A Firewall is hardware or software device used to separate internal networks and workstations from insecure environments. A firewall prevents computers on a network from communicating directly with external computer systems. It typically acts as a barrier through which all information passing between the networks and the external systems must travel. The firewall software analyzes information passing between the two and rejects it if it does not conform to pre-configured rules.
