For systems that process personally identifiable information:

Discussion (NIST Supplemental Guidance)

Managing the processing of personally identifiable information is an important aspect of protecting an individual’s privacy. Applying, monitoring for, and documenting exceptions to processing rules ensure that personally identifiable information is processed only in accordance with established privacy requirements.

Implementation Guidance

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for SC-7(24) 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. processing rules for systems that process personally identifiable information are defined;
  2. <SC-07(24)_ODP processing rules> are applied to data elements of personally identifiable information on systems that process personally identifiable information;
  3. permitted processing is monitored at the external interfaces to the systems that process personally identifiable information;
  4. permitted processing is monitored at key internal boundaries within the systems that process personally identifiable information;
  5. each processing exception is documented for systems that process personally identifiable information;
  6. exceptions for systems that process personally identifiable information are reviewed;
  7. exceptions for systems that process personally identifiable information that are no longer supported are removed.

Examine

[SELECT FROM: System and communications protection policy; procedures addressing boundary protection; personally identifiable information processing policies; list of key internal boundaries of the system; system design documentation; system configuration settings and associated documentation; enterprise security and privacy architecture documentation; system audit records; system security plan; privacy plan; personally identifiable information inventory documentation; data mapping documentation; other relevant documents or records].

Interview

[SELECT FROM: System/network administrators; organizational personnel with information security and privacy responsibilities; system developer; organizational personnel with boundary protection responsibilities].

Test

[SELECT FROM: Mechanisms implementing boundary protection capabilities].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-7(24). 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.
