Internet Security: New Problems, New Solutions

Lance J. Hoffman

Mar 03, 1997

Abstract

Risk analysis, simple authentication, and encryption are security mechanisms which, while not perfect, used to work reasonably well to provide Internet security. But the Internet world has recently become populated by millions of new users who do not always share the same values or objectives as almost all of its previous inhabitants. Firewalls, exportable encryption, and user tokens are just some of the newer mechanisms that are increasingly used as well.

This presentation first examines the old and new tools for Internet security and privacy, and then turns its attention to the public policy problems exacerbated by the Internet. These include what law governs in cyberspace; invasion of privacy by unsolicited e-mail (spam), newsgroup lookups, and other means; freedom of speech, censorship, and user choice; international encryption and accountability; Web page content control; advertising on the Net; electronic cash and anonymity; and whether intellectual property laws are hopelessly out of date.
