Requirements NIST SOURCE

Accept and electronically verify Personal Identity Verification-compliant credentials.

Discussion (NIST Supplemental Guidance)

Acceptance of Personal Identity Verification (PIV)-compliant credentials applies to organizations implementing logical access control and physical access control systems. PIV-compliant credentials are those credentials issued by federal agencies that conform to FIPS Publication 201 and supporting guidance documents. The adequacy and reliability of PIV card issuers are authorized using SP 800-79-2 . Acceptance of PIV-compliant credentials includes derived PIV credentials, the use of which is addressed in SP 800-166 . The DOD Common Access Card (CAC) is an example of a PIV credential.

No engineering interpretation has been authored for IA-2(12) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. Personal Identity Verification-compliant credentials are accepted and electronically verified.

Examine

[SELECT FROM: Identification and authentication policy; system security plan; procedures addressing user identification and authentication; system design documentation; system configuration settings and associated documentation; system audit records; PIV verification records; evidence of PIV credentials; PIV credential authorizations; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with system operations responsibilities; organizational personnel with account management responsibilities; organizational personnel with information security responsibilities; system/network administrators; system developers].

Test

[SELECT FROM: Mechanisms supporting and/or implementing acceptance and verification of PIV credentials].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IA-2(12). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
