Mitigating Controls (NIST 800-53 r5) AI

Explicitly enforces information-flow rules that block private resources from reaching unauthorized external spheres.

Enforces approved authorizations so private resources cannot be transmitted outside their intended sphere.

Boundary controls monitor and restrict communications that would otherwise leak private resources.

Requires confidentiality protection on transmitted data, directly stopping exposure of private resources.

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.

prevents

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

prevents

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

prevents

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

finds

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

mitigates

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

mitigates

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