Why You Need A Computer Firewall
July 29, 2008
ven the rise in numbers of computer hackers, scammers and viruses around the Internet, you should install a firewall. It is a firewall is responsible for defending your computer from any malicious data that may enter it. A dangerous attack could wipe out your data or steal personal information if you don’t have one.
Determine the type of firewall required by your computer as there are a wide variety available. A computer that came installed with the Microsoft Windows XP or Windows Vista operating system is likely to have a firewall already set up and ready to use. It is no good if it is turned off or not working properly. Your own software needs to be purchased if you do not have one of these later operating systems. Even if you own Windows XP, you should consider a separate firewall program as this version of windows XP version hasn’t had great reviews when it comes to firewall protection.
There are many popular products available for trial download such as PCTools Security Suite, AVG Free and of course McAfee and you can either visit a store that sells computer software or download a firewall product through the Internet. Prices vary depending on sophistication of the software, but there are also plenty of low cost versions available, it is best to stick with more reliable companies. You need to take a few things into consideration prior to installing your firewall. The program must not stop you using the functions that you need, especially if you need to have file and printer sharing on your home network. The settings can be configured during installation or later by using the documentation provided.
Access to certain parts of the Internet is limited by a firewall. If you use a local area network or a router this may happen, so you should be aware how you connect. Secured networks in particular are difficult to access when you have installed a firewall in place. Installing a firewall to a pc linked to a company network may require a specific settings configuration to allow you to connect to them and this can be provided by a company’s IT department.
Installing a computer firewall is not as hard as you think. All the documentation you need is bundled with your software package and there is usually a 24/7 support desk to assist you. To have a stand alone firewall is far better than having a internet intruder steal your valuable information or install some malicious file without your knowledge to track your every move while online.
