Only terms that are defined in final publications&mdash;not drafts&mdash;are included here.</p> <ul> <li><strong>Multiple definitions.</strong> Some terms have multiple definitions. Terminology changes over time, and may differ based on the topic being addressed. <strong>Always refer to the source publication for the authoritative term and definition, and to see that information in its proper context.</strong></li> <li><strong>Inclusive language. </strong>We recognize that some NIST publications contain potentially biased terminology. As we revise publications, we are reviewing and editing that language based on NIST&rsquo;s <a href="https://web.archive.org/web/20230923105930/http://www.nist.gov/nist-research-library/nist-technical-series-publications-author-instructions#inclusive">inclusive language guidance</a>. New publications in development will also follow that guidance.</li> </ul> <p>The Glossary may be expanded to include&nbsp;relevant terms in external or supplemental sources, such as applicable laws and regulations. Recommendations for publications to be considered by NIST can be sent to <a href="https://web.archive.org/web/20230923105930/mailto:secglossary@nist.gov">secglossary@nist.gov</a>.
