Firewall and its importance for PC security
Have you ever had a lock on your front door? How about a peep hole or a security camera? Living in the 21st century, it would be absurd if you have no way of keeping the ‘bad guys’ out of your house. Likewise, you wouldn’t barricade your house to the point that your friends and family couldn’t come in. Therefore, it shouldn’t be any different when it comes to your computer or your PC. That is the function of a firewall – to keep the wrong people out and allow the right people to go in.
The advantages of using a firewall
- Firewall filters the right kind of files. You would be mindful of malware, spyware, viruses and Trojans. These malicious files can destroy your PC if you even let one of these in. You can easily contract malware if you go to pornography sites in which malicious files and scripts are heavily laden.
- You will also need to update your malware regularly. Anything that man can conceive, man can break it apart. Therefore it is necessary that you learn how to get the latest software details. Do not for a second believe that old firewalls can protect you.
Problem with firewall
However, as good as firewalls are, there are also certain drawbacks. High speed broad band Internet connections might be affected by the firewall as well. Because the firewall scans all data, it will definitely slow down your Internet speed, especially when you are surfing or downloading files and torrents.
At the end of the day, you need to weigh the pros and cons of using a firewall. Of course, it is more important to have one on at all times because you will never know when there are malicious spywares lurking around the corner. The Internet is a very dangerous place if you are not careful.
