Some Information on Firewall
Given the rise in numbers of computer hackers, spammers and viruses around the Internet, you should install a firewall. Between your computer and data that is entering it firewall is your first line of defense. It stops your computer being prone to dangerous attacks that can negatively impact upon you.
The type of firewall required for your computer should be ascertained since there is a wide variety available including those from major corporations such as Microsoft. If you already have a computer that came installed with the Microsoft XP or Vista operating system, then chances are that your firewall is already set up and ready to be used.
It is no good if it is turned off or not working properly. Purchase your own software if you do not have one of these newer operating systems. Owners of Microsoft XP may still want to purchase separate firewall software as the XP version doesn’t get great reviews.
The many products available, include Norton, AVG, and McAfee and can be purchased in store or downloaded from the internet. Prices vary depending on sophistication of the software, but there are also plenty of low cost versions available, even from the big name companies.
You need to take a few things into consideration prior to installing your firewall. These programs can block certain functions that you need, so you must configure it to allow those, such as file and printing sharing. Settings can be configured during installation or at a later date using the documentation provided.
Firewalls tend to stop you from going to certain parts of the Internet as well. You should be aware how you connect as this may happen if you use a local area network or a router. Accessing secured networks when you have installed a firewall is difficult. 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.
