Glossary terms and definitions last updated: March 10, 2022
This Glossary consists of terms and definitions extracted verbatim from NIST's cybersecurity- and privacy-related Federal Information Processing Standards (FIPS), NIST Special Publications (SPs), and NIST Internal/Interagency Reports (IRs), as well as from Committee on National Security Systems (CNSS) Instruction CNSSI-4009. Only terms that are defined in final publications—not drafts—are included here.
Always refer to the source publication for the authoritative term and definition, and to see that information in its proper context.
The Glossary may be expanded to include terms from withdrawn publications and relevant terms in external or supplemental sources, such as applicable laws and regulations.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 secglossary@nist.gov. HOWEVER, terms without a source publication will not be independently added by NIST to the Glossary.
See NISTIR 7298 Rev. 3 for additional details about this Glossary.
* "Relevance" merely indicates the search engine's score for a document. It is based on the search parameters and information in the document's detailed record.
