Why do we need to set-up firewall
Firewall is a package of programs which protect your private network from viruses and other malicious programs.

By blocking software applications from external sources, firewall provides ultimate protection to our computer from different kinds of cyber attacks.
In this article we will discuss about how firewall becomes successful at blocking such programs:
- Why do we need a firewall?

Why do we need a firewall?
When we surf the Internet, we expose ourselves to a range of cyber attacks like identity theft and loss of financial information. Online connection between a computer and external software applications can leave a computer system vulnerable to several malicious attacks, the purpose of which is to cause serious damage to your PC and also to your identity and financial status. Therefore, whether you are running a home or an office network, it is important to install a firewall program so that it can block software applications from unknown sources.
How does the system work?
The firewall setup takes its place between the server and other computers in the network for protecting the information. It keeps an eye on the data that streams from and to your computer so that any potential risks can be identified. Before you install it on your computer, a criteria is configured according to which it blocks software applications from unknown sources. If any traffic does not meet this criterion, the firewall blocks it from accessing your computer.
Advantages of installing firewall
It allows the users to configure it as per their requirements and preferences. For example, if you enter your credit card details on a site, the firewall will alert you if the site does not have a strong encryption technology support. You can also choose to disable ActiveX and JAVA which are known to be loopholes through which most of the virus threats are made while surfing over the Internet. If these are disabled, you will significantly reduce your exposure to cyber attacks.
What are the risk factors?
If you are using a dial up connection, then you are at lower risk as compared to cable or DSL connections. However, the risks are still there. Hackers are always on the lookout for open machines and whenever they notice such a computer system, they attack it for any possible information. In broadband connections, the machines have open access points and therefore, they are more vulnerable to be attacked by hackers. The program vigilantly watches the traffic funneling through it and provides you a longer living computer machine and also protection from hackers.
