When you install firewall settings, what it primarily does is check information that comes from the Internet or from other networks and it either rejects or blocks information if it is irrelevant or which can create problems to the system. When the information passes through this barrier, it means that the data is not harmful in any manner and the computer lets the information to pass to your computer where you access the information.
A firewall essentially protects the computers from unwanted virus which gain access to the computer through networks or the Internet. A firewall also stops your computer from sending dangerous and malicious software to other computers. Thus firewall can be defined in simple terms as a barrier or a protection measure installed in the computer to block unwanted information which can hamper the computer systems while we work on these systems. All the windows XP versions have firewall software like the original windows XP, Windows XP service Pack 2 and windows XP Service pack 3.
The firewall can be installed by yourself if you are competent in using computers. On the other hand, if you are not sure how to install it then you can easily get help from professionals.

Working of firewall management
The firewall setting usually follows two systems of working
€ One is the default- deny policy
€ Another is the default - allow policy
In case of a default - deny policy, the firewall systems list the allowed network services that are allowed to be accessed by the computer and the rest of the data are denied access.
In case of a default - allow policy, the system lists the networks which are not allowed access and the rest are allowed to be accessed.
The default - allow policy is much more popular due to easy accessibility whereas the default deny policy is a bit more rigid pattern of working which might not be well suited for our modern times of working though technically it is a better model than the default allow fire wall settings.
