But ironically, there are people, who are confused about the fact, that whether firewall is necessary or not. There might be various reasons behind the thought of not having a firewall. People are either unaware about the working of the firewall. They don’t actually understand how it happens and can someone protect their computer. Other fact is that people are so worried or troubled by the internet hacking that they are not ready to trust any external source for protecting their computer, for them, it can be a virus itself.
Nobody is lying, but the perception needs to be changed about the firewalls. Let us first understand what a firewall is and what it does for you. Firewalls are software programs that are specifically designed to safeguard your computer from foreign attacks. They are used to keep the track of the incoming users and the outgoing packets from your computer. You might be amazed how a firewall can understand that this is the same users who have visited or is he a new comer. Does firewall know the name of the person using the computer? But in that case there can be so many persons with a common name. Like, you can many persons with the name Jones connected to your network. If not names, then how?
First, let's look at what a firewall is supposed to do. A firewall is hardware or software that limits access to a computer from an outside source. If your computer will ever be connected to the Internet, a firewall is an essential tool needed to prevent mal ware and hackers from accessing or damaging your computer. It stops harmful access to your computer. It has an algorithm that allows it to bypass those persons which are allowed to enter your area. You can’t imagine the speed of incoming threats. Within seconds your computer can get affected by spywares if you are not safe guarded with a firewall. Thus the answer to your question is yes, all of us need firewalls if we want
to be safe on the internet.
It is recommended to have both a software-based firewall and a hardware-based firewall. This will ensure 100% protection from any external agent, be it from internet or from any hardware.
