Firewall is a device or a component that restricts access between a protected or an internal network from an external or untrustworthy network .A firewall basically limits unauthorized network access. It acts as a guard between an internal private network or intranet and an external public network or the Internet. As it is present at a junction of two networks it allows only a selective type of traffic to pass through. In this way a firewall provides a way to implement security policies for more secure networks .
