1. Introduction

   This Glossary provides an internally consistent, complementary set of
   abbreviations, definitions, explanations, and recommendations for use
   of terminology related to information system security. The intent of
   this Glossary is to improve the comprehensibility of Internet
   Standards documents (ISDs)--i.e., RFCs, Internet-Drafts, and other
   material produced as part of the Internet Standards Process [R2026]--
   and of all other Internet material, too. Some non-security terms are
   included to make the Glossary self-contained, but more complete lists
   of networking terms are available elsewhere [R1208, R1983].

   Some glossaries (e.g., [Raym]) list terms that are not listed here
   but could be applied to Internet security. However, those terms have
   not been included in this Glossary because they are not appropriate
   for ISDs.

   This Glossary marks terms and definitions as being either endorsed or
   deprecated for use in ISDs, but this Glossary is not an Internet
   standard. The key words "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY",
   and "OPTIONAL" are intended to be interpreted the same way as in an
   Internet Standard [R2119], but this guidance represents only the
   recommendations of this author. However, this Glossary includes
   reasons for the recommendations--particularly for the SHOULD NOTs--so
   that readers can judge for themselves whether to follow the
   recommendations.
