What is a Firewall?

The Internet is a network of computer networks. It has evolved from the interconnection of networks around the globe. Interconnection is a good thing; it allows the free exchange of information via the Web, e-mail and file transfer. It also carries a price namely the risk that your Internet connection may be used by "hackers" (or as some would rather call them "crackers") to gain unauthorized access to your local network. Availability of computing facilities can also be targeted by Denial of Service (DoS) attacks.

A firewall is a system that implements and enforces an access control (or security) policy between two networks; it usually guards an internal private network from an external public one, isolating an intranet from the Internet. Essentially a firewall connects two or more networks but only allows specified forms of traffic to flow between them. The firewall is a means by which a security policy can be enforced.
