PT — Personally Identifiable Information Processing and Transparency · NIST SP 800-53 Release 5.2.0

Privacy
Official NIST control content

Control statement

Apply [Organization-defined: processing conditions] for specific categories of personally identifiable information.

Official NIST discussion

Discussion

Organizations apply any conditions or protections that may be necessary for specific categories of personally identifiable information. These conditions may be required by laws, executive orders, directives, regulations, policies, standards, or guidelines. The requirements may also come from the results of privacy risk assessments that factor in contextual changes that may result in an organizational determination that a particular category of personally identifiable information is particularly sensitive or raises particular privacy risks. Organizations consult with the senior agency official for privacy and legal counsel regarding any protections that may be necessary.

Official OSCAL parameters

Organization-defined parameters

These values must be resolved through the organization’s tailoring and governance process. Bracketed parameter references in the control text identify where a decision is required.

From control text to operational evidence

Use Specific Categories of Personally Identifiable Information as a testable risk decision. Translate the official statement into accountable people, repeatable processes, configured technology, and evidence that demonstrates the outcome over time. In this family, pay particular attention to privacy authority, purpose, transparency, consent, individual rights, and data-processing governance.

Implementation workflow

  • Define the control boundary, responsible owner, inherited portions, and systems or processes in scope.
  • Resolve each organization-defined parameter before declaring the control implemented.
  • Document how the implementation satisfies every clause of the official control statement.
  • Collect evidence as a normal byproduct of operation rather than only before an assessment.
  • Review exceptions, changes, and monitoring results on a risk-based cadence.

Evidence examples

  • privacy notices and consent records
  • authority and purpose documentation
  • data-processing inventories
  • individual request and redress records

Common failure patterns

  • collection justified by convenience rather than authority
  • notices do not reflect actual processing
  • secondary use expands without review
  • retention and deletion commitments not enforced

Questions practitioners should ask

  • What risk decision is this control intended to support in this system?
  • Which parts are implemented locally, inherited, shared, or not applicable—and what evidence supports that decision?
  • Do the documented narrative, deployed configuration, operating process, and collected evidence agree?
  • What event or threshold requires the implementation to be reviewed or changed?

PT-7(1) — Social Security Numbers

Privacy

When a system processes Social Security numbers:

  1. (a)Eliminate unnecessary collection, maintenance, and use of Social Security numbers, and explore alternatives to their use as a personal identifier;
  2. (b)Do not deny any individual any right, benefit, or privilege provided by law because of such individual’s refusal to disclose his or her Social Security number; and
  3. (c)Inform any individual who is asked to disclose his or her Social Security number whether that disclosure is mandatory or voluntary, by what statutory or other authority such number is solicited, and what uses will be made of it.
Official discussion

Federal law and policy establish specific requirements for organizations’ processing of Social Security numbers. Organizations take steps to eliminate unnecessary uses of Social Security numbers and other sensitive information and observe any particular requirements that apply.

Assessment objectives and methods
  1. PT-07(01)(a)
    1. PT-07(01)(a)[01]when a system processes Social Security numbers, the unnecessary collection, maintenance, and use of Social Security numbers are eliminated;

  2. PT-07(01)(b)when a system processes Social Security numbers, individual rights, benefits, or privileges provided by law are not denied because of an individual’s refusal to disclose their Social Security number;
  3. PT-07(01)(c)
    1. PT-07(01)(c)[01]when a system processes Social Security numbers, any individual who is asked to disclose their Social Security number is informed whether that disclosure is mandatory or voluntary, by what statutory or other authority such number is solicited, and what uses will be made of it;
    2. PT-07(01)(c)[02]when a system processes Social Security numbers, any individual who is asked to disclose their Social Security number is informed by what statutory or other authority the number is solicited;
    3. PT-07(01)(c)[03]when a system processes Social Security numbers, any individual who is asked to disclose their Social Security number is informed what uses will be made of it.
