Requirements NIST SOURCE

Implement the following measures to disassociate user attributes or identifier assertion relationships among individuals, credential service providers, and relying parties: [measures].

Discussion (NIST Supplemental Guidance)

Federated identity solutions can create increased privacy risks due to the tracking and profiling of individuals. Using identifier mapping tables or cryptographic techniques to blind credential service providers and relying parties from each other or to make identity attributes less visible to transmitting parties can reduce these privacy risks.

No engineering interpretation has been authored for IA-8(6) 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. disassociability measures are defined;
  2. <IA-08(06)_ODP measures> to disassociate user attributes or identifier assertion relationships among individuals, credential service providers, and relying parties are implemented.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IA-8(6). 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.
