“The Firewalls FAQ is currently undergoing revision. The maintainers welcome input and comments on the contents of this FAQ.”

“A firewall is a system or group of systems that enforces an access control policy between two networks. The actual means by which this is accomplished varies widely, but in principle, the firewall can be thought of as a pair of mechanisms: one which exists to block traffic, and the other which exists to permit traffic.”

Ingham, K., Forrest S., A History and Survey of Network Firewalls, University of New Mexico,, 2001.

“The protocols used on the Internet for these layers, as well as all other Internet
standards are speci_ed by documents known as Requests for Comments (RFCs).”

“Examples of successful or attempted intrusions around the same time include:
Cliord Stoll's discovery of German spies tampering with his system [Stoll 1988;
1989], and Bill Cheswick's \Evening with Berferd" [1992] in which he set up a simple
Electronic \jail" for an attacker. In this jail, the attacker was unable to a_ect
the real system but was left with the impression that he or she had successfully
broken in.”

“The crackers used bogus Unix shell accounts in Chicago, New York, Germany, and Hong Kong to cover their tracks.”
