The term "fire wall" originally meant, and still means, a fireproof wall intended to prevent the spread of fire from one room or area of a building to another. The internet is a volatile and unsafe environment when viewed from a computer-security perspective, therefore "firewall" is an excellent metaphor for network security.

In computer networking, the term firewall is not merely descriptive of a general idea. It has come to mean some very precise things.
