1 Introduction

   The purpose of this document is to express what the engineering
   community as represented by the IETF expects of Internet Service
   Providers (ISPs) with respect to security.  This document is
   addressed to ISPs.

   By informing ISPs of what this community hopes and expects of them,
   the community hopes to encourage ISPs to become proactive in making
   security not only a priority, but something to which they point with
   pride when selling their services.

   Under no circumstances is it the intention of this document to
   dictate business practices.
