Abstract

[Superseded by NISTIR 7298 Revision 1: http://www.nist.gov/manuscript-publication-search.cfm?pub_id=907638] This glossary of basic security terms has been extracted from NIST Federal Information Processing Standards (FIPS) and the Special Publication (SP) 800 series. The terms included are not all inclusive of terms found in these publications, but are a subset of basic terms that are most frequently used. The purpose of this glossary is to provide a central resource of definitions most commonly used in NIST security publications. Each entry in the glossary points to one or more source NIST publications, and in addition, supplemental sources where appropriate. As we are continuously refreshing our publication suite, terms included in the glossary come from our more recent publications and existing FIPS.
