What Is a Firewall?

The most effective way to secure an Internet link is to put a firewall between the local

network and the Internet. A

firewall

is a system designed to prevent unauthorized access to

or from a secured network. Firewalls act as locked doors between internal and external

networks: data that meets certain requirements is allowed through, while unauthorized data

is not.

To provide robust security, a firewall must track and control the flow of communication

passing through it. To reach control decisions for TCP/IP-based services, (such as whether

to accept, reject, authenticate, encrypt, and/or log communication attempts), a firewall

must obtain, store, retrieve, and manipulate information derived from all communication

layers and other applications.
