 Firewalls
firewall software
Definition:
In computing, a firewall is a piece of hardware and/or software which functions
in a networked environment to prevent some communications forbidden by the security
policy, analogous to the function of firewalls in building construction. A firewall
has the basic task of controlling traffic between different zones of trust. Typical
zones of trust include the Internet (a zone with no trust) and an internal network
(a zone with high trust). The ultimate goal is to provide controlled connectivity
between zones of differing trust levels through the enforcement of a security policy
and connectivity model based on the least privilege principle. Proper configuration
of firewalls demands skill from the administrator. It requires considerable understanding
of network protocols and of computer security. Small mistakes can render a firewall
worthless as a security tool.
