All those who have Windows XP/Vista/7 installed in their machine, would have seen the adjoining icon. This is the icon of FIREWALL. We all listen this term quite often, but actually what is Firewall? Is it hardware or software? Do we need it in personal computer/laptop or is it only needed in organizations? Is it different from anti-virus? So let us have a closer and deeper look at this very essential needed thing. BUSTING THE MYTHS First of all we need to have an open mind and clear certain myths we have regarding Firewall. Myth 1: Firewall is software Answer: No, it can be software as well as hardware. In large business organizations the functionality is met by hardware and software Firewall. But in small scale organizations or Personal computers/laptops software solves the functionality. Myth 2: Personal Computers/Laptops don’t need Firewall Answer: If you are connected to a network, it might be local or internet; then you definitely need a firewall. What is need of the firewall will be discussed later. Myth 3: Antivirus and firewall are same Answer: The answer is BIG NO. They both are entirely different thing. Firewall is for protection from threats from network, whereas anti-virus works against virus on the local machine where it is installed by scanning everything which is installed or running. But these days firewall is integrated inside Antivirus (these days antivirus provides real time scanning which solve purpose of firewall as well), so the need of having a firewall separately on personal computer/laptop is optional. But in organizations they are quite essential. We will explore it further later
