Mitigating Controls (NIST 800-53 r5) AI

AC-16 Security and Privacy Attributes good match

Associates security and privacy attributes with data and subjects so that incompatible stakeholder policies can be reconciled before exposure occurs.

AC-21 Information Sharing good match

Requires explicit checking that a sharing partner's authorizations match the sensitivity of the information, preventing release under mismatched policies.

AC-4 Information Flow Enforcement partial match

Enforces approved information flow policies between systems, directly stopping exposure when developer and stakeholder policies conflict.

PT-3 Personally Identifiable Information Processing Purposes partial match

Documents the specific purposes for processing PII, surfacing and aligning conflicting stakeholder policies before data exposure.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

GV.OC-02 mostly match
prevents

Understanding stakeholder needs directly surfaces incompatible sensitivity expectations that produce the exposure.

GV.PO-01 mostly match
prevents

Establishing risk-management policy based on organizational context is the primary mechanism for aligning divergent sensitivity rules.

GV.OC-03 partial match
prevents

Regulatory and privacy obligations often define the conflicting sensitivity views that the weakness fails to reconcile.

GV.PO-02 partial match
prevents

Periodic policy review can detect and correct stakeholder-policy mismatches before they cause exposure.

PR.AA-05 partial match
prevents

Defining and enforcing access policy is one concrete place where incompatible sensitivity decisions manifest as unauthorized disclosure.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.5.12 Classification of information mostly match
prevents

Classification directly addresses mismatched sensitivity views by defining what must be protected.

A.5.31 Legal, statutory, regulatory and contractual requirements mostly match
prevents

Legal and contractual requirements often impose stricter sensitivity rules than developer policy.

A.5.34 Privacy and protection of PII mostly match
prevents

PII protection explicitly reconciles developer exposure with data-subject or regulator expectations.

A.5.1 Policies for information security partial match
prevents

High-level policy can mandate consistent handling of sensitive data across stakeholder expectations.

A.5.13 Labelling of information partial match
prevents

Labelling helps communicate classification decisions and reduce policy conflicts.

A.5.14 Information transfer partial match
mitigates

Transfer rules can enforce consistent protection when data crosses stakeholder boundaries.
