Firewall Protection

 

Now-a-days safety and security does not just solely mean the guarding of one’s residence by the installation of alarm safety systems and security cameras. The same safety and security precautions are now required for computer users who browse the Internet and share data and other pertinent information. Usually, this protection can be employed by using a Firewall.
​
A computer without Firewall Protection is like a house without a gate. Hackers can easily invade the computer for there is no protection. There are different kinds of Firewalls both in software and the hardware. Users need to be aware of these things in order to protect their computer.

What is a Firewall?

 

In computer language a Firewall is software or hardware-based network security system that controls the incoming and outgoing network traffic by analyzing the data packets, and determining whether they should be allowed or disallowed. This is based on a set of predetermined rules. A Firewall establishes a barrier between a trusted, secure internal network and another network. Obviously, the Internet is not assumed to be secure and trusted without you taking personal responsibility for your Online Safety.

Why Use a Firewall?
A Firewall is needed because it will serve as the protection for the computer. There are very many variations when it comes to the levels of protection a computer can use. This depends on the needs of the computer. A different protection is needed by a computer which is being connected to the Internet and a computer which is being connected to a network. 

 

Little do people realize that using the Internet is really risky. This may sound like bad news for some, but really, there is need for the use of the Internet to be controlled most of the time. This is where Firewall Protection comes in. If by any chance the user really needs to be connected to the Internet all the time, then this is the time when the Firewalls have to be set. Having Firewall Protection will restrict certain kinds of data that is entering the computer. Individuals do not need to be experts in computer to understand this simple logic.

​
There are actually default Firewalls that are set on every computer. If there is need to change the setting of the Firewall, it can be done easily. Users are usually informed whenever they make changes on what is happening so it will not be that difficult to understand.

Firewalls work in two known ways. The first one is that it has the ability to monitor the data entering the system or the computer. The Firewall can therefore decide whether a particular data can be trusted and allowed or not. This is known as the Packet Filter. As the name implies, the Firewall will filter the packet of data passing through the computer.
​
The second component on the other hand mostly deals with the setting up of policies that will govern the applications installed on the computer. This is sometimes called the Application Filter. Basically, this will take charge in figuring if a program can be received or not.

Using Firewall Protection will definitely keep a computer protected. But then, it is important to understand that an antivirus system should also be used in order to help the Firewall. The computer user should be responsible enough when sharing files. There are tons of Firewalls in the market so be sure to get the one appropriate for your needs. However, it is very rare to find one that is for free. There are free trial offers by most Firewall Developers to those who want to try before they buy.
