Hello friends. Nowadays hacking is on a boom. Many popular websites and companies got hacked recently by some hackers. Though we are not big as a company, but still we also need to pay attention towards some security. So for getting rid of viruses we have antivirus installed. But do you know about firewall. And if yes, then which is the best firewall. So lets discuss this in some steps.
What is a Firewall?
A firewall can either be software-based or hardware-based and is used to help keep a network secure. Its primary objective is to control the incoming and outgoing network traffic by analyzing the data packets and determining whether it should be allowed through or not, based on a predetermined rule set.
So in general it means that, its a wall between our computer and the Internet (outside world) and it filters the connections established.
Most of us are using windows as our operating system. So it has its own firewall. But i would like to inform you that its of NO USE. So the question still remains, which is the best firewall to use in our machine.
Which is the best firewall ???
Comodo Firewall is one of the best firewall which can be used to protect your computer. It is available for free. It protects your pc,laptop from intruders from outside world. Hackers try to enter your pc using gates which are called PORTS. They may use trojan or rats to enter your pc. There are many open ports in your pc which are not secure. Now Comodo firewall just closes this ports automatically, thus securing your pc from hackers.
How to use it??
Just install it in your pc,laptop and leave your security in the hands of comodo firewall. Now whenever a software tries to establish connection over internet, the firewall prompts you for permission whether to allow it or not. Now if you trust the software you have installed, then allow it. Like for example, when you open a browser, comodo will ask for permission once, then you can allow it.
If a trojan or other malicious program try to establish connection it will block it.
