Mitigating Controls (NIST 800-53 r5) AI

MP-6 Media Sanitization good match

Requires sanitization of media before disposal, release, or reuse, directly stopping sensitive information from remaining in resources made available to unauthorized parties.

SI-19 De-identification good match

Mandates removal of specified PII elements from datasets before further use or sharing, addressing a subset of the improper-removal cases.

PR.DS-10 mostly match
prevents

Directly addresses removal of confidential data from process memory and similar in-use contexts before exposure.

A.8.10 Information deletion full match
degrades

Explicit information-deletion control directly addresses improper removal of sensitive data.

A.8.11 Data masking full match
prevents

Data-masking techniques can substitute for removal when full deletion is impractical.

A.8.33 Test information mostly match
prevents

Test-data protection rules require sanitization of production data used in testing.

A.5.12 Classification of information partial match
prevents

Classification identifies sensitive data that must be removed before storage or transfer.

A.5.14 Information transfer partial match
prevents

Information-transfer rules can require sanitization of sensitive content before sharing.

A.5.34 Privacy and protection of PII partial match
prevents

PII-protection requirements include removing identifiers before storage or disclosure.
