Firewalls - guardians for areas of the network. The firewall must permit only authorized traffic. The firewall itself must be immune to penetration. Setting up an Internet Firewall without a comprehensive security policy is like placing a steel door on a tent.
Architecture of firewalls is based on : packet filtering, proxies, state inspection, or network address hiding and translation
