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.

PR.AA-05 mostly match
prevents

Enforcing least-privilege access permissions directly prevents private resources from being exposed outside their intended sphere.

PR.IR-01 mostly match
prevents

Logical segmentation and unauthorized-access protections stop resources from leaking into untrusted domains.

PR.DS-01 partial match
prevents

Encryption of data-at-rest reduces the value of any leaked resource but does not address the transmission flaw itself.

PR.DS-02 partial match
prevents

Protecting data-in-transit mitigates exposure during movement yet does not prevent the underlying boundary violation.

A.8.3 Information access restriction full match
prevents

Information-access-restriction directly prevents private resources from being exposed beyond intended boundaries.

A.5.15 Access control mostly match
prevents

Access-control mechanisms limit who can receive resources that should remain internal.

A.5.18 Access rights mostly match
prevents

Managing access rights helps ensure resources are not granted to untrusted parties.

A.8.12 Data leakage prevention mostly match
finds

Data-leakage-prevention technologies specifically block unintended transmission of sensitive resources.

A.5.14 Information transfer partial match
mitigates

Information-transfer rules can prevent unintended disclosure of private resources outside the product.

A.8.20 Networks security partial match
mitigates

Network-security controls can limit exposure paths but do not address the root resource-leak logic.
