firewall can be for keeping a system protected. But most people don’t really understand what can happen if they decide not to use this type of safety mechanism. As a result, many computer systems are attacked by malicious software and often crash. This is also the number one reason that identity theft is constantly increasing.

Any incoming or outgoing data transmissions that are suspicious or unauthorized will be blocked by desktop firewall software. Computer operating systems have many points of access, called ports.Think of these ports as working much like the harbor ports around the world. The only difference is that software ports are designed to handle the transmission of data.

On average, an operating system includes as many as 70,000 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. Programs like instant messengers, email clients, software that offers automatic updating, remote service software, and even PC games all use these ports for communication with the outside world. They are also used to connect various computers, in small and large networks.

Unfortunately all of this information exchange through your computer’s ports also makes if easily susceptible to outside attack, this makes firewall software vital to the safety of your computer. 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. While the many different types of malicious software have unique actions the all wreak havoc on 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. Once your personal information has been collected or entered, it is then sent back to the creators of the software, who then use it for the purpose of stealing your identity. Having a desktop firewall installed on your computer can prevent these programs from entering your system by overseeing the traffic on your ports, and blocking those ports that are the ones most often abused.

Firewalls allow you to specify which inbound programs will be allowed entry, and which are not. The same applies for outbound connections. 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.

Some people who have no spyware protection can lose huge amounts of valuable data due to these malicious types of software. This is the reason why it’s vital to make sure to back up all your most important information, such as data of a financial nature and tax records, at least once a month.It is recommended that businesses back up their data on a daily basis, or at least once a week, depending on the type of data that is in question. That way, in case there is a problem, you will be able to restore all your information easily.

The only way to be certain you are protected from malicious software and other computer software parasites is to install a desktop firewall. Malicious software exists to assist in the destruction of computer operating systems and the crime of identity theft. A firewall software is still only as effective as it’s user allows it to be because many programs need the user to confirm certain activities. Always use the internet carefully, with intelligence, and avoid unsolicited e-mails.
