ABSTRACT
Recalling the early days of the Internet, one can recount several reasons why the Internet came about:
• A vast communications medium to share electronic information • A multiple-path network that could survive localized outages • A means for computers from different manufacturers and different net-
works to talk to one another
Commerce and security at that time were not high on the agenda (with the exception of preserving network availability). The thought of commercializing the Internet in the early days was almost unheard of. In fact, it was considered improper etiquette to use the Internet to sell products and services. Commercial activity and its security needs are more-recent developments on the Internet, having come about strongly in the past few years.
