FAQ: Firewall Admins Guide to Porn version 1.0.1 (Jan 15, 2000). One of the more frequent problem security administrators will face is porn. It is a popular Internet application, and even when restrictions are put into place, users find ways of getting around them. At the same time, users tend to be clueless as to the knowledge firewall admins have of their surfing habits. Every administrator of a large company that I know of has had to confront this issue, but not much is discussed about the topic in the literature. This document is intended as a guide for firewall admins in this area.
