In this computer age where everyone is connected online, we enjoy the benefits of online banking, online purchases and many other ways that the computer makes our lives easier. However, by using this convenience, we frequently share personal information online. With the problem of identity theft occurring daily, it is very important for computer users to have firewall software installed on their personal and business computers. Frequently, antivirus software includes firewalls, but sometimes it doesn’t, so if you currently use an antivirus program to help protect your computer from viruses, it is a good idea to verify whether it also contains a firewall program.
The firewalls blocks all of the incoming and outgoing data that is not normal or authorized. If you have this type of program installed on your computer, you will see pop-up messages asking for authorization before certain things are downloaded. This is your software working to protect you from the many viruses, spyware, malicious software or malware, and identity theft programs that are out there trying to trip you up. Your computer has a number of software ports that allow information in and out. In fact, the typical operating system has over seventy thousand ports that handle data transmission. Email, computer games, instant messengers, automatic updates, computer networking, and remote software services are examples of applications that all use ports for communication.
In addition to the regular viruses and malware software that are designed to wreak havoc on your computer, spyware and ransomware are designed specifically to aid in identity theft. These programs can monitor everything that is typed into the machine, and can even lock the machine and demand credit card information before granting access. The information gathered in this way is most often used for identity theft. Some of these parasitic programs will also infiltrate the computer and corrupt data files, forcing you to reformat the computer. This can result in a loss of highly critical data if you are unprepared for these types of occurrences. Backing up data on an external hard drive is a very helpful way to save crucial items even if you have a firewall program.
As you can imagine, it would be impossible to physically check up on each of the ports through which damaging programs try to enter your computer. That is why a firewall is an important part of your overall computer package. Knowing that your firewall software is protecting the many ports in your computer will allow you to move forward without fear. Keeping this software up to date is also important to maintaining your computer’s security. You can rest assured that your computer is protected and that your data is safe.
