Mitigating Controls (NIST 800-53 r5) AI

Directly enforces policy-based information flow rules that block transmission of sensitive data to unauthorized actors.

Enforces authorizations on logical access so that sensitive data is not released to unauthorized recipients.

Requires validation of outbound information to ensure sensitive content is not disclosed in responses or messages.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent insertion of sensitive data into application outputs and messages.

DE.CM-09 partial match

Monitoring runtime data flows and outputs can detect sensitive data being transmitted.

PR.DS-02 partial match
prevents

Protecting data-in-transit can include filtering or encrypting to avoid exposing sensitive content.

PR.DS-10 partial match

prevents

Data-masking techniques can prevent sensitive values from appearing in transmitted payloads.

mitigates

Classification identifies sensitive data so it is not inadvertently transmitted.

mitigates

Labelling makes sensitive data visible to developers and prevents accidental inclusion in outbound messages.

mitigates

Information-transfer rules directly govern what data may be sent to external parties.

mitigates

PII-protection requirements reduce the chance of sending personal data to unauthorized recipients.

mitigates

DLP controls inspect and block outbound flows that contain sensitive information.
