Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces access restrictions on project issues and linked merge requests so that confidential branch names are not exposed to unauthorized users.

prevent

Enforces information-flow rules between merge-request metadata and issue views to block leakage of sensitive branch names.

prevent

Limits user privileges to the minimum required, reducing the chance that an account can reach issue records containing confidential branch references.

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
prevents

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

Protecting data-in-use includes removing confidential values before they are processed or sent.

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.
