NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Audit Review – The assessment of an information system to evaluate the adequacy of implemented security controls, assure that they are functioning properly, identify vulnerabilities, and assist in implementation of new security controls where required. This assessment is conducted annually or whenever significant change has occurred and may lead to recertification of the information system. SOURCE: CNSSI-4009 Audit Trail – A record showing who has accessed an Information Technology (IT) system and what operations the user has performed during a given period. SOURCE: SP 800-47 A chronological record that reconstructs and examines the sequence of activities surrounding or leading to a specific operation, procedure, or event in a security relevant transaction from inception to final result. SOURCE: CNSSI-4009 Authenticate – To confirm the identity of an entity when that identity is presented. SOURCE: SP 800-32 To verify the identity of a user, user device, or other entity. SOURCE: CNSSI-4009 Authentication – Verifying the identity of a user, process, or device, often as a prerequisite to allowing access to resources in an information system. SOURCE: SP 800-53; SP 800-53A; SP 800-27; FIPS 200 Authentication – The process of establishing confidence of authenticity. SOURCE: FIPS 201 Authentication – Encompasses identity verification, message origin authentication, and message content authentication. SOURCE: FIPS 190 Authentication – A process that establishes the origin of information or determines an entity’s identity. SOURCE: SP 800-21 The process of verifying the identity or other attributes claimed by or assumed of an entity (user, process, or device), or to verify the source and integrity of data. SOURCE: CNSSI-4009 Pg 14
NIST IR 7298 Revision 1, Glossary of Key Information Security Terms Authentication Code – A cryptographic checksum based on an Approved security function (also known as a Message Authentication Code [MAC]). SOURCE: FIPS 140-2 Authentication, Electronic – The process of establishing confidence in user identities electronically presented to an information system. SOURCE: SP 800-63 Authentication Mechanism – Hardware-or software-based mechanisms that force users to prove their identity before accessing data on a device. SOURCE: SP 800-72; SP 800-124 Hardware or software-based mechanisms that forces users, devices, or processes to prove their identity before accessing data on an information system. SOURCE: CNSSI-4009 Authentication Mode – A block cipher mode of operation that can provide assurance of the authenticity and, therefore, the integrity of data. SOURCE: SP 800-38B Authentication Period – The maximum acceptable period between any initial authentication process and subsequent reauthentication processes during a single terminal session or during the period data is being accessed. SOURCE: CNSSI-4009 Authentication Protocol – A well-specified message exchange process that verifies possession of a token to remotely authenticate a claimant. Some authentication protocols also generate cryptographic keys that are used to protect an entire session, so that the data transferred in the session is cryptographically protected. SOURCE: SP 800-63 A well-specified message exchange process between a claimant and a verifier that enables the verifier to confirm the claimant’s identity. SOURCE: CNSSI-4009 Authentication Tag – A pair of bit strings associated to data to provide assurance of its authenticity. SOURCE: SP 800-38B Authentication Token – Authentication information conveyed during an authentication exchange. SOURCE: FIPS 196 Pg 15
