So what is a firewall?

A firewall is a device that controls network traffic (all incoming and outgoing data), and can either deny or allow information to enter or leave your personal computer or network.  There are two types of firewall: software and hardware ones

The software is a program that monitors the network traffic. Newer versions of Windows,already come with the software installed as default. This is mostly used by single computers says engineers at kyrus technologies

The hardware firewall is a device that you can install at the point where your network (LAN) connects to the Internet.

Consultant Shravan KP says that the best policy is to have both software and hardware firewalls working together if you want to have more security, even if you have a small business or just home computer needs. “You must be wondering why to use any firewall besides a good anti-virus software program. Well, remember that it always takes some time for the antivirus companies to develop a protection against the new viruses, and a firewall may prevent you from disseminating a new virus in case one infiltrates your computer. Besides, it may also protect you against ill-intentioned people. The ideal is to have a good antivirus always updated and a good firewall installed and configured.”

As a specialist in security systems, Shravan KP reinforces the importance of using firewall, even in your home computer, since there are numerous ways of stealing bank passwords, credit card and personal information from your computers. “The Internet is not dangerous if used with security. Nowadays the use of firewall in both homes and companies, be them large or small, is highly necessary, so you can safely enjoy all the benefits of the Internet.”
